Sierra Wireless has recently introduced the AirCard 501 and the AirCard 502 ExpressCard modems for HSPA mobile broadband networks, offering download speeds of up to 7.2 Mbps and upload speeds of up to 5.76 Mbps. Both modems sport a durable internal antenna design that includes no moving parts and extends a mere three centimeters (1 1/8 inches) from the ExpressCard slot. In addition, both devices offer backward compatibility with UMTS, EDGE and GSM networks; and both come with the Sierra Wireless TRU-Install software installation utility that makes installation a snap.
As for the differences, the first of the two modems supports 850, 1900, and 2100 MHz HSPA frequency bands — while the other one sings along 900, 1900, and 2100 MHz frequencies.
Commercial shipments of the AirCard 501 ExpressCard are scheduled for later this month, while the AirCard 502 ExpressCard will start selling during Q1 2009… More information about new HSPA cards is available on Sierra Wireless’ website.

Dusan has been using smartphones since their introduction and is now following the latest trends in the industry. The "convergence" is what he's most excited about, and writing about it is the next logical thing to do. He thinks that using a smartphone is what everyone who cares about their time should do. In addition to his interests in mobile phones, Dusan also loves to experiment with the latest web and mobile 2.0 services. The idea of accessing and managing your information from any device no matter where you are simply amazes him. Whether it's an online to-do list, note taking service or a video sharing social network, he's there to try it out. He admits though, he's still searching for the ultimate web-based organizational tool, which "sings" perfectly with the mobile PIM application. Dusan used to run SymbianWatch.com which later became part of IntoMobile. He lives in Serbia, South-East Europe, from where he edits the site on a daily basis.
