Sierra Wireless has just introd two new ExpressCard modems for HSUPA wireless users. They feature download speeds up to 7.2Mbps and upload speeds up to 5.76Mbps. The AirCard 501 supports 850 / 1900 / 2100 MHz bands, while the AirCard 502 covers 900 / 1900 / 2100 MHz.

Both bend over backwards, being backward compatible with UMTS, EDGE and GSM networks the world over and they’re being called durable, because there are no little plastic pieces to break on you and make you curse. The AirCard 501 is scheduled for release later this month, but if you’re interested in the AirCard 502 you’ll have to wait until early 2009.
