The meeting will be held on Thursday, June 7, 2018, at 10:30 a.m. local time at the Hotel Palomar located at 10740 Wilshire Boulevard, Los Angeles, California 90024, for the following purposes:

This proxy statement and proxy card are furnished in connection with the solicitation of proxies to be voted at the 2018 Annual Meeting of Stockholders (the "Annual Meeting" or the "2018 Annual Meeting") of Boingo Wireless, Inc.

You have received these proxy materials because the Board of Directors (our "Board" or the "Board of Directors") of Boingo Wireless, Inc. ("we", "us" or the "Company") is soliciting your proxy to vote at the 2018 Annual Meeting.

Why did I receive a Notice of Internet Availability of Proxy Materials in the mail instead of a printed set of proxy materials?

Pursuant to rules adopted by the Securities and Exchange Commission, we are permitted to furnish our proxy materials over the Internet to our stockholders by delivering a Notice in the mail. As a result, only stockholders that specifically request a printed copy of the proxy statement will receive one. Instead, the Notice instructs stockholders on how to access and review the proxy statement and annual report over the Internet at www.proxyvote.com. The Notice also instructs stockholders on how they may submit their proxy over the Internet. If a stockholder who received a Notice would like to receive a printed copy of our proxy materials, such stockholder should follow the instructions for requesting these materials contained in the Notice.

Only stockholders of record at the close of business on April 13, 2018 will be entitled to vote at the Annual Meeting. On this record date, there were 41,756,449 shares of Company common stock ("Common Stock") outstanding. The holders of Common Stock have the right to one vote for each share they held as of the record date.

In accordance with Delaware law, a list of stockholders entitled to vote at the meeting will be available at the place of the Annual Meeting on June 7, 2018 and will be accessible for ten days prior to the meeting at our principal place of business, 10960 Wilshire Blvd, 23rd Floor, Los Angeles, CA 90024, between the hours of 9:00 a.m. and 5:00 p.m. (Pacific Time).

If on April 13, 2018, your shares were registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, then you are a stockholder of record. Stockholders of record may vote by using the Internet, by telephone or (if you received a proxy card by mail) by mail as described below. Stockholders also may attend the meeting and vote in person. If you hold shares

through a bank or broker, please refer to your proxy card, Notice or other information forwarded by your bank or broker to see which voting options are available to you.

Written ballots will be passed out to anyone who wants to vote at the Annual Meeting. If you hold your shares in "street name," you must obtain a proxy, executed in your favor, from the holder of record to be able to vote in person at the Annual Meeting.

If you return a signed and dated proxy card without marking any voting selections, your shares will be voted (i) "For" the election of all two of your Board's nominees for director, (ii) "For" ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018, (iii) "For" the advisory approval of our Company's executive compensation for the year ended December 31, 2017 as disclosed herein, and (iv) "For" a frequency of the advisory vote on the Company's executive compensation of one year. However, if you are not a record holder, such as where your shares are held through a broker, nominee, fiduciary or other custodian, you must provide voting instructions to the record holder of the shares in accordance with the record holder's requirements in order for your shares to be properly voted. If any other matter is properly presented at the meeting, your proxy (one of the individuals named on your proxy card) will vote your shares using his best judgment.

We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

In addition, we have hired Alliance Advisors, at an estimated cost of $15,000, plus reimbursement of reasonable expenses, to assist in the solicitation of proxies.

If you receive more than one proxy card or Notice, your shares are registered in more than one name or are registered in different accounts. Please complete, sign and return each proxy card or submit a proxy for each Notice to ensure that all of your shares are voted.

If you reside at the same address as another Boingo stockholder, you and other Boingo stockholders residing at the same address will receive a single copy of the Notice of Availabilty of Proxy Materials. If you wish to receive a separate copy of the Notice of Availabilty of Proxy Materials, you may do so by making a written or oral request to: Boingo Wireless, Inc., 10960 Wilshire Blvd., 23rd Floor, Los Angeles, California 90024, Attention: Corporate Secretary. Upon your request, we will promptly deliver a separate copy to you. The Annual Report, Proxy Statement and Notice are also available at www.proxyvote.com.

Yes. You can revoke your proxy at any time before the final vote at the meeting. You may revoke your proxy in any one of three ways:

Proxies may be solicited on behalf of our Board, without additional compensation, by the Company's directors and employees.

In addition, we have hired Alliance Advisors, at an estimated cost of $15,000, plus reimbursement of reasonable expenses, to assist in the solicitation of proxies.

The original solicitation of proxies by mail may be supplemented by telephone, telegram, facsimile, electronic mail, and personal solicitation by our directors and officers (who will receive no additional compensation for such solicitation activities). You may also be solicited by advertisements in periodicals, press releases issued by us and postings on our corporate website at www.boingo.com. Unless expressly indicated otherwise, information contained on our corporate website is not part of this proxy statement.

Votes will be counted by the inspector of election appointed for the meeting, who will separately count "For" and "Against" votes, abstentions and broker non-votes. Abstentions will be counted as present for purposes of determining the presence of a quorum. For Proposal 1, abstentions will not be considered as votes cast for or against any director, and will therefore have no effect on the outcome of the vote. For Proposals 2, 3 and 4, abstentions will not be considered as votes cast for or against any proposal, and will therefore have no effect on the outcome of the vote. Broker non-votes, as described in the next paragraph, have no effect and will not be counted towards the vote total for such proposals.

If your shares are held by your bank or broker as your nominee (that is, in "street name"), you will need to obtain a voting instruction form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker to vote your shares. If you do not give instructions to your broker, your broker can vote your shares with respect to "discretionary" items, but not with respect to "non-discretionary" items. Discretionary items are proposals considered routine under the rules of the New York Stock Exchange ("NYSE") on which your broker may vote shares held in street name without your voting instructions. On non-discretionary items for which you do not give your broker instructions, the shares will be treated as broker non-votes. Under current

NYSE rules, any election of a member of the Board of Directors, whether contested or uncontested, is considered "non-discretionary" and therefore brokers are not permitted to vote your shares held in street name for the election of directors in the absence of instructions from you. All of our proposals, except for Proposal 2, are "non-discretionary" and therefore if you hold your shares through a broker, nominee, fiduciary or other custodian, your shares will not be voted on those proposals unless you provide voting instructions to the record holder.

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if a majority of all shares outstanding on April 13, 2018, the record date, are represented at the meeting by stockholders present in person or by proxy. On the record date, there were 41,756,449 shares of Common Stock outstanding and entitled to vote. Thus 20,878,225 shares must be represented by stockholders present at the meeting or by proxy to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy vote or vote at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement.

We will count a properly executed proxy card marked "Abstain" as present for purposes of determining whether a quorum is present, but the shares represented by that proxy card will not be voted at the Annual Meeting for the proposals so marked.

Preliminary voting results will be announced at the Annual Meeting. Final voting results will be available on a Current Report on Form 8-K filed with the Securities and Exchange Commission within four business days after the end of the Annual Meeting.

If you wish to submit a proposal to be considered for inclusion in next year's proxy materials, your proposal must be in proper form according to SEC Regulation 14A, Rule 14a-8 and received by the Secretary of the Company on or before December 25, 2018. If you wish to submit a proposal to be presented at the 2019 Annual Meeting of Stockholders, but which will not be included in the Company's proxy materials, including to nominate a director, your Solicitation Notice, as defined in our bylaws, must be received by the Secretary of the Company at Boingo Wireless, Inc., 10960 Wilshire Blvd, 23rd Floor, Los Angeles, CA 90024, Attn: Secretary, no earlier than February 8, 2019 and no later than March 10, 2019. You are advised to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations. Boingo Wireless' current bylaws may be found on the corporate governance subsection of the investor relations section of our corporate website at www.boingo.com.

As required under the listing standards of the Nasdaq Global Market ("Nasdaq"), a majority of the members of a Nasdaq-listed company's board of directors must qualify as "independent," as affirmatively determined by its board of directors. Our Board of Directors consults with counsel to ensure that the Board of Directors' determinations are consistent with all relevant laws and regulations regarding the definition of "independent," including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

Management and outside counsel have reviewed the directors' responses to a questionnaire asking about their transactions, relationships and arrangements with the Company (and those of their immediate family members) and other potential conflicts of interest. Other than as set forth in this proxy statement, these questionnaires did not disclose any transactions, relationships, or arrangements that question the independence of our directors or director nominees. After reviewing this information, our Board of Directors affirmatively determined that, except for David Hagan (our Chief Executive Officer), all of our directors are independent directors within the meaning of the applicable Nasdaq listing standards.

