GSM and high speed data?

Do carriers with GSM systems offer high speed
data services like VZW's Express Network (1xrt)?

Is GSM widely deployed, and available
on major interstates?

I'm just curious.

Thanks in advance.

GSM is widely deployed around the globe (See http://www.gsmworld.com) but
not so much in USA. It should cover major US interstate highways. You can
see the coverage by Cingular, ATTWS, and T-mobile. GPRS is around the speed
of a dial up.

Hasn't AT&T Wireless completed the overlay of their TDMA system with GSM,
so that anywhere they had TDMA service, they now also have GSM service?

Unluckily GSM doesn't get as much usable range as old TDMA, so there are
now "holes" they are slowly filling in.

Most TDMA customers are freaked out by how spotty the GSM network is by
comparison. Its only 'real' advantage to voice/sms users is higher
density in very urban areas. You're less likely to wait 30 seconds to
get a call out at a major event or rush hour traffic. Out in the sticks
you're much better off with old TDMA than GSM.

Hmmmm... that's right. GSM has a hard distance limit of 35km (21mi)
due to its time slot length, whereas "TDMA" (IS-136) has a much larger
distance limit. So just slapping GSM equipment on those towers in the
West is going to leave some huge holes.
