         WIRELESS FACILITIES SECURES $35 MILLION IN PRIVATE PLACEMENT OF
                                PREFERRED STOCK


San Diego, CA, October 11, 2001 -- Wireless Facilities, Inc. (WFI) (NASDAQ:
WFII) today announced that it has reached an agreement to sell $35 million of
its preferred stock in a private placement to investment funds managed by Oak
Investment Partners. Oak Investment Partners was also the Company's largest
source of pre-public venture capital. All of the shares of preferred stock will
be sold by WFI.

Pursuant to the agreement, upon the completion of certain closing conditions,
affiliates of Oak Investment Partners will purchase shares of Series A preferred
stock for a common stock equivalent price of $5.50 per share. The shares of
Series A preferred stock will not be registered under the Securities Act of 1933
and may not be offered or sold in the United States absent registration or an
applicable exemption from registration requirements. Holders of the Series A
preferred stock may convert those shares into shares of WFI's common stock at
any time. After 33 months, the Series A preferred stock will automatically
convert into shares of WFI's common stock once it trades above $11.00 per share
for 30 consecutive days. The purchasers of the Series A preferred stock have
agreed to a lockup with respect to the shares (and the underlying common stock);
the lockup will expire in stages beginning 18 months from the date the shares
are purchased.

The Series A preferred stock will have a liquidation preference and price
antidilution protection. The liquidation preference will provide that upon any
liquidation, sale or change of control of WFI, holders of the Series A preferred
stock will be entitled to receive the amount invested prior and in preference to
any distribution to holders of WFI's common stock. Subject to certain exceptions
and limitations, the price

                                     -more-



antidilution protection will provide that, during the 18-month period following
the purchase of the Series A preferred stock, if WFI sells more than $15 million
of its stock at a common stock equivalent price of less than $5.50 per share,
then the conversion price of the outstanding Series A preferred stock will be
adjusted to be equal to the price at which such shares of stock are sold.

Upon completion of the sale of the Series A preferred stock, Bandel Carano, a
managing partner of Oak Investment Partners, will join WFI's Board of Directors.
Mr. Carano previously served as a member of WFI's Board from August of 1998 to
June of 2001.