As required under Nasdaq listing standards, our independent directors meet in regularly scheduled executive sessions at which only independent directors are present. Lance Rosenzweig, our lead independent director, presides over these executive sessions. During 2017, the Board had an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee, a

Cybersecurity Committee and a Steering Committee. The following table provides membership information for each of such Board committees during 2017:

Below is a description of each of the committee of the Board of Directors. The Board of Directors has determined that each member of the Audit, Compensation and Nominating and Corporate Governance Committees meets the applicable rules and regulations regarding "independence" and also that each member of the Audit Committee, Compensation Committee, Nominating and Corporate Governance Committee, Steering Committee and Cybersecurity Committee is free of any relationship that would interfere with his or her individual exercise of independent judgment with regard to the Company.

Our Audit Committee charter can be found on the corporate governance section of our corporate website at www.boingo.com. Each of Maury Austin, Charles Boesenberg, Terrell Jones and Lance Rosenzweig served on the Audit Committee of the Board of Directors during 2017. Mr. Boesenberg retired from the Board and its committees on which he served in July 2017. The Audit Committee met four times during 2017.

The Board of Directors annually reviews the Nasdaq listing standards definition of independence for Audit Committee members and has determined that all members of our Audit Committee are independent as currently defined under Nasdaq listing standards. The Board of Directors has determined that Maury Austin, Terrell Jones and Lance Rosenzweig are each an audit committee financial expert as defined by Item 407(d) of Regulation S-K. The Board made a qualitative assessment of Mr. Austin's level of knowledge and experience based on a number of factors, including his experience as a chief financial officer of various publicly and privately traded companies, experience in accounting and finance roles for over 35 years and his degrees in business management. The Board also made a qualitative assessment of Mr. Jones' level of knowledge and experience based on a number of factors, including his prior experience as chief executive officer of two publicly traded companies, and prior service as a director on the audit committee of three other public companies. The Board also made a qualitative assessment of Mr. Rosenzweig's level of knowledge and experience based on a number of factors, including his experience as a partner of a leading private equity firm, prior experience as a chief executive officer of various publicly and privately traded companies and his prior experience in the banking industry.

A more detailed description of the Compensation Committee's functions can be found in our Compensation Committee Charter. The charter is published in the corporate governance section of our website at www.boingo.com. Each of Charles Boesenberg, David Cutrer, Chuck Davis and Mike Finley

served on the Compensation Committee of the Board of Directors during 2017. Mr. Boesenberg retired as a member of our Board and from the Board committees on which he served in July 2017 and Mr. Cutrer left the Board and the committees on which he served in September 2017. Mr. Boesenberg served as the Chair of the Compensation Committee until his retirement. In connection with Mr. Boesenberg's retirement and appointing a new Chair, the Committee considered various attributes of a new Chair and subsequently appointed Mike Finley as Chair of the Compensation Committee. All members of the Compensation Committee are independent as currently defined under Nasdaq listing standards.

The Compensation Committee met nine times during 2017. Mr. Hagan, our principal executive officer, does not participate in the determination of his own compensation or the compensation of directors. However, he makes recommendations to the Compensation Committee regarding the amount and form of the compensation of the other executive officers and key employees, and he often participates in the Committee's deliberations about their compensation. Mr. Hovenier, our Chief Financial Officer, and Bethany Ellis, our Senior Vice President Human Resources, also assist the Committee in its executive officer, director and employee compensation deliberations. No other executive officers participate in the determination of the amount or form of the compensation of executive officers or directors. The Compensation Committee has delegated authority to a grant committee, currently comprised of our Chief Executive Officer and our Chief Financial Officer, to approve awards within certain specified parameters to non-executive employees of the Company.

The Croner Company advised the Compensation Committee during 2017 on executive compensation-related matters. The Compensation Committee has assessed the independence of The Croner Company pursuant to SEC rules and Nasdaq listing standards and determined that no impermissible conflict of interest exists that would prevent The Croner Company from independently advising the Compensation Committee.

Our Nominating and Corporate Governance Committee is responsible for, among other things:

Our Nominating and Corporate Governance Committee charter can be found on the corporate governance section of our corporate website at www.boingo.com. Each of Chuck Davis, Terrell Jones and Kathy Misunas served on the Nominating and Corporate Governance Committee of the Board of Directors during 2017. All members of the Nominating and Corporate Governance Committee are independent as currently defined under Nasdaq listing standards. The Nominating and Corporate Governance Committee met six times during 2017.

Our Nominating and Corporate Governance Committee believes that the minimum qualifications and skills that candidates for director should possess include (a) the highest professional and personal

ethics and values, (b) broad experience at the policy-making level in business, government, education, technology or public interest, (c) a commitment to enhancing stockholder value and (d) sufficient time to carry out their duties and to provide insight and practical wisdom based on experience. The committee also considers the following factors, in no particular order of importance: (a) various and relevant career experience, (b) relevant skills, such as an understanding of the Company's business, (c) financial expertise, (d) diversity and (e) local and community ties. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time.

Candidates for director nominees are reviewed in the context of the current composition of our Board, our strategy and operating requirements and the long-term interests of our stockholders. While we do not have a formal policy on diversity, our Nominating and Corporate Governance Committee considers diversity of experience as one of the factors it considers in conducting its assessment of director nominees, along with such other factors as it deems appropriate given the then current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability. In the case of incumbent directors, our Nominating and Corporate Governance Committee reviews such directors' overall service to the Company during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors' independence. In the case of new director candidates, the committee also determines whether the nominee must be independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary.

The Nominating and Corporate Governance Committee uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Committee meets to discuss and consider such candidates' qualifications and then selects a nominee for recommendation to the Board by majority vote.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders and evaluate them using the same criteria as candidates identified by the Board or the Nominating and Corporate Governance Committee for consideration. If a stockholder of the Company wishes to recommend a director candidate for consideration by the Nominating and Corporate Governance Committee, the stockholder recommendation should be delivered to the Secretary of the Company at the principal executive offices of the Company, and must include information regarding the candidate and the stockholder making the recommendation.

Our Cybersecurity Committee is generally responsible for assisting the Board in setting accountability of management regarding cybersecurity preparedness, assessing the adequacy of resources and funding to sustain a successful cybersecurity program, providing guidance regarding management's recommendations related to cybersecurity initiatives and providing guidance regarding management's framework for responding to cybersecurity incidents.

Each of Terrell Jones and Kathy Misunas served on the Cybersecurity Committee during 2017. Each of Mr. Jones and Ms. Misunas are independent as currently defined under Nasdaq listing standards. The Cybersecurity Committee met four times during 2017.

Our Steering Committee assists the Board in establishing the Company's long-term strategy and also advises on other strategic matters. The Steering Committee meets from time to time as needed to discuss strategic matters.

Each of Charles Boesenberg, David Cutrer, Chuck Davis, and Mike Finley served on the Compensation Committee of the Board of Directors during 2017. Mr. Boesenberg retired from the Board and all of its committees on which he served in July 2017 and Mr. Cutrer left the Board and all of its committees on which he served in September 2017. None of the members of the Compensation Committee was at any time during the 2017 fiscal year (or at any other time) an officer or employee of the Company. None of our executive officers serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our Board of Directors or Compensation Committee.

Our Board of Directors has combined the roles of Chairman and Chief Executive Officer, who is David Hagan, our Chief Executive Officer, as Chairman of the Board. Our Board has determined that we would be best served by having a Chairman with deep operational and strategic knowledge of our business. Our Board has also appointed Lance Rosenzweig as our Lead Independent Director. Our Board has determined that we would be best served by also having a lead independent director to be responsible for conducting sessions with the independent directors as part of every Board meeting, calling special meetings of the independent directors and chairing all meetings of the independent directors.

Our Board provides risk oversight for our entire company by receiving management presentations, including risk assessments, from all functional areas of our company, and discussing these assessments with management. The Board's overall risk oversight is supplemented by the various committees. The Audit Committee discusses with management and our independent auditors our risk management guidelines and policies, our major financial risk exposures and the steps taken to monitor and control such exposures.

Our Compensation Committee oversees risks related to our compensation programs and discusses with management its annual assessment of our employee compensation policies and programs. Based upon this review, our Compensation Committee believes that any risks arising from such policies and practices are not reasonably likely to have a material adverse effect on the Company in the future. Specifically, we believe that the elements of our compensation program do not encourage unnecessary or excessive risk-taking. Base salaries are fixed in amount and thus do not encourage risk-taking. A significant proportion of the compensation provided to our executives, and a material amount of the compensation provided to other employees, is in the form of long-term equity awards that are important to help further align employee interests with those of our stockholders. We do not believe that these awards encourage unnecessary or excessive risk-taking because the ultimate value of the awards is tied to our stock price, and because awards are subject to long-term vesting schedules to help ensure that employees have significant value tied to long-term stock price performance.

The Cybsecurity Committee discusses with management our cyber risk exposures and processes, and oversees the Company's planning and execution of the cybersecurity plan.

The Company endeavors to improve corporate governance and executive compensation and practices and appreciates the views of its stockholders. As a result of our Board considering feedback received from stockholder outreach and the Company's long-term strategy, our Board recently implemented various changes to our corporate governance practices as summarized below. The Company has received positive feedback from stockholders on these changes.

