most Digital areas do not support EVDO( High Bandwitdh ) or CDMA2000( 1X network ). You are still limited to IS-95( regular digital ).
That's only partially true. Both Sprint and Verizon have rolled out their EVDO REV-A networks, but you're right, they cover mainly the major metropolitan areas and neither carrier has any plans to fully implement EVDO REV-A to their entire digital footprints. Cingular does have Edge fully deployed, but most folks do not consider Edge broadband speeds, but more like very fast dial-up.
Both Verizon and Sprint have their 1XRTT data networks deployed on their entire digital networks. You're looking at 50-70 kbps speeds, which isn't horrible for things like e-mail and the like.
The EVDO networks were designed and rolled out specifically to target mobile laptop users who would want to use connection cards to access the web or their corporate networks and enjoy broadband speeds. Handheld devices simply do not have the processor speed to take advantage of the EVDO network, and a lot of people do not understand that.
The next generaton of broadband data is EVDV (Evolution Data and Voice). EVDO requires a carrier to assign parts of their spectrum for EVDO use, meaning that spectrum cannot carry voice traffic. EVDV allows the entire spectrum to carry both voice and data.
Sprint also plans to launch WiMax by 2010 and what positions them very well is that, because of the Nextel merger, they now own 85% of the spectrum where WiMax works.
Anyhow Zandor, I'm sure that's more than you were bargining for, but like Jon2, I know a thing or two as well. I should, I built Sprint's network in OH, KY, IN and western PA!
