That is more or less what AWS and Cingular decided about Dr. J and his band of merry hypesters when they chose the GSM migration path over CDMA since they think that cdmaOne in the real world is 3 to 3.5x GSM, and that is part of what Srategis was chartered by AWS to determine and Cingular of course absorbed ands operated several cdmaOne properties along the M&A trail so are in somewhat in a position to determine the real world credibility of such a statement. So I suppose that is also why the Cingular R&D department was dragged kicking and screaming to this ridiculous upgrade path?

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.
