Scheduled to die soon, if it hasn't already. I was a second-tier CDPD sub, via Earthlink, until about a year ago; they took a hit to move me to 1xRTT,
AT&T doesn't use CDMA... so they wouldn't be running 1xRTT. EDGE, perhaps?
Yes. AT&T also announced plans to get into the next layer, UMTS, which uses the concept of code division multiple access (CDMA), but isn't the same as Quallcomm CDMA (IS-95/IS-2000/CDMA2000). I don't know offhand which of the GSM-core technologies are/will be deployed by them at this time, as they aren't the carrier I currently use. (To my knowledge, however, AT&T does offer GPRS, which is slow, but if using at least two timeslots, still faster than IS-95 CDMA non-1X data. 8-) -- -- Todd Vierling <tv@duh.org> <tv@pobox.com> <todd@vierling.name>