Our Board desires that the views of the Company's stockholders will be heard by our Board, its committees or individual directors, as applicable, and that appropriate responses will be provided to stockholders on a timely basis. Stockholders wishing to formally communicate with our Board of Directors, any Board committee, the independent directors as a group or any individual director may send communications directly to the Company at Boingo Wireless, Inc., 10960 Wilshire Blvd., 23rd Floor, Los Angeles, California 90024, Attention: Corporate Secretary. All clearly marked written communications, other than unsolicited advertising or promotional materials, are logged and copied, and forwarded to the director(s) to whom the communication was addressed. Please note that the foregoing communication procedure does not apply to (i) stockholder proposals pursuant to Exchange Act Rule 14a-8 and communications made in connection with such proposals, (ii) stockholder proposals and director nominations pursuant to our bylaws or (iii) service of process or any other notice in a legal proceeding.

The Board of Directors met seven times during 2017. Each Board member attended 75% or more of the aggregate of the meetings of the Board and of the committees on which he or she served, held during the period for which such member was a director or committee member. Members of the Board and its committees also consulted informally with management from time to time and acted at various times by written consent without a meeting during 2017. While we do not have a formal policy regarding attendance by members of the Board at our annual meetings of stockholders all directors are encouraged to attend, and all of our directors attended our 2017 annual meeting of stockholders.

The Company has adopted the Boingo Wireless, Inc. Code of Business Conduct and Ethics that applies to all directors, officers and employees. A copy is available on the corporate governance section of our website at www.boingo.com. If the Company makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver in its public filings, as required by law or securities market regulations.

The following table sets forth certain information known to us regarding beneficial ownership of our voting securities as of April 13, 2018 by:

Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission (the "SEC") and generally includes voting or investment power with respect to securities. Except as noted by footnote, and subject to community property laws where applicable, the persons named in the table below have sole voting and investment power with respect to all shares of Common Stock shown as beneficially owned by them. The table below is based upon information supplied by officers, directors and principal stockholders and Schedules 13G filed with the SEC.

This table lists applicable percentage ownership based on 41,756,449 shares of Common Stock outstanding as of April 13, 2018. Options to purchase shares of our Common Stock that are exercisable within 60 days of April 13, 2018 are deemed to be beneficially owned by the persons holding these options and convertible notes for the purpose of computing percentage ownership of that person, but are not treated as outstanding for the purpose of computing any other person's ownership percentage. Restricted stock units that are expected to vest and settle within 60 days of April 13, 2018 are also

deemed to be beneficially owned for purposes of computing percentage ownership of that person, but are not treated as outstanding for the purpose of computing any other person's ownership percentage.

Section 16(a) of the Exchange Act requires our directors, executive officers, and holders of more than 10% of our Common Stock to file reports regarding their ownership and changes in ownership of our securities with the SEC, and to furnish us with copies of all Section 16(a) reports that they file.

We believe that during the fiscal year ended December 31, 2017, our directors, executive officers, and greater than 10% stockholders complied with all applicable Section 16(a) filing requirements. In making these statements, we have relied upon a review of the copies of Section 16(a) reports furnished to us and the written representations of our directors, executive officers, and greater than 10% stockholders.

As provided by our Audit Committee Charter, our Audit Committee is responsible for reviewing and approving in advance any related party transaction. Neither the Board of Directors nor the Audit Committee has adopted specific policies or guidelines relating to the approval of related party transactions. The members of our Audit Committee determine whether to approve a related party transaction in the exercise of their fiduciary duties as directors.

In addition to the compensation arrangements with directors and named executive officers described elsewhere in this proxy statement, since January 1, 2017, there has not been a transaction or series of related transactions in which we were or are a party involving an amount in excess of $120,000 and in which any director, executive officer, holder of more than 5% of our capital stock, or any member of the immediate family or person sharing the household with any of these individuals (other than tenants or employees), had or will have a direct or indirect material interest.

We have entered into an indemnification agreement with each of our directors and executive officers. The indemnification agreements and our certificate of incorporation and bylaws require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware law.

This compensation discussion and analysis, which reviews and discusses our compensation programs and policies for our 2017 named executive officers should be read together with the compensation tables and related disclosures included below. It contains forward-looking statements that are based on our current plans, considerations, expectations and determinations regarding our compensation decisions and programs.

Fiscal 2017 saw the continuation of a long-term incentive compensation program established by our Compensation Committee in fiscal 2016, which included the grant of the "2016 Three-Year Awards" (as described below). In particular, consistent with that program, no additional equity or other long-term incentives were awarded to our Chief Executive Officer or our Chief Financial Officer during fiscal 2017, and the 2017 equity awards granted to our other named executive officers were structured in a manner substantially similar to the 2016 equity awards, with half of each such award subject to service-based vesting and half of each such award (at target level) subject to the satisfaction of specified performance objectives measured over a two-year performance period. Additionally, our Chief Executive Officer and Chief Financial Officer received no additional equity or other long-term incentive awards for our fiscal 2018 compensation cycle.

Additional highlights for our fiscal 2017 executive compensation programs include the following:

See below in "Elements of Compensation" for more detailed discussion of these components of our fiscal 2017 executive compensation program.

Stock Ownership Guidelines. The Company's stock ownership guidelines reinforce our Board of Directors' belief that executives and members of the Board who believe in the future of the Company should have meaningful equity holdings in the Company. The ownership guidelines provide for a three-year transition period from their adoption in 2016, and will require that our directors hold shares and share equivalents equal in value to three times their annual retainer and that each of our executive officers hold shares and share equivalents equal in value to a multiple of base salary, specifically, six times base salary for our Chief Executive Officer and one times base salary for each of our other

executive officers. For purposes of the stock ownership guidelines, vested RSUs and vested and in-the-money options will be counted toward the applicable requirement. As of the end of 2017, all officers and directors were in compliance with these guidelines.

Anti-Hedging and Anti-Pledging. The Company has a policy that prohibits any hedging or pledging transactions of the Company's securities by the Company's directors and executive officers. This policy does not allow for exceptions or waivers to such prohibitions on hedging and pledging.

As discussed in "Risk Oversight Management" above, the Compensation Committee reviews our compensation programs annually and concluded in 2017 that such programs do not create risks that could be reasonably likely to have a material adverse effect on us.

At our 2017 annual meeting of stockholders, over 58% of our stockholders at the meeting voted "For" a non-binding and voluntarily submitted advisory resolution approving the compensation of our named executive officers, as disclosed in the proxy statement for that meeting. Our Compensation Committee reviewed the results of the 2017 advisory vote and concluded that, notwithstanding the disappointing level of approval obtained, it was appropriate to await the conclusion of the long-term incentive program established in 2016 for our Chief Executive Officer and Chief Financial Officer before deviating from the existing executive compensation program structure.

Historically, our compensation programs have aimed to conserve cash while attracting and retaining executive officers who are highly motivated to grow our business in the long term. As with other growth-oriented companies in the wireless industry and the technology sector generally, we emphasize equity compensation, through a mix of service-based and performance-based restricted stock units ("RSUs"), to align the interests of management and stockholders, which we believe motivates the management team to grow the business in the long term. The Compensation Committee continues to believe that the total cash compensation of our named executive officers (including their base salary plus annual incentive bonus) should generally target the 50^th percentile of our selected peer group and that total direct compensation (total cash compensation plus equity awards) should generally target the 60^th percentile of our selected peer group.

We recognize that our success depends to a great degree on the integrity, knowledge, imagination, skill, diversity and teamwork of our employees. To this end, we designed, and intend to modify as necessary, our compensation and benefits program and philosophy in order to attract, retain and motivate talented, highly qualified and committed executive officers who share our business goals and corporate values. In doing so, we strive to reward achievement of clear, easily measured performance goals that keep our executive officers focused on accomplishing our long-term business objectives, while offering sufficient fixed compensation to remain competitive within our industry and geography. We expect to continue relying on this approach in the future.

Role of the Compensation Committee, Board of Directors and Management in Setting Executive Compensation

In general, our Compensation Committee makes compensation decisions regarding our named executive officers. During 2017, Messrs. Davis and Finley served as Committee members. Messrs. Boesenberg and Cutrer also served as Committee members during 2017 until their respective retirement (Mr. Boesenberg) and resignation (Mr. Cutrer) in July and September 2017, respectively. The Compensation Committee has overall responsibility for overseeing and, together with input from the full Board of Directors as the committee deems appropriate, approving the compensation of our Chief Executive Officer and other executive officers. Mr. Finley currently serves as Chair of our Compensation Committee.

We anticipate that our Chief Executive Officer will continue to make recommendations to our Compensation Committee regarding compensation for other executive officers. However, while our Compensation Committee will consider our Chief Executive Officer's recommendations, it need not adopt these recommendations and may adjust them as it deems appropriate together with input from the full Board of Directors. The Committee has authority to approve all compensation decisions regarding our executive officers, although our Board of Directors also retains concurrent authority. The Committee may from time to time refer matters to the entire Board of Directors in order to obtain input from other directors prior to making a decision and, if appropriate, may submit matters for approval by the full Board of Directors. Other executive officers, including our Chief Financial Officer and our Senior Vice President Human Resources, participate in Compensation Committee meetings from time to time, primarily to present information to the Committee.

