Sam, although you'll find a bazillion posts on the QCOM thread NOT related to your specific inquiry, it really is a gold mine of information on all things CDMA, TDMA, AMPS, and GSM including of course market shares of each. There is a CDMA organization, with a web site on the order of "cda.org" [not exact, but again you'll find it on the "Qualcomm - -Coming In To Buying Range" thread] which, notwithstanding its CDMA booster prejudice, is another terrific source of info.
The general answer to your question is that GSM/TDMA still rules the roost, but that the fastest growing segment, by far, is CDMA. With the Ericsson settlement with QCOM, it is now a foregone conclusion that TDMA/GSM is a legacy standard on its way out. AT&T will milk its huge investment in TDMA infrastructure for some time to come, but see Mossberg's column in today's WSJ: T's Digital One Rate program has already swamped their capacity. Particularly interesting in that Mossberg complains bitterly about daily dropped calls in Washington DC with his T service, whereas my Qualcomm phone has never dropped ONE call in my last five trips there. Ain't no cowinkydink. Regards, Mike Doyle |
