Vancouver, British Columbia and Spokane, Washington -January 18, 2005

Sierra Wireless (NASDAQ: SWIR - TSX: SW) and Itronix Corporation today announced that Itronix has selected the Sierra Wireless EM5625 embedded module to provide its GoBook® series wireless rugged notebooks access to CDMA 1xEV-DO networks. The dual-band EM5625 embedded module will enable users to connect to email, the Internet, and information residing on corporate servers, including data-heavy applications like streaming video and large graphics files, using one of the fastest wireless wide area network technologies currently available. Itronix’ newest model, the recently introduced GoBook III 1.8 GHz wireless notebook, will feature this module.

“Based on our past experience with using earlier Sierra Wireless’ embedded modules in our GoBook series laptops, we are confident in our choice to migrate to the next-generation EM5625 embedded module,” said Matt Gerber, Senior Vice President, Product Line Management for Itronix. “Sierra Wireless offers the expertise and support we need to integrate the wireless functionality seamlessly into our products, letting us concentrate on getting to market as quickly as possible.”

“Original equipment manufacturers put a lot of trust in our embedded modules when they integrate them into their own products, and that is something we don’t take lightly,” said Dan Schieler, Senior Vice President of Sales, Americas and Worldwide OEM for Sierra Wireless. “The Sierra Wireless EM5625 embedded module offers OEMs the opportunity to integrate the newer, faster wireless access technology into their devices with the confidence that they are backed up by the reliability and support that come with Sierra Wireless products. We are pleased to work with Itronix to deliver EV-DO connectivity in the GoBook III notebook computer and the full series of GoBook notebooks.”

The dual-band Sierra Wireless EM5625 embedded module provides a powerful, reliable, wireless engine that can be easily integrated into a wide variety of mobile devices and offers “always-on” voice, data, and messaging functionality at typical data speeds of 300-500 kbps, with bursts up to 2.4 Mbps. Additional features of the EM5625 module include enhanced power management to optimize battery life, as well as gpsOne™ capability, which complies with E911 requirements for emergency location. Sierra Wireless also offers a comprehensive suite of integration services for original equipment manufacturers (OEMs), including a Universal Development Kit to simplify the integration process and accelerate time-to-market.

The GoBook III, featuring the Intel Pentium M 1.8 GHz processor, is one of the most powerful rugged wireless laptops available today. Featuring up to four integrated radios, which now will include the Sierra Wireless module, it also is the only wireless rugged laptop to feature fully integrated state-of-the-art GPS. In addition to its processing power, and its advanced integrated wireless options, the product also features a powerful ATI Radeon Mobility video engine, with 64 MB of dedicated RAM for truly exceptional performance in demanding graphics applications.