Our Compensation Committee has the authority to engage the services of outside consultants and advisors to assist it in making decisions regarding our executive compensation programs. The Croner Company has been retained by our Compensation Committee since 2014 to advise the Committee regarding the compensation of our executive officers and non-employee directors. The Compensation Committee believes that The Croner Company's deep expertise in the technology industry provides the Committee with relevant and targeted advice.

To assist the Compensation Committee in evaluating the different components of compensation to be paid to our named executive officers, the Compensation Committee relies on compensation data from a group of peer companies developed with the assistance of The Croner Company. The direction of the Compensation Committee in setting a peer group for 2017 was to include companies within 40% to 250% of the Company's revenue and with a market cap between 25% and 400% of the Company's then-current market cap, with similar or relevant business models and technology and communications companies located in California. For 2017 compensation decisions, the Compensation Committee relied on the following peer group of companies:

•

8x8, Inc.

•

Limelight Networks, Inc.

•

California Amplifier Incorporated

•

LogMeIn, Inc.

•

Exar Corporation

•

Lumos Networks Corp.

•

Global Eagle Entertainment Inc.

•

MaxLinear, Inc.

•

GoGo, Inc.

•

Numerex Corp.

•

GTT Communications, Inc.

•

Orbcomm

•

Inseego Corp. (formerly Novatel Wireless, Inc.)

•

Spok Holdings, Inc.

•

Inteliquent, Inc.

•

Synchronoss Technologies, Inc.

•

iPass Inc.

•

Telenav, Inc.

•

Jive Software, Inc.

•

Vocera Communications

•

KVH Industries, Inc.

The compensation data from the peer group of companies developed with The Croner Company is used in evaluating our executive compensation program. Our Compensation Committee previously made the decision that the total cash compensation of our named executive officers (including their base salary plus annual incentive target bonus) should generally target the 50^th percentile of our selected peer group and that total direct compensation (total cash compensation plus the grant date value of annual equity awards) should generally target the 60^th percentile of our selected peer group compensation data. Our Compensation Committee continued to work with these target levels for fiscal 2017 compensation decisions, although it recognized that its determination in fiscal 2016 to grant equity awards to our Chief Executive Officer and Chief Financial Officer designed to cover fiscal 2016 through fiscal 2018 result in variances from the total direct compensation target for each officer with respect to each fiscal year in that period.

The weight of each of these components has not to date been determined by any particular formula, although our overall mix of total compensation has historically emphasized and continues to emphasize equity-based awards for their long-term incentive and retention value. The specific mix of components has been and will continue to be within the discretion and business judgment of our Board of Directors and the Compensation Committee, which have placed greater emphasis on the dynamics within and strategic direction of the Company and to considerations specific to the individual holding a particular executive position than on general market data.

The following table provides a breakdown for 2017 target compensation for our named executive officers between fixed and variable compensation, based upon the compensation components required to be presented in the Summary Compensation Table (on page 27 herein). Fixed compensation is comprised of annual base salary and service-based equity awards, as it does not vary based on the Company's performance, whereas variable compensation is comprised of annual cash incentive bonuses and performance-based awards, as the value of both components is inherently tied to the Company's performance. Because the value of the equity awards granted to Messrs. Hagan and Hovenier in 2016 appeared in the Summary Compensation Table for 2016, the proportion of their variable compensation shown below for 2017 fails to reflect the 2017 incentive impact of those awards in the Variable Compensation column below.

We provide a base salary to our named executive officers to compensate them for services rendered on a day-to-day basis during the year and to provide sufficient fixed cash compensation to allow them to focus on their ongoing responsibilities. The base salaries of all executive officers are reviewed annually and adjusted when necessary to reflect individual roles and performance as well as market conditions. In connection with the Compensation Committee's annual review process in January 2017, the base salaries of our named executive officers was increased for 2017 by approximately 3% as part of a Company-wide merit increase (which brings our named executive officers to 104% (on average) of the 50^th percentile). The actual base salary increases that our named executive officers received are as follows: Mr. Hagan's base salary was increased from $515,000 to approximately $530,000; Mr. Hovenier's base salary was increased from approximately $337,000 to approximately $348,000; Ms. Callahan's base salary was increased from approximately $284,000 to approximately $292,000; Dr. Peterson's base salary was increased from $297,000 to approximately $306,000; and Mr. Tracey's base salary was increased from approximately $276,000 to approximately $284,000.

We use annual cash incentive bonuses to reward our named executive officers for the achievement of Company performance goals. Each year, we adopt new corporate financial objectives under our management incentive compensation plan to motivate and reward our senior executives, including our named executive officers, to attain specific short-term performance objectives that, in turn, further our long-term business objectives. These objectives are based upon corporate targets, rather than individual objectives. In setting target payout levels under our management incentive compensation plan, our Compensation Committee considered historical payouts, the total cost to the Company should performance objectives be achieved and our retention needs. The Compensation Committee retains discretion to reduce or eliminate payment under our management incentive compensation plan.

For 2017, in connection with our continued efforts to respond to input we received from our stockholders, we increased the focus of our management incentive plan on non-revenue objectives as well as annual performance. The performance goals under our management incentive compensation plan had previously included two corporate objectives, revenue (determined on a quarterly basis) and Adjusted EBITDA (determined on an annual basis); however, for 2017 we also added an annual free cash flow target objective. For each goal in 2017, we established a threshold and a maximum achievement level, as well as a weighting as a proportion of the total bonus objective. The revenue and Adjusted EBITDA objectives were originally selected based on the desire to strongly encourage responsible revenue growth with profitability during the year as well as continued focus on our long-term strategy of monetizing our high-density wireless networks, including DAS and Wi-Fi networks. For 2017, our Compensation Committee determined it appropriate to include a free cash flow target, weighted at 10% of total target opportunity, in order to increase management's focus on non-revenue objectives as well as annual performance, and further determined it appropriate to equally weight revenue at 45% and Adjusted EBITDA at 45%. This change resulted in the relative weighting of annual objectives increasing to 55% of total target opportunity, compared to 20% in fiscal 2016, and of quarterly objectives decreasing to 45%, compared to 80% in fiscal 2016.

For the 2017 cash bonuses, achievement of each financial objective at target equates to 100% of the bonus payout. With respect to the revenue objective, underachievement at the floor of 90% of the financial target results in a bonus payout of 50% for the objective and overachievement at 110% results in a maximum bonus payout of 150% for the objective. For both the Adjusted EBITDA and free cash flow objectives, underachievement at the floor of 70% of the financial target results in 50% of the bonus payout for the objective and overachievement at 120% results in a maximum bonus payout of 150% for the objective. Below the floor levels of each of the financial targets, there is no bonus payout. In the event of any under or overachievement, straight line interpolation is applied from target levels.

Target bonuses for our named executive officers under the 2017 plan were as follows:

The relative weighting of each financial objective, together with 2017 target levels, actual achievement, and the percentage of target achieved, is as follows:


Applicable Quarter	Relative Weighting		Target Level Achievement		Actual Achievement	% of Target Achieved
1		9	%	$	41,567,000	$	44,333,000	107	%
2		10	%	$	44,948,000	$	49,033,000	109	%
3		12	%	$	48,612,000	$	53,655,000	110	%
4		14	%	$	54,405,000	$	57,348,000	105	%

In February 2018, our Compensation Committee determined the achievement of the financial objectives applicable under the management incentive compensation plan for 2017 at an aggregate level of 143%, resulting in bonus payouts for fiscal 2017 as follows: Mr. Hagan—$759,111; Mr. Hovenier—$373,027; Ms. Callahan—$230,132; Dr. Peterson—$240,778; and Mr. Tracey—$223,619. The portion of these amounts attributable to revenue were paid on a quarterly basis; any remaining unpaid amounts, including the portion attributable to Adjusted EBITDA and free cash flow, were paid following the end of the calendar year.

We believe that equity-based awards encourage our named executive officers to focus on the long-term performance of our business. Our Compensation Committee grants equity awards to executives and other employees in order to enable them to participate in the long-term appreciation of our stock price. Additionally, we believe our equity awards provide an important retention tool for our named executive officers, as they are subject to multi-year vesting.

While we have in the past granted stock options, our current grant practices utilize service-based and performance-based RSUs. We believe that RSUs are the appropriate form of long-term incentive award for our Company in the current competitive conditions facing the wireless industry in which we compete for executive talent, allowing us to both retain current employees and attract new talent, as well as limit the dilution to our stockholders that a stock option program would impose. For named executive officers, we generally determine the number of RSUs to be granted by dividing the grant value approved by our Compensation Committee by the average trading price for the five consecutive days preceding the date of grant.

