<P><FONT SIZE=2>provisions,
the Company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is,
therefore, unenforceable. The Company's amended and restated bylaws provides for indemnification of its directors, officers, employees and agents to the maximum extent permitted by the Delaware
General Corporation Law. The Company's amended and restated certificate of incorporation provides that the liability of its directors for monetary damages shall be eliminated to the fullest extent
under applicable law. The Company has entered into indemnification agreements with its officers and directors. The Company maintains directors and officers liability insurance. </FONT></P>

undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report
pursuant to Section&nbsp;13(a) or 15(d) of the Exchange Act that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be the initial </FONT><FONT SIZE=2><I>bona fide</I></FONT><FONT SIZE=2> offering thereof. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to
the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is,
therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of the expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. </FONT></P>

<P><FONT SIZE=2>Ladies
and Gentlemen: </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At
your request, we have examined the Registration Statement on Form&nbsp;S-8 of Wireless Facilities,&nbsp;Inc., a Delaware corporation (the "Company"), to be filed with
the Securities and Exchange Commission in connection with the registration under the Securities Act of 1933, as amended, of an aggregate of 1,000,000 shares of the Company's common stock, $0.001 par
value (the "Stock") issuable from time to time in connection with the Company's 1999 Equity Incentive Plan (the "Plan"). </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
the Company's counsel, we have examined the proceedings taken by the Company in connection with the adoption of the Plan and the authorization of the issuance of the Stock under the
Plan, and such documents as we have deemed necessary to render this opinion. For the purpose of the opinion rendered below, we have assumed that in connection with the issuance of Stock under the
Plan, the Company will receive consideration in an amount not less than the aggregate par value of the Stock covered by each such issuance. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based
upon and subject to the foregoing, it is our opinion that the Stock, when issued and outstanding pursuant to the terms of the Plan, will be validly issued, fully paid and
nonassessable. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
consent to the use of this opinion as an exhibit to the Registration Statement. </FONT></P>

Wireless Facilities,&nbsp;Inc., which report appears in the December&nbsp;31, 2004 annual report on Form&nbsp;10-K of Wireless Facilities,&nbsp;Inc., which is incorporated by
reference herein. We also consent to the use of our report dated April&nbsp;29, 2005, with respect to management's assessment of the effectiveness of internal control over financial reporting and
the effectiveness of internal control over financial reporting, which report appears in the Form&nbsp;10-K/A dated April&nbsp;29, 2005, incorporated by reference herein. Our report on
the consolidated financial statements and schedule refers to a change in method of accounting for goodwill. Our report dated April&nbsp;29, 2005, on management's assessment of the effectiveness of
internal control over financial reporting and the effectiveness of internal control over financial reporting expresses our opinion that Wireless Facilities,&nbsp;Inc. did not maintain effective
internal control over financial reporting as of December&nbsp;31, 2004 because of the effect of a material weakness on the achievement of the objectives of the control criteria, and contains an
explanatory paragraph that states that the material weakness in internal control over financial reporting related to the Company's procedures over period-ending closing journal entries related to
income taxes. </FONT></P>
