Las Vegas, USA-April 05, 2006

Sierra Wireless (NASDAQ: SWIR - TSX: SW) is working with wireless industry leaders to demonstrate next generation EV-DO Revision A wireless technology at CTIA Wireless 2006, which starts today and continues until Friday, April 7 at the Las Vegas Convention Center.

“In the wireless industry, the customer experience is shaped by the way the device, the network, and the service provider work together,” said Trent Punnett, Senior Vice President, Marketing and Corporate Development for Sierra Wireless. “Collaboration in early stage interoperability testing is incredibly important to the quality of our products, and these demonstrations are a natural result of those collaborative efforts.”

Sierra Wireless is collaborating with Nortel, Sprint, and Panasonic Computer Solutions Company to demonstrate the capabilities and benefits of EV-DO Revision A networks. With the increased downlink and uplink data speeds that Revision A provides in comparison with current EV-DO (Release 0) networks, faster file transfers and new applications will be available for mobile users, including video chat, VOIP, and sending large graphic or multimedia files over a wireless connection. The demonstrations will be hosted by Sprint in booth #1439 and by Nortel in booth #1835.

In these demonstrations, the company is previewing two new products designed for EV-DO Revision A networks. The AirCard® 595 wireless wide area network card is the newest addition to the award-winning Sierra Wireless AirCard product line. The MC5725 Mini Card embedded module is the fourth product in the company’s PCI Express Mini Card product line for AirCard Enabled™ mobile computing. Sierra Wireless and Panasonic Computer Solutions have integrated the MC5725 embedded module into Panasonic® Toughbook® notebook computers specifically for the demonstrations.