Our Compensation Committee made significant changes in early 2016 to our long-term equity incentive program for our Chief Executive Officer and our Chief Financial Officer. Messrs. Hagan and Hovenier were each granted in 2016 RSUs that encompassed the aggregate target award value that they might otherwise have been granted in annual installments over each of 2016, 2017 and 2018.⁽²⁾ We refer to each of these awards as a "2016 Three-Year Award." Neither officer has been granted any additional equity or long-term incentive awards since the 2016 Three-Year Awards. Our named executive officers other than our Chief Executive Officer and Chief Financial Officer, on the other hand, have continued to receive RSUs on an annual basis, 50% of the grant value of which is subject to service-based vesting and 50% of the grant value (at target level) of which is subject to satisfaction of specified performance objectives measured over a two-year performance period.

The RSUs granted to all of our named executive officers in 2016, including the 2016 Three-Year Awards granted to Messrs. Hagan and Hovenier, were subject to satisfaction of specified service-based and performance-based conditions. These awards were equally apportioned between service-based RSUs (50% of the grant value) and performance-based RSUs (50% of the grant value based upon at-target performance). The performance-based RSUs were subject to two equally-weighted performance objectives: 50% of the at-target value was based upon achieving average revenue growth of 15% over a two-year period ending on December 31, 2017, as compared with revenue in the year ending on December 31, 2015, and 50% was based upon an Adjusted EBITDA margin target of 25%, measured at the end of 2017. The performance objectives were subject to under- or over- achievement on a sliding scale, with a threshold of 50% of the target number of RSUs (for average revenue growth of 10% and an Adjusted EBITDA margin target of 24%) and a maximum of 150% of the target number of RSUs (for average revenue growth of 20% and an Adjusted EBITDA margin target of 26%), with straight-line interpolation applied between performance increments.

In February 2018, our Compensation Committee determined that the average revenue growth over the two-year period ending on December 31, 2017 was 21.2% and the Adjusted EBITDA margin was 33.7%, resulting in achievement of the 2016 performance-based RSUs at the maximum level, or 150% of the target objective. As a result, our named executive officers will be eligible to vest in the following total number of RSUs: Mr. Hagan: 877,792; Mr. Hovenier: 585,195; Ms. Callahan: 50,016; Dr. Peterson: 50,016; and Mr. Tracey: 37,512. For Mr. Hagan and Mr. Hovenier, such RSUs will vest on February 1, 2019, subject to each officer remaining in service with us through that date. For Ms. Callahan, Dr. Peterson and Mr. Tracey, 66²/3% of such RSUs vested on the date achievement was determined, and the remainder will vest in four equal quarterly installments beginning on May 1, 2018, subject to the executive officer's continued service through each vesting date.

2017 Equity Awards. In early 2017, and in continuance of the long-term incentive program implemented in 2016, our named executive officers other than Messrs. Hagan and Hovenier were

granted RSUs, with 50% of the aggregate grant value in service-based RSUs and 50% in performance-based RSUs (at-target). As with the 2016 performance-based RSUs, the performance-based RSUs granted to Ms. Callahan, Dr. Peterson and Mr. Tracey are subject to a two-year performance period as well as both an Adjusted EBITDA margin objective and a revenue growth objective. The 2017 service-based RSUs granted to Ms. Callahan, Dr. Peterson and Mr. Tracey began vesting in 12 equal quarterly installments on May 1, 2017, subject to each executive officer's continued service through each vesting date, and the 2017 performance-based RSUs will vest as to 66²/3% of the RSUs that become eligible to vest based on performance on the date in 2019 on which our Compensation Committee determines the achievement, an additional 8¹/3% of such RSUS will vest on May 1, 2019, and an additional 8¹/3% of such RSUs will vest upon the executive officer's completion of an additional quarter of continuous service thereafter.

The actual number of 2017 service-based RSUs and 2017 performance-based RSUs (at target) granted to each of our named executive officers other than Messrs. Hagan and Hovenier is as follows:

In addition, our Compensation Committee in 2017 amended certain outstanding awards, including RSUs held by our named executive officers, to permit share withholding from the award to cover the tax withholding in excess of the minimum statutory withholding rate in response to recent changes to accounting guidance, and certain stock options nearing the end of their 10-year term to add a net exercisability feature. We do not have, nor do we plan to establish, any program, plan or practice to time equity award grants in coordination with releasing material non-public information, nor do we have any established grant schedule.

Our Board of Directors believes that it is necessary to offer senior members of our executive team severance benefits to ensure that they remain focused on executing our strategic plans, including in the event of a proposed or actual acquisition. We have entered into employment agreements with our named executive officers to provide them with additional severance benefits upon an involuntary termination of employment under specified circumstances prior to and following a change of control. The terms of these agreements are described below in "Severance or Employment Agreements."

Additionally, the 2016 RSUs granted to Messrs. Hagan, Hovenier and Tracey, Dr. Peterson and Ms. Callahan as well as the 2017 RSUs granted to Mr. Tracey, Dr. Peterson and Ms. Callahan provide that if the officer were to be involuntarily terminated outside the change of control context, then they would be treated as vested in a number of shares underlying the award equal to the sum of the number of shares applying a monthly pro-rata vesting over the three-year overall vesting schedule (with the performance-based RSUs determined at 100% of target if before the date performance has been determined to be achieved, and at the actual level of achievement if after such date), plus in Mr. Hagan's case an additional 24 months of vesting, in Mr. Hovenier's case an additional 12 months of vesting or in Ms. Callahan's, Dr. Peterson's or Mr. Tracey's case, an additional 9 months of vesting. Upon an involuntary termination in connection with a change of control, each officer would be entitled to full vesting of these awards, with achievement of the performance-based award deemed to be at-target if the transaction occurred prior to the end of the two-year performance period.

We do not provide any significant perquisites or other personal benefits to our named executive officers.

We provide the following benefits, which we believe are typical of the companies with which we compete for employees, to our named executive officers on the same basis provided to all of our employees:

Section 162(m) of the Code limits deductibility of certain compensation to $1.0 million per year for the Chief Executive Officer and certain other executive officers. Prior to changes in tax law taking effect in 2018, there was an exception to the $1.0 million limitation for performance-based compensation, including stock options, meeting certain requirements. Historically, the stock options we have granted to named executive officers were designed to qualify as performance-based compensation for purposes of Section 162(m), as well as a portion of our performance-based RSUs. However, to maintain flexibility in compensating our executive officers in a manner designed to achieve our strategic goals, contractual commitments and such other factors as our Compensation Committee considered in its judgment to be appropriate, our Compensation Committee does not have a policy requiring all compensation to be deductible.

The exemption from the Section 162(m) deduction limit for performance-based compensation has been repealed, effective for taxable years beginning after December 31, 2017, such that compensation paid to our Chief Executive Officer and certain other executive officers in excess of $1.0 million will not be deductible unless it qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017.

The Compensation Committee has reviewed and discussed the foregoing Compensation Discussion and Analysis with management and, based on such review and discussions, the Compensation Committee has recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement.

The following table provides information regarding the compensation of our "principal executive officer," our "principal financial officer," and our next three most highly compensated executive officers during the 2017 fiscal year. We refer to these individuals as our "named executive officers."

(1): The amounts in this column represent the aggregate grant date fair value of stock awards granted to the officer in the applicable fiscal year computed in accordance with FASB ASC Topic 718. See Notes 2 and 14 of the notes to our audited consolidated financial statements included in our Annual Report on Form 10-K for a discussion of the assumptions made by the Company in determining the grant date fair value of its equity awards. In accordance with SEC rules, the grant date fair value of any award subject to a performance condition is based on the probable outcome of the performance conditions. In 2017, each named executive officer other than Messrs. Hagan and Hovenier was granted both performance-based RSUs, the vesting of which is contingent upon the Company's achievement of the specified revenue growth and EBITDA margin targets, and service-based RSUs, as described in greater detail in the "Long-Term Equity Incentive Award Program" section of the "Compensation Discussion and Analysis" beginning on page 24. The grant date fair value of the performance-based RSUs included in the "stock awards" column above assumes the RSUs will become eligible to vest at their "target" level (100%), which the Company determined was the probable outcome for the awards at the time of grant, and is 50% of the total grant date fair value reflected in the "stock awards" column, with the other 50% of the total grant date fair value attributable to the service-based RSUs. The grant date fair value of the performance-based RSUs assuming achievement at the maximum level (150%) is $226,653.

