Hot on the heels of the AirCard 595U, Sierra Wireless is expanding its HSUPA offerings with a new duo of USB modems. The AirCard 880U and 881U both connect to your Windows or OS X-based computer via USB, sport the company's TRU design features, and offer up a "theoretical maximum [upload] speed of 2Mbps," while downlink speeds tout a "theoretical maximum of 7.2Mbps." Additionally, in areas where HSUPA networks aren't available, both modems are "fully compatible with HSDPA, UMTS, EDGE, GPRS, and GSM network technologies on all frequencies currently used worldwide." The 880U is said to be "optimized for Europe and Asia, while the AirCard 881U is optimized for North America," and both units are slated to ship out next month.
