Sierra Wireless Announces Supply Agreement for AirCard® 860 3G wireless card for use on Cingular's HSDPA network

AirCard 860 to bring the latest in 3G wireless technology to mobile professionals in the United States
Vancouver, B.C.-October 24, 2005
Sierra Wireless (NASDAQ: SWIR - TSX: SW) today announced a supply agreement with Cingular to deliver the Sierra Wireless AirCard® 860 3G wireless wide area network (WAN) card for HSDPA networks to Cingular for use on the company's HSDPA network. Commercial shipments to Cingular are expected to commence during Q4, 2005.

Out of the box, the AirCard 860 is fully functional on HSDPA, UMTS, EDGE, and GPRS networks. The AirCard 860 utilizes the 850 and 1900 MHz UMTS frequency bands and offers average data rates of 400 to 700 kbps, with bursts over 1 Mbps on Cingular's HSDPA network*. The AirCard 860 also operates on Cingular's nationwide GSM/GPRS/EDGE network, which provides average data rates of 75 to 135 kbps. Ideal for frequent travelers, the AirCard 860 enables international roaming on all four EDGE and GPRS frequency bands (850, 900, 1800, and 1900 MHz) used worldwide. Cingular has data roaming agreements with carriers in more than 90 countries.

HSDPA is an upgrade to UMTS networks that offers users significantly faster download speeds than earlier UMTS networks. For end users, this translates to an experience similar to a wired broadband connection while using email, connecting to server-based corporate applications through a VPN, or accessing the Internet, including streaming audio and video files.

"We are pleased to build on our long standing relationship with Cingular to bring the latest 3G wireless technology to their customers," said Dan Schieler, Senior Vice President, Worldwide Sales for Sierra Wireless. "With the AirCard 860 and Cingular's new HSDPA network, mobile professionals will be able to work wirelessly as effectively as they do from the office or from home, with access to email and online applications at broadband speeds."

The AirCard 860 wireless WAN card is a Type II PC Card with a slim, unextended design, allowing users to conveniently store the unit inside the laptop. For more information about the Sierra Wireless AirCard 860 wireless network card for HSDPA networks please visit