(1): Each named executive officer was granted a non-equity incentive plan award pursuant to our 2017 management incentive compensation plan which is discussed in greater detail in the "Annual Cash Incentive Bonuses" section of the "Compensation Discussion and Analysis," beginning on page 23. The amounts show in the "target" column reflect the target payout under the plan. The target amount is equal to 100% of Mr. Hagan's annual base salary, 75% of Mr. Hovenier's annual base salary, and 55% of Ms. Callahan's, Dr. Peterson's, and Mr. Tracey's annual base salary. The amounts shown in the "minimum" column reflect the minimum payout of 50% of the target bonus amount if 90% of the revenue, 70% of the Adjusted EBITDA and 70% of the free cash flow targets are achieved. The amounts shown in the "maximum" column reflect the maximum payout of 150% of the target bonus amount if 110% of the revenue, 120% of the Adjusted EBITDA and 120% of the free cash flow targets are achieved. The actual amounts paid to each named executive officer are shown in the Summary Compensation Table on page 27.
(2): Each of our named executive officers other than Messrs. Hagan and Hovenier was granted performance-based RSUs under our 2011 Equity Incentive Plan, the vesting of 50% of which is related to the Company's 2017 and 2018 revenue growth and the remaining 50% of which is related to the Company's EBITDA margin at the end of 2018, as discussed in greater detail in the "Long-Term Equity Incentive Award Program" section of the "Compensation Discussion and Analysis," beginning on page 24. The number of RSUs reflected in the table above as the "threshold" amount represents the minimum number of RSUs that will be eligible to vest based on satisfaction of the one year service-based component with the Company following the performance period if either the revenue or the EBITDA margin targets are met at their minimum achievement level. The number of RSUs reflected in the table above as the "target" requires full achievement of both the revenue and EBITDA margin targets and will only vest based on satisfaction of the service-based component with the Company following the performance period. The number of RSUs reflected in the table above as the "maximum" requires overachievement of both the revenue and Adjusted EBITDA margin targets and will only vest based on satisfaction of the service-based component with the Company following the performance period.
(3): The amounts in this column represent the aggregate grant date fair value of stock awards granted to the officer in the applicable fiscal year computed in accordance with FASB ASC Topic 718.

(3): Vesting of the shares underlying the RSU award was originally contingent upon certain performance-based metrics during the 2015 fiscal year. The shares underlying the RSU for which the performance metric was achieved are eligible to vest based on continued service to the Company. 33¹/3% of the shares vested on the initial vesting date and, pursuant to a vesting extension agreement entered into with each of Messrs. Hagan and Hovenier on February 1, 2016, the remaining shares underlying the award will vest in full on March 1, 2018, subject to their continued service to the Company through such date.
(4): Shares underlying the RSU award will vest in full on the initial vesting date, subject to continued service to the Company through such date.
(5): Vesting of the shares underlying the performance-based RSU award was originally contingent upon certain performance-based metrics over a two-year performance period ending on December 31, 2017. Following a determination that achievement was at the maximum level on February 22, 2018, the RSUs are eligible to vest in full on the initial vesting date, subject to continued service through such date.
(6): Shares underlying the RSU award vest in a series of twelve successive equal quarterly installments commencing on the initial vesting date, subject to continued service to the Company through each vesting date.
(7): Vesting of the shares underlying the RSU award was originally contingent upon certain performance-based metrics during the 2015 fiscal year. The shares underlying the RSU award for which the performance metric was achieved are eligible to vest based on continued service to the Company, with 33¹/3% of such shares vesting on the initial vesting date, and with respect to the balance in a series of eight successive equal quarterly installments thereafter.
(8): Vesting of the shares underlying the performance-based RSU award was originally contingent upon certain performance-based metrics over a two-year performance period ending on December 31, 2017. 66²/3% of the shares underlying the RSU award vested on February 22, 2018, following a determination that achievement was at the maximum level. An additional 1/12^th of such shares will vest on May 1, 2018, and an additional 1/12^th of such shares will vest quarterly thereafter, subject to continued service to the Company through each vesting date.
(9): Vesting of the shares underlying the performance-based RSU award is contingent upon achievement of both a revenue growth metric and the Company's Adjusted EBITDA margin over a two-year performance period ending on December 31, 2018, as well as continued service through the date performance is determined to have been achieved by the Company. 66²/3% of the shares underlying the RSU award for which performance is determined to have been achieved will vest on such date of determination, an additional 1/12^th of such shares will vest on May 1, 2018, and an additional 1/12^th of such shares will vest quarterly thereafter, subject to continued service to the Company through each vesting date. The number of shares in the table above and the corresponding value of such shares reflects target performance.

The following table shows the number of shares acquired upon exercise of options by each named executive officer during the 2017 fiscal year and the number of restricted stock units held by each named executive officer that vested during the 2017 fiscal year.

We do not provide a pension plan for our employees, and no named executive officers participated in a nonqualified deferred compensation plan during 2017.

Please see "Severance or Employment Agreements" below for a description of the severance arrangements for our named executive officers.

The following table describes the potential payments and benefits for each of our named executive officers under their employment agreements upon an involuntary termination, as if each officer's employment terminated as of December 31, 2017.

(1): The value of vesting of RSUs shown above assumes that each executive's qualifying termination of employment and change of control (if applicable) occurred on December 31, 2017, and was calculated by multiplying the number of unvested RSUs that will accelerate by the fair market value of our common stock on December 29, 2017 ($22.50).
(2): For the 2016 RSUs, includes that number of RSUs underlying the award equal to the sum of the number of RSUs applying a monthly pro-rata vesting over the 3-year overall vesting schedule (with the performance-based RSUs determined at maximum), plus in Mr. Hagan's case an additional 24 months of vesting, in Mr. Hovenier's case an additional 12 months of vesting and, in Ms. Callahan's, Dr. Peterson's or Mr. Tracey's case, an additional 9 months of vesting. For the 2017 RSUs granted to each of Ms. Callahan, Dr. Peterson and Mr. Tracey, includes that number of RSUs underlying the award equal to the sum of the number of RSUs applying a monthly pro-rata vesting over the 36 month period commencing on February 1, 2017 plus an additional 9 months of vesting (with the performance-based RSUs at 100% of target).

On April 11, 2011, we entered into an employment agreement with Mr. Hagan that provides that if Mr. Hagan's employment is terminated without cause or should Mr. Hagan resign his employment for good reason prior to, or more than 12 months after, a change of control, Mr. Hagan is entitled to 12 months of base salary, annual target bonus, 12 months of continued health benefits, and 24 months of vesting credit under his outstanding equity awards. If Mr. Hagan's employment is terminated without cause or should Mr. Hagan resign his employment for good reason within 12 months following a change of control, Mr. Hagan is entitled to 12 months of base salary, annual target bonus, 12 months of continued health benefits, and full vesting of his outstanding equity awards.

We entered into an employment agreement with Mr. Hovenier in April 2013 after he was promoted as our Chief Financial Officer. Under this agreement, if Mr. Hovenier's employment is terminated without cause or should Mr. Hovenier resign his employment for good reason prior to, or more than 12 months after, a change in control, Mr. Hovenier is entitled to 12 months of base salary, a pro rata payment of his annual target bonus, 12 months of continued health benefits, and 12 months of vesting credit under his outstanding equity awards. If Mr. Hovenier's employment is terminated without cause or should Mr. Hovenier resign his employment for good reason within 12 months following a change in control, Mr. Hovenier is entitled to 12 months of base salary, annual target bonus, 12 months of continued health benefits, and full vesting of his outstanding equity awards.

We entered into an employment agreement with Ms. Callahan in January 2013 after she was promoted to our Senior Vice President of Marketing and Sales. Under this agreement, if Ms. Callahan's employment is terminated without cause or should Ms. Callahan resign her employment for good reason prior to, or more than 12 months after, a change in control, Ms. Callahan is entitled to 9 months of base salary, 9 months of continued health benefits, and 9 months of vesting credit under her outstanding equity awards. If Ms. Callahan's employment is terminated without cause or should Ms. Callahan resign her employment for good reason within 12 months following a change in control, Ms. Callahan is entitled to 12 months of base salary, annual target bonus, 12 months of continued health benefits, and full vesting of her outstanding equity awards.

We entered into an employment agreement with Dr. Peterson in January 2013 after he was promoted to our Senior Vice President of Engineering. Under this agreement, if Dr. Peterson's employment is terminated without cause or should Dr. Peterson resign his employment for good reason prior to, or more than 12 months after, a change in control, Dr. Peterson is entitled to 9 months of base salary, 9 months of continued health benefits, and 9 months of vesting credit under his outstanding equity awards. If Dr. Peterson's employment is terminated without cause or should Dr. Peterson resign his employment for good reason within 12 months following a change in control, Dr. Peterson is entitled to 12 months of base salary, annual target bonus, 12 months of continued health benefits, and full vesting of his outstanding equity awards.

We entered into an employment agreement with Mr. Tracey in September 2011 after he was promoted as our Senior Vice President of Operations. Under this agreement, if Mr. Tracey's employment is terminated without cause or should Mr. Tracey resign his employment for good reason prior to, or more than 12 months after, a change in control, Mr. Tracey is entitled to 9 months of base salary, 9 months of continued health benefits, and 9 months of vesting credit under his outstanding equity awards. If Mr. Tracey's employment is terminated without cause or should Mr. Tracey resign his employment for good reason within 12 months following a change in control, Mr. Tracey is entitled to 12 months of base salary, annual target bonus, 12 months of continued health benefits, and full vesting of his outstanding equity awards.

