RESTON, VA - Wireless Matrix Corporation (TSX: WRX) announced today that the Company has successfully bid and entered into an Amended and Restated Asset Sale and Purchase Agreement dated July 20, 2006 to acquire substantially all the assets of Mountain View, CA based MobileAria, Inc. Wireless Matrix will pay cash consideration of $11,005,000 and assume certain liabilities to acquire the intellectual property and customer contracts of Mobile Aria. Consummation of the sale is subject to court approval and consent by parties in interest. If approved by the court, Wireless Matrix expects the sale to be consummated by the end of August 2006.

The acquisition provides three significant benefits to Wireless Matrix. MobileAria brings to the Company a proven applications platform that enables Wireless Matrix to meet the needs of Enterprise-level customers with today’s solutions as well as a highly capable applications team who are designing new applications leveraging wireless broadband networks. It also provides a strategic relationship with Verizon Communications, MobileAria’s primary customer, with over 10,000 subscribers today. MobileAria’s hardware technology accelerates the Company’s entry into the wireless broadband market with its EVDO CDMA hardware capabilities. MobileAria’s leading-edge high speed wireless broadband device, certified and proven on the Sprint and Verizon networks, provides the field workforces of enterprise users’ unfettered and secure access to all desktop and web applications.

“The acquisition of MobileAria is another major step along our transformational strategy,” said J. Richard Carlson, President and CEO of Wireless Matrix. “Not only does MobileAria fill out our hardware solution set, but this acquisition accelerates our entry into the hosted applications space, enabling Wireless Matrix to serve a much larger target market demanding new solutions that leverage wireless broadband networks.”
