Sierra Wireless has just announced two new ExpressCard modems for HSUPA wireless users. Sporting download speeds up tp 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 are backward compatible with UMTS, EDGE and GSM networks world 'round, and they're being touted as "durable," meaning there are no little antennas or plastic pieces to break on you. That last part should be good news to all of you post-apocalyptic Road Warriors out there (or not -- they're still just regular ExpressCards, as far as we can tell). The AirCard 501 is slated for release later this month, while those of you interested in the AirCard 502 will have to wait until the first part of 2009.