As required by the Dodd-Frank Act and SEC rules, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of David Hagan, our Chief Executive Officer as of December 31, 2017:

Based on this information, the ratio of the annual total compensation of Mr. Hagan to the median of the annual total compensation of our employees was 10.8:1.

The above ratio is appropriately viewed as an estimate. To identify our "median employee" for purposes of this disclosure, we reviewed the salary, stock awards, non-equity incentive plan compensation, and matching contributions made under our 401(k) plan during 2017 for all of our employees as of December 31, 2017 for the period from January 1, 2017 through December 31, 2017. Non-U.S. employees were excluded as they constituted less than 5% of our workforce. As of December 31, 2017, we had 334 employees, including 9 employees in Brazil, 3 employees in the United Arab Emirates, and 1 employee in the United Kingdom. No cost-of-living or other adjustments were made. Once we identified our "median employee" using the methodology described above, we determined that employee's annual total compensation in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K for purposes of calculating the required pay ratio.

Non-employee directors of the Company are eligible for paid compensation for services provided as a director. Each member of our Board of Directors who was not an employee was paid an annual retainer for 2017 service of $35,000. In addition, Board members were paid additional annual retainer amounts in 2017 for specified service, as follows:

In February 2018, our Board of Directors approved the following increases in the cash compensation paid to our non-employee directors, effective as of January 1, 2018:

The non-employee members of our Board of Directors are also eligible for reimbursement of reasonable out-of-pocket travel expenses incurred in attending Board and committee meetings.

Our equity compensation program for non-employee directors provides for the grant of restricted stock units ("RSUs") and is comprised of both an initial equity award upon joining our Board of Directors and annual equity awards in connection with each annual meeting of our stockholders.

The following table sets forth information about the compensation of each person who served as a director during the 2017 fiscal year, other than a director who also served as a named executive officer.

(1): The amounts in this column represent the aggregate grant date fair value of stock awards granted to the non-employee director in the applicable fiscal year computed in accordance with FASB ASC Topic 718. See Notes 2 and 14 of the notes to our audited consolidated financial statements included in our Annual Report on Form 10-K for a discussion of the assumptions made by the Company in determining the grant date fair value of its equity awards.
(2): As of December 31, 2017, the above-listed non-employee directors held outstanding RSUs under which the following number of shares of our common stock are issuable: Maury Austin—24,616; Chuck Davis—7,164; Mike Finley—7,164; Terrell Jones—7,164; Kathy Misunas—22,385; and Lance Rosenzweig—15,202.
(3): As of December 31, 2017, Chuck Davis held outstanding vested options to purchase 36,000 shares of our common stock. These options were granted prior to 2013, when the equity component of our non-employee director compensation program provided for options rather than RSUs.
(4): Mr. Boesenberg retired from our Board of Directors in July 2017.
(5): Mr. Cutrer left our Board of Directors in September 2017.

In January 2016, our Compensation Committee adopted stock ownership guidelines for our non-employee directors and our named executive officers. The ownership guidelines provide for a three year transition period from their adoption, and will require that our non-employee directors hold shares and share equivalents equal in value to three times their annual retainer. For purposes of the

stock ownership guidelines, vested RSUs and vested and in-the-money options will be counted toward the applicable requirement. All of our non-employee directors are in compliance with these new guidelines.

We have two equity compensation plans under which shares of Common Stock are authorized for issuance to eligible employees, directors, and consultants: (i) the Amended and Restated 2001 Stock Incentive Plan, or 2001 Plan; and (ii) the 2011 Equity Incentive Plan, or Incentive Plan. The following table provides certain information with respect to each of our equity compensation plans in effect as of December 31, 2017:

In March 2011, our Board of Directors and stockholders approved the Incentive Plan. The Incentive Plan became effective on May 3, 2011 upon the completion of our initial public offering. The Incentive Plan provides for the grant of incentive and non-statutory stock options, stock appreciation rights, restricted shares of our common stock, restricted stock units, and performance cash awards. The number of shares of common stock reserved for issuance under the Incentive Plan automatically increases on January 1 of each calendar year through 2018 by an amount equal to the least of (a) 4.5% of the total number of shares of common stock then outstanding, (b) 3,000,000 shares of common stock or (c) a lower number determined by our Board of Directors. As of December 31, 2017, options to purchase 1,128,308 shares of common stock and RSUs covering 3,957,550 shares of common stock were outstanding under the Incentive Plan.

Our Board of Directors and stockholders approved the 2001 Plan. The 2001 Plan was terminated following the completion of our initial public offering, and no further awards will be made under that plan. Options outstanding under the 2001 Plan will continue to be governed by their existing terms. As of December 31, 2017, options to purchase 154,699 shares of common stock were outstanding under the 2001 Plan.

The following table represents aggregate fees billed or to be billed to the Company for the fiscal years ended December 31, 2017 and December 31, 2016 by PricewaterhouseCoopers LLP, our principal accountant.

The Audit Committee's policy is to pre-approve all audit and permissible non-audit services rendered by PricewaterhouseCoopers LLP, our independent registered public accounting firm. The Audit Committee pre- approves specified services in defined categories of audit services, audit- related services and tax services up to specified amounts, as part of the Audit Committee's approval of the scope of the engagement of PricewaterhouseCoopers LLP or on an individual case-by-case basis before PricewaterhouseCoopers LLP is engaged to provide a service. The Audit Committee has determined that the rendering of the services other than audit services by PricewaterhouseCoopers LLP is compatible with maintaining the principal accountant's independence.

The Audit Committee of the Board of Directors consists of the three non-employee directors named below and operates under a written charter adopted by the Board. The Board annually reviews the Nasdaq listing standards' definition of independence for Audit Committee members and has determined that each member of the Audit Committee meets that standard. The Board of Directors has also determined that Maury Austin, Terrell Jones and Lance Rosenzweig each is an audit committee financial expert as described in applicable rules and regulations of the Securities and Exchange Commission.

The principal purpose of the Audit Committee is to assist the Board of Directors in its general oversight of our accounting and financial reporting processes and audits of our financial statements. The Audit Committee is responsible for selecting and engaging our independent auditor and approving the audit and non-audit services to be provided by the independent auditor. The Audit Committee's function is more fully described in its Charter, which the Board adopted and which the Audit Committee reviews on an annual basis.

Our management is responsible for preparing our financial statements and our financial reporting process. PricewaterhouseCoopers LLP, our independent registered public accounting firm, is responsible for performing an independent audit of our consolidated financial statements and expressing an opinion on the conformity of those financial statements with U.S. generally accepted accounting principles as well as performing an audit of the effectiveness of our internal control over financial reporting as of the end of the fiscal year.

The Audit Committee has reviewed and discussed with our management the audited financial statements of the Company included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 ("10-K").

The Audit Committee has also reviewed and discussed with PricewaterhouseCoopers LLP the audited financial statements in the 10-K. In addition, the Audit Committee discussed with PricewaterhouseCoopers LLP those matters required to be discussed by the auditors with the Audit Committee under the rules adopted by the Public Company Accounting Oversight Board (the "PCAOB"), including General Auditing Standards 1301, Communications with Audit Committees. Additionally, PricewaterhouseCoopers LLP provided to the Audit Committee the written disclosures and the letter required by the applicable requirements of the PCAOB regarding the independent accountant's communications with the Audit Committee concerning independence. The Audit Committee also discussed with PricewaterhouseCoopers LLP its independence from the Company and satisfied itself as to the independence of PricewaterhouseCoopers LLP.

Based upon the review and discussions described above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company's 10-K for filing with the Securities and Exchange Commission.

Our Board of Directors currently consists of seven directors divided into three classes, with the terms of office of each class ending in successive years. The term of the directors currently serving in Class I expire on the date of the Annual Meeting.

While our Board of Directors is currently classified, at the 2017 annual meeting of stockholders, our stockholders approved a phased-in declassification of our Board of Directors. Commencing with the Annual Meeting, director nominees who are reelected will be reelected for a term of one year, but directors elected prior to the Annual Meeting will continue to serve the remainder of their terms. Therefore, directors elected in Class I at the Annual Meeting will hold office for one year until the 2019 annual meeting of stockholders. The directors in Class II and Class III will continue in office until their terms expire at the 2019 and 2020 annual meeting of stockholders, respectively, after which they will each be subject to election for a one-year term. Therefore, at the 2019 annual meeting of stockholders, the directors in Class I and Class II will be subject to election for a one-year term. At the 2020 annual meeting of stockholders, all director nominees will be subject to election and such directors elected at the annual meeting of stockholders in 2020 will all be elected for a one-year term. Therefore, after the 2020 annual meeting of stockholders our Board of Directors will no longer be classified. The nominees for director in Class I and the other directors who will continue in office for terms extending beyond the Annual Meeting, their ages as of April 1, 2018, their positions and offices held with the Company are set forth below. Other biographical information for the nominees for director in Class III and the other directors who will continue in office for terms extending beyond the Annual Meeting is set forth in this proxy statement under the heading "Directors, Executive Officers and Corporate Governance—Directors and Executive Officers."

