WFI ANNOUNCES AGREEMENT TO SELL EMEA BUSINESS TO LCC INTERNATIONAL

Transaction Is Another Milestone In WFI’s Transformation Strategy

SAN DIEGO, CA — MARCH 9, 2007—WFI (NASDAQ: WFII), a leader in the design, deployment and management of wireless communication networks, information technology solutions and security systems, announced today that it has signed a definitive agreement with LCC International (NASDAQ: LCCI) to sell WFI’s entire Europe, Middle East and Africa (EMEA) business in a cash for stock transaction valued at $4 million. The transaction is subject to customary closing conditions and is expected to close in the first quarter of 2007.

This transaction allows WFI to focus on a number of domestic opportunities and business initiatives, such as:

· Allowing WFI to place greater focus on the growing domestic opportunities arising from the Advanced Wireless Services (AWS) spectrum auction in the United States

· Minimize risk by exiting business where WFI does not already have a substantive business with critical mass

· Further leverage WFI’s domestic operations to maximize efficiency

· Improve WFI’s free cash flow and liquidity

“The sale of WFI’s EMEA business is consistent with our strategy to focus our business even more directly on the growing domestic opportunities in our industry,” said Eric DeMarco, president and CEO of WFI. “LCC has an established critical mass in Europe that can more effectively support a profitable operation in this region. This business has made notable achievements, including significantly diversifying both its geographic reach and customer base, and I want to thank our employees for their dedication and efforts. Now, by divesting of this business, WFI can dedicate even more of its resources on pursuing the opportunities arising from the AWS Spectrum Auction, as well as other

profitable growth areas in the U.S. market. Additionally, this transaction will improve WFI’s free cash flow and overall liquidity as we pay down debt, another aspect of our transition strategy.”

WFI’s EMEA business operation is headquartered in Guilford, England, just outside of London, and includes additional regional offices located in France, Sweden, Turkey, Austria and Egypt.

In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long Lived Assets,” WFI’s EMEA operations will be treated as discontinued operations in WFI’s financial statements for the fourth quarter and full year ended December 31, 2006. In addition, all prior year presentations are required to be reclassified to reflect the discontinued operations. WFI does not currently expect the divestiture costs related to this discontinued operation to be material. The employees associated with WFI’s EMEA operations will become employees of LCC under the new ownership.
