Now this is what I call wireless! Yes folks, the Sierra Wireless AirCard 580 looks like it could provide a solution through a proprietary mobile broadband solution that is available to those who are wishing to drop the change on such an item. Speaking for myself, not sure if it is worth the extra monthly charge.

The Sierra Wireless AirCard 580 ($269.99 list; $79.99/month for service) delivers a high-speed wireless Internet connection on Verizon’s BroadbandAccess network (which is based on EV-DO) in 32 metro areas, using sleek, elegant software. It’s our current best choice for mobile computing, though you’ll need to have a Verizon business account and $80 per month to enjoy it.

EV-DO (Evolution Data Only) is the most compelling cellular technology we’ve seen in ages. This network is fast—way fast. In tests in New York City, northern Virginia, and Las Vegas, we got a solid average speed of 700 Kbps, with highs up to 1.2 Mbps. That’s more than double the speed of Cingular’s competing UMTS (Universal Mobile Telephone Service) network—which is in only six cities—and it’s four times the speed of Cingular’s nationwide EDGE network. Moreover, EV-DO just feels fast. Latency tests reflected the network’s speed: three times better than EDGE, but still three times slower than our in-house wired network.