Directors are elected by a majority of the votes cast in an uncontested election of directors. Therefore, in an uncontested election of directors (i.e., an election where the only nominees are those recommended by our Board), each member of our Board will be elected only if the votes cast for the nominee exceed the votes cast against the nominee. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the three nominees named below. However, if you are the beneficial owner of the shares, which means that your shares are held by a brokerage firm, bank, dealer, or other similar organization as your nominee, your shares will not be voted for the election of directors unless you have provided voting instructions to your nominee. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by our current Board of Directors, if any. Each person nominated for election has agreed to serve if elected. We have no reason to believe that any nominee will be unable to serve.

We have also implemented a majority voting policy for director resignations, applicable if an incumbent director nominee receives less than a majority of votes cast in an uncontested election. Each director nominated for reelection must tender his or her written irrevocable, conditional resignation to the Chairman of the Board that will be effective only upon both (i) the failure to receive the required vote at the Annual Meeting and (ii) Board acceptance of such resignation. If a director nominee fails to receive the required vote for reelection, our Nominating and Corporate Governance Committee (other than such director) will act on an expedited basis to determine whether to accept the director's irrevocable, conditional resignation, and it will submit such recommendation for prompt consideration by the Board. The Nominating and Corporate Governance Committee and members of the Board (other than such director) may consider any factors they deem relevant in deciding whether to accept a director's resignation. This policy does not apply in circumstances involving contested director elections.

The nominees recommended by your Board have consented to serving as nominees for election to the Board, to being named in this proxy statement and to serving as members of the Board if elected

by Boingo's stockholders. As of the date of this proxy statement, we have no reason to believe that any nominee will be unable or unwilling to serve if elected as a director. However, if for any reason a nominee becomes unable to serve or for good cause will not serve if elected, the Board upon the recommendation of its Nominating and Corporate Governance Committee may designate substitute nominees, in which event the shares represented by proxies returned to us will be voted for such substitute nominees. If any substitute nominees are so designated, we will file an amended proxy statement that, as applicable, identifies the substitute nominees, discloses that such nominees have consented to being named in the amended proxy statement and to serve as directors if elected, and includes certain biographical and other information about such nominees required by the applicable rules promulgated by the SEC.

NOMINEES FOR CLASS I CONTINUING IN OFFICE UNTIL THE 2018 ANNUAL MEETING OF STOCKHOLDERS

Messrs. Hagan's and Rosenzweig's biographies are set forth in this proxy statement under the heading "Directors, Executive Officers and Corporate Governance—Directors and Executive Officers."

We have determined that each of these director nominees possesses the requisite communication skills, personal integrity, business judgment, ability to make independent analytical inquiries, and willingness to devote adequate time and effort necessary to serve as an effective member of the Board. Other specific experiences, qualifications, attributes or skills of nominees that contributed to our conclusion that the nominees should serve as directors are noted in their biographies.

DIRECTORS IN CLASS II CONTINUING IN OFFICE UNTIL THE 2019 ANNUAL MEETING OF STOCKHOLDERS

DIRECTORS IN CLASS III CONTINUING IN OFFICE UNTIL THE 2020 ANNUAL MEETING OF STOCKHOLDERS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
A VOTE "FOR" THE NOMINEES FOR DIRECTORS IN CLASS I:
DAVID HAGAN AND LANCE ROSENZWEIG.

PROPOSAL 2
RATIFICATION OF APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS OUR
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2018

The Audit Committee of the Board of Directors has selected PricewaterhouseCoopers LLP, independent registered public accounting firm, as our independent auditors for the fiscal year ending December 31, 2018 and has further directed that management submit the selection of independent auditors for ratification by the stockholders at the Annual Meeting.

Neither our bylaws nor other governing documents or law require stockholder ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm. However, the Board is submitting the selection of PricewaterhouseCoopers LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders. Representatives of PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting, and will have the opportunity to make statements if they desire to do so and to respond to appropriate questions.

The affirmative vote of the holders of a majority of the votes cast at the Annual Meeting will be required to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018. Abstentions will be counted as present for purposes of determining the presence of a quorum, but will not be considered as votes cast for or against this proposal, and will therefore have no effect on the outcome of the vote. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
A VOTE "FOR" THE RATIFICATION THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP
AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2018.

PROPOSAL 3
ADVISORY APPROVAL OF THE COMPANY'S EXECUTIVE COMPENSATION
FOR THE YEAR ENDED DECEMBER 31, 2017

In accordance with SEC rules, stockholders are being asked to approve, on a non-binding advisory basis, the compensation of our named executive officers for the year ended December 31, 2017 as disclosed in this proxy statement. This is commonly referred to as a "Say on Pay" proposal. Historically, the Company has held an advisory vote on executive compensation every three years; however, in 2017, our Board of Directors determined to voluntarily conduct an advisory vote despite the fact that the last advisory vote was held in 2015. Our Board of Directors has determined to conduct an additional advisory vote this year as well, as the Board is recommending a frequency of "every year" for the advisory vote on executive compensation, as further described in "Proposal 4—Advisory Vote on the Frequency of the Advisory Vote on the Company's Executive Compensation of One, Two or Three Years." This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this Proxy Statement.

As described further in the "Executive Compensation" section of this Proxy Statement, beginning on page 19, including the "Compensation Discussion and Analysis" and the related tables and narrative, the primary goals of our compensation programs are to fairly compensate employees, attract and retain highly qualified employees, motivate the performance of our employees towards, and reward the achievement of, clearly defined corporate goals, and align our employees' long-term interests with those of our stockholders. We believe our compensation programs reflect a pay-for-performance philosophy that links potential significant compensatory rewards to achievement of corporate operating goals and increase in stockholder value.

This Say on Pay vote is advisory, and therefore not binding on our Compensation Committee or Board of Directors. Our Board of Directors and our Compensation Committee value the opinions of our stockholders, however, and will carefully review and consider the voting results when evaluating our executive compensation programs.

If a quorum is present, the proposal to approve, on an advisory basis, the compensation of the Company's named executive officers requires a "For" vote from the majority the votes cast at the Annual Meeting. Abstentions and broker non-votes will each be counted as present for purposes of determining the presence of a quorum but will not be considered as votes cast for or against the proposal and will therefore have no effect on the outcome of the vote.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
A VOTE "FOR" ADVISORY APPROVAL OF THE COMPANY'S EXECUTIVE COMPENSATION.

PROPOSAL 4
ADVISORY VOTE ON THE FREQUENCY
OF THE ADVISORY VOTE ON THE COMPANY'S EXECUTIVE COMPENSATION
OF ONE, TWO OR THREE YEARS

In accordance with Section 14A of the Exchange Act, stockholders are being asked to vote on whether the Company should conduct an advisory vote on executive compensation (commonly referred to as a "Say On Pay" proposal and which is the subject of Proposal 3 this year) every one, two or three years. This advisory stockholder vote is commonly known as "say-when-on-pay".

Section 14A of the Exchange Act requires that we conduct a stockholder advisory vote of this nature at least once every six years. This proposal provides our stockholders with the opportunity to cast an advisory vote indicating their preference on how often the Company should include a Say On Pay proposal in its proxy materials for future stockholder meetings. By voting on this proposal, stockholders may indicate their preference for the Company to conduct the Say On Pay vote every year, every two years or every three years or stockholders may abstain from voting.

Beginning with the Company's 2012 annual meeting of stockholders, the Company has historically held an advisory vote on executive compensation every three years, with the exception of 2017, when our Board of Directors determined to voluntarily conduct an advisory vote despite the fact that the last advisory vote was held in 2015. Our Board of Directors has determined to conduct an additional advisory vote this year as well, and believes that a frequency of "every year" for the advisory vote on executive compensation will best serve the Company and its stockholders for the following reasons:

This vote is advisory, and therefore not binding on our Compensation Committee or Board of Directors. Notwithstanding the Board of Directors' recommendation and the outcome of the stockholder vote on this Proposal 4, the Board of Directors may in the future decide to conduct advisory votes on a more or less frequent basis and may vary its practice based on factors such as discussions with stockholders and the adoption of material changes to compensation programs. The Company's decision as to how frequently it will conduct "Say On Pay" votes will be disclosed via Form 8-K as required by the Securities and Exchange Commission. The choice of frequency that receives the highest number of votes will be considered the advisory vote of the stockholders. Abstentions and broker non-votes will not count in determining which frequency choice received the largest number of votes, and will have no direct effect on the outcome of this proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR A FREQUENCY OF ONCE
"EVERY YEAR"
FOR THE ADVISORY VOTE ON THE COMPANY'S EXECUTIVE COMPENSATION.

The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.
