Vancouver, Canada: May 10, 2011 - Sierra Wireless (NASDAQ: SWIR) (TSX: SW) today announced that EDMI has selected the Sierra Wireless AirPrime™ SL6087 embedded wireless module to provide cellular connectivity for EDMI’s new plug-and-play modular pod-based system that is integrated into the Mk7B smart single-phase electronic revenue meter.

The Mk7B is targeted to serve the global, low cost and high volume smart residential meter market. It includes an integrated modular pod-based system that allows EDMI to provide a cost-effective wireless point-to-point connection, simplifying maintenance in the field and providing remote management, upgrades, and configuration over the air.

EDMI is using the AirPrime SL6087 module, winner of the GSM Association’s award for Best 2G Module in 2010, with a ruggedized Embedded SIM. The combined solution allows a compact design with complete integration of advanced metering infrastructure (AMI) functionality. It also offers an optional Zigbee RF interface to connect a remote display panel. EDMI smart meters with embedded wireless connectivity comply fully with internationally recognized standards, providing a reliable, flexible, and cost-effective solution to allow users to optimize their energy consumption.

In February 2011, Sierra Wireless and EDMI together won the GSMA Global Mobile Award for Best Mobile Innovation for Utilities at the Mobile World Congress in Barcelona.
