Vancouver, B.C.-May 29, 2007

Sierra Wireless (NASDAQ: SWIR - TSX: SW) today announced that the AirLink PinPoint X and Raven X have been certified and are commercially available for use on the Verizon Wireless Evolution-Data Optimized, Revision A (EV-DO Rev. A) network. These robust, wireless devices support the latest in high speed data and are backward compatible to existing EV-DO Rev. 0 and 1x networks. 

The first two installments of the AirLink X Platform, the Raven X and PinPoint X, increase system processing power and expand the memory within an enhanced and scalable architecture optimized for current and future 3G wireless networks. AirLink X Platform wireless modems are always on, always aware, and are powered by ALEOS™ technology, the longstanding industry benchmark for reliable and feature-rich embedded intelligence. ALEOS enables persistent network connectivity, as well as remote device management, using best-in-class tools and utilities.

“The certification of the AirLink X Platform products is an important addition to our portfolio of supported data solutions,” said Cindy Patterson, vice president of enterprise data sales for Verizon Wireless. “This new offering is the latest example of Verizon Wireless’ industry leadership and dedication to providing our customers with cutting edge enhancements for enterprise applications.”

AirLink X Platform customers will benefit from download speeds averaging 600 to 1.4 Mbps and upload speeds averaging 500 to 800 kbps. Verizon Wireless’ Rev A network currently reaches 135 million people in 156 major metropolitan areas.

The Raven X is a robust communications and networking device designed to deliver reliable connectivity for broadband wireless data and mission critical applications. To expand its functionality and simplify deployments, the Raven X is equipped with both Ethernet and serial interfaces. The combination of an enhanced, robust processor, high-speed Ethernet and data session persistence provided by ALEOS make the Raven X perfectly suited for commercial wireless networking, e-commerce and business continuity applications. Intrinsic safety for use in hazardous environments and compatibility with numerous machine communications protocols make the Raven X equally suited for a long list of remote industrial solutions, including utilities, automation and infrastructure.

The PinPoint X is a compact, intelligent and fully-featured mobile communications platform with multiple peripheral connections, including serial, Ethernet and USB. Expanded I/O functionality in a separate connector includes four digital inputs, four analog inputs and two relay outputs unleashing extensive remote instrumentation possibilities. The PinPoint X is compliant with environmental military standards for vibration, shock, drop, high and low temperature and humidity. Its high-precision 16-channel GPS receiver, coupled with the rich embedded intelligence provided by ALEOS technology, makes PinPoint X the perfect choice for a broad set of mobile enterprise, public safety, fleet management and AVL solutions. 

“We are very excited about launching the X Platform products on Verizon’s EV-DO Rev. A network,” said Andy Berman, senior vice president and general manager, Mobile and M2M products for Sierra Wireless. “It will enable us to enhance existing solutions and introduce new customers to the powerful applications made possible by these highly intelligent devices coupled with the latest in wireless broadband technology.”
