Well, Cingular DFW is NOT 1900 (now or ever) so it's definately showing
850 regardless of what that label says. In fact, if you back up to the
carrier list page it doesn't show 850 for Cingular AT ALL--even before
the ATTWS merge they had lots of 850. Yet this map is also clearly not
just their 1900 areas so....

Sorry. . .I had forgotten that you had to dig around a little to find
the maps. I don't think these maps include any tower sharing
agreements between various companies though. . still pretty cool to
see.

P.S.. I"m really sorry if these links do not work. I don't post in

Re: Cingular vs T-Mobile for data
As TabooLexicon shows in the links provided above, there are actually
two maps for Cingular. [He also adds T-Mobile's map]
There is the: Cingular Wireless GSM 1900 map.
And the: AT&T Wireless PCS LLC (Cingular Wireless) GSM 850/1900 map.
As description for the previous two maps indicate, AFAIK, there is no
map on this site that shows Cingular 850 coverage only.
I have to agree with JN on this one.

The smaller carriers are putting off the conversion of TDMA to something
else until the Cingular TDMA network is turned off. There isn't any real
upside for them to rush to convert, given that the cost will not be made
up by increased sales of data services. Also, they can avoid the expense
of what the GSM carriers have gone through, first launching 1G GPRS,
then, 2.5G Edge, then 3G UMTS/HSPDA.

But a LOT of their income comes from Cingular customers roaming on THEM.
The vast majority of Cingular customers will have GSM-only phones long
before Cingular actually turns off TDMA. A couple of small carriers that
I figured would go down to the wire have already finished their
conversion and no longer offer TDMA phones on their website.
