TELUS Mobility today introduced the Sierra Wireless AirCard(R) 580 wireless wide-area network card, the first in Canada capable of operating on high-speed EVDO networks. TELUS Mobility plans to introduce EVDO (for Evolution, Data Optimized) service in selected Canadian markets in the first quarter of 2006. EVDO is next-generation wireless network technology that offers data transfer speeds of approximately 400 kilobits per second, at least six times faster than current wireless data speeds.

The network card takes the data and cuts it up into packets of a certain length. It then packages the data with codes. These codes tell a receiving network card where the data packet starts and ends. The point behind the packaging is so that the network cards can read the data, and can tell if any of it was lost or damaged by noise.

Operating on TELUS Mobility's national 1X wireless voice and data network now, the AirCard 580 offers forward compatibility with EVDO through a simple software upgrade. The AirCard 580, a follow-up to the popular Sierra Wireless AirCard 555 offered by TELUS Mobility since 2000, fits a standard Type II PC Card slot on portable computing devices. It offers improved reception, thanks to its flip-up, vertically polarized antenna, and lower battery consumption.

Designed for connectivity to EV-DO Revision A networks, the AirCard 597E is capable of peak data speeds of 3.1 Mbps on the downlink and 1.8 Mbps on the uplink when operating on a Revision A network. For use in areas where EV-DO Revision A is not yet available, the card is compatible with widely available EV-DO Release 0 and CDMA 1X networks.

The X90Le model ... includes a built-in smart card reader with Citrix Password Manager pre-installed for convenient and effective two factor security. And because these Wyse mobile thin clients are designed for access to applications that are fully managed in the data center, they are inherently more secure from theft, viruses and other malicious software attacks.
