Wireless Matrix Joins MultiSpeak Initiative

Market Wire, April, 2008

Wireless Matrix Corporation (TSX: WRX) today announced that it has joined the MultiSpeak® Initiative for software application integration and interoperability.

Created by the National Rural Electric Cooperative Association, MultiSpeak is a software specification designed to help electric cooperatives automate business processes and exchange data among software applications. The MultiSpeak specification helps vendors and utilities develop interfaces so that software products from different vendors can interoperate without requiring the development of extensive custom interfaces.

According to the NRECA's MultiSpeak website, "It is expected that MultiSpeak will make cost-effective, integrated software applications more readily available to utilities."

Under the initiative, Wireless Matrix's FleetOutlook suite of applications will be integrated for interoperability with other applications that adhere to the MultiSpeak specification. This integration will allow FleetOutlook to exchange data with a variety of applications already in use by fleets in the markets Wireless Matrix serves. As a result, FleetOutlook will support intuitive operation with other applications, and can be deployed more quickly to realize a faster return on investment.

"The addition of the MultiSpeak integration to FleetOutlook provides plug compatibility with other industry standard applications for use by rural utilities," said J. Richard Carlson, president and CEO of Wireless Matrix. "The reduced total cost of ownership and quicker time to deploy our solutions will allow customers to leverage greater value from their fleets faster, with reduced risk. Integrating with other leaders is a key part of our strategy."

Wireless Matrix is a member of the National Rural Electric Cooperative Association. The company has over 7,000 subscribers among approximately 25 utility companies, including Dominion Resources, Union Gas and Trinity Valley Electric Co-op.
