Good Post For Yahoo> why did T chose TDMA by: acurious1td 15618 of 15618 Remember back a few years.... T aquired McCaw's holdings. McCaw was smart enough to bail out of the investment in TDMA when CMDA first started. They realized that it was going to be a dog. Then T had so much equity in TDMA that they decided they could make this investment last. And NO! TDMA can NOT be just changed to CDMA. They would have to tear down the IS 136 stuff, although could keep all the IS 41 items. By keeping the IS 41 backbone they could run a dual mode or dual band CDMA system. The backhaul could be reused, and te towers could be reused. Although... Most of the tower sites would most likely be redundant, due to the propagation of the IS 95 air interface. Just my opinion, as I do not know the details of T's system. :-) It should happen, if T were smart. Although, it is unlikely that they would choose IS95 over Wideband CDMA (CDMA2000)
