Did he say that the clear path to 3G was not CDMA, or just the current upgrade? I think the point here is that LU, and Nortel are not the leaders in EDGE. If T wanted to go with EDGE why would they switch vendors to LU and NT who are much more versed in CDMA. If I am correct EDGE is 2.5 G anyway. I think the quote saying "clear path to 3G" is what is in question.

"The question is, could T upgrade their system to 3G without using cdma?" Caxton, Remember that plans call for there to be a 3G TDMA standard in addition to the converged 3G CDMA standard in the IMT-2000 "family of standards" scheme. Could this 3G TDMA be what AT&T is aiming at? ==John C.

Caxton: T had signed letters of intent with Nortel and LU to upgrade their TDMA network with the latest technology. I called the author of the story and he said that it would not be an upgrade to CDMA. Just back from a week away so don't know what subsequent posts might offer. I recall a post on the Buy Range thread several months ago (April/May?) that indicated that T would likely upgrade its infrastructure with LU. An obvious choice for one reason, the old LU/T unity. But the second reason, and the interesting one, was that the poster (may have been engineer, w.molloy, walt, clark) indicated that LU's base station ASICS and other system upgrades for T's TDMA system were better adapted to eventual configuration and upgrade path to CDMA 3G than infra sold by other vendors. Don't know if this still holds true. In any event, no one ever said rooting out the installed legacy base of GSM/TDMA was going to be easy. Best regards. Steven
