Comets.com has been wired since 1995. In early 1999, we joined the AT&T Wireless Developer program, acquiring a series of CDPD wireless modems for testing. We are conducting research in the effective combination of wireless internet access and GPS geo-position information. We have currently left the AT&T Wireless Developer program in favor of Verizon's Wireless program. We are looking forward to the next generation of wireless (3G) connectivity, which will take a while before it's ready for prime time...

Many other devices use RF to establish connectivity, including wireless home networks (802.11a or b) cordless phones, and X10 wireless devices.
