WFI Wins Network Integration Contract From Major Wireless Carrier

SAN DIEGO, Feb 15, 2006 /PRNewswire-FirstCall via COMTEX News Network/ — WFI (Nasdaq: WFII), a global leader in the design, deployment, and management of wireless communication networks, technology networks and security systems, announced today that it was selected by a major wireless carrier to provide network integration services to improve operational efficiencies as a result of merger and consolidation activities. Under the terms of the contract, WFI will provide large scale, multi discipline, network integration, modification, and expansion services. This work was initiated in 2005 and is scheduled to continue through 2006.

According to the terms of the agreement, WFI will provide project management, file audit, physical site assessment, leasing, zoning, deployment and installation and commissioning services for sites across two large geographical regions. Further terms of the award were not disclosed.

“This announcement is very strategic for WFI,” said Eric DeMarco, President and CEO of WFI. “Although we haven’t announced a total dollar value for this contract because the project is being completed as sites are made ‘conversion-ready,’ this project illustrates an area of our business where a significant amount of opportunity exists in response to carrier merger and acquisition activity. With the recent merger of several large carriers, there is a pressing need for the companies involved to analyze and reassess their network operations, in addition to the ongoing optimization services they require. WFI has real experience resolving complex network challenges involving the integration of mixed technology platforms and carrier sub-systems, making us ideally suited to be the network technology partner and systems integrator of choice as carriers enhance their networks region-by-region.”
