With regard to capacity, it appears to the layman, that AWE's and Cingular's decision to use GSM instead of TDMA or CDMAS had nothing to do with capacity issues. TDMA and GSM have similar capacity claims, so why switch to GSM ? If CDMA1X adds an additional 1.5X spectrum efficiency to CDMAOne, one can surmise that 1x is 4.5-5.25x more efficient than GSM or TDMA. AWE went with GSM for handset selection and a perceived easier migration to WCDMA at the request of DoCoMo. The almost $10billion investment by DoCoMo I'm sure played in that decision making process. QCOM says that they are going to double efficiency of 1X with antenna technology in the future, lets see 2x5=10. Time will tell.
