Orlando, Florida-March 27, 2007

Sierra Wireless (NASDAQ: SWIR - TSX: SW) will showcase a variety of wireless technology applications and new devices at CTIA Wireless 2007, held this week at the Orange County Convention Center in Orlando, Florida. In keeping with the show’s theme, “What is wireless to you?,” Sierra Wireless is collaborating with customers and industry partners to demonstrate new wireless technologies, new form factors, and new customer applications for the company’s embedded module product line that show a wide range of potential audiences and markets. Sierra Wireless is exhibiting at the show in booth #3141.

HSUPA
The recently introduced Sierra Wireless AirCard® 881 PC card for HSUPA (High-Speed Uplink Packet Access) networks will be featured in an HSUPA demonstration hosted by Ericsson (Booth #3545), which will be streamed to a display in the Sierra Wireless booth. The AirCard 881 offers significant speed advantages over its predecessor, with a maximum theoretical downlink speed of up to 7.2 Mbps (megabits per second) and uplink speed of up to 2 Mbps. It is expected to begin commercial shipments mid-year.

Sierra Wireless AirCard® Wireless Adapters
Having recently extended the company’s flagship AirCard product line beyond its traditional PC card form factor into new ExpressCard and USB modems, Sierra Wireless will demonstrate the full range of the expanded AirCard adapter product line at this show for the first time. The new AirCard 595U USB modem and the new AirCard 597E ExpressCard will be used in the Sierra Wireless booth to demonstrate the advantages of increased uplink speeds in sending large files over an EV-DO Rev A network. The AirCard 597E is also part of EV-DO Revision A demonstrations hosted by Alcatel-Lucent and Motorola. The AirCard 875U USB modem and the AirCard 875 PC card will be used to demonstrate potential applications made available by mobile broadband network speeds. For the first time, Sierra Wireless AirCard adapters will be demonstrated on notebooks operating Windows Vista and Macintosh operating systems.

Sierra Wireless embedded modules and OEMs
Sierra Wireless will showcase a selection of products manufactured by original equipment manufacturers (OEMs), with mobile broadband connectivity supplied by Sierra Wireless PCI Express Mini Card embedded modules. These devices cover a broad spectrum of applications, from notebook PCs to fixed wireless terminals and routers, to M2M, and reflect the company’s diverse portfolio of OEM customers.

Included in this display is a demonstration of the Ericsson W25 fixed wireless terminal with the integrated Sierra Wireless MC8775V embedded module. The Ericsson W25 provides an alternative to fixed-broadband services for small office, home office, or temporary office customers, providing high-speed data, voice, and fax services.

Offering a glimpse of what Sierra Wireless embedded modules can offer in the area of M2M, the Isochron VendCast® integrated vending management solution is featured in the Sierra Wireless hospitality suite. Isochron vending machines with embedded Sierra Wireless modules offer customers reliable, real-time, two-way communications with their machines, allowing them to monitor for inventory or service alerts, enabling them to accept cashless transactions, and allowing for interactive communications with consumers at the point of sale.
