why are there so many dang technologys

evdo

That list is a little misleading. EV-DO and CDMA go hand-in-hand, since EV-DO rides on the CDMA network, and can't exist without it. TDMA is on the way out, and none of the big 5 cellular companies are using it primarily any more. OFDM doesn't really fit in that list at all, because it's not dependent a cellular phone network, and is completely separate. So really, your list should have two items:

CDMA + 1xRTT/EV-DO
GSM + GPRS/EDGE/UMTS

Those are the major competing cellular technologies right now. OFDM is purely a data technology, not related to cellular phones in any way, aside from it being offered initially by a cellular provider.]]> http://www.dslreports.com/forum/remark,12562136 Wed, 02 Feb 2005 15:59:42 EDT yeah http://www.dslreports.com/forum/remark,12561570 Dude : this reminds me of the dvd divx thing
