Need to be compatible with analog pioneering AMPS through AMPS-TDMA at 30kHz bandwidth, no digital control channel for SMS nor WAPping. Never heard of EGPRS, I take it? Nor CDMA apparently but that's another matter. EGPRS let's a mobile use teeny-tiny 30khz channels for voice and nice big, well, almost big, 200khz GSM-like channels for data. And it's actually being built. And, yes, TDMA does support digital control channels. On other matters, I did hear a story about Sprint and CDMA. Sprint originally wanted GSM, but there no GSM-1900 systems back then, Europe being 1800MHz. So Sprint took the second, less preferable, choice of CDMA. Just a fun story I heard.

Ilmarinen, << Mötörölä is fun way of spelling Motorola >> It is kinda fun, I admit. << When USA ensured no GSM operators for some time to come >> That is not the USA way. The first all digital (PCS-1900) carrier to launch in the USA was APC Sprint Spectrum. The technology was GSM (Phase 2) and SMS (actually ESMS) was used for OTA launch day in November 1995. The reason that APC Sprint Spectrum was first to market in the USA is because thet were granted a "pioneer preference" license (one of 3 granted by the FCC) for GSM technology (in their case), so were able to build out earlier in the DC- Baltimore market than other carriers. By contrast, CDMA pioneer, USA based, Qualcomm was denied a "pioneer preference license by the FCC. As for spectrum auctions, which the USA "pioneered", GSM had an equal shot with IS-136 TDMA, and CDMA. << Need to be compatible with analog pioneering AMPS through AMPS-TDMA at 30kHz bandwidth, no digital control channel for SMS nor WAPping. >> Well, unlike Europe, WAP phones have been in plentiful supply, here for the better part of a year. CDMA of course, and 50% greater data throughput than GSM (500% faster throughput if you are talking Korea or Japan). I'm enjoying voice and data services on my 2nd WAP enabled CDMA phone. Two way SMS for OTA provisioning (and other applications) will be employed by Verizon before Christmas, nationwide. << Looking deeper into my old soul I must admit I see remenicences of the Mötötörölä-Nokia hinged mouse trap and diode case of late 80s, leading to the banana model of the present 7110 WAP, click, connecting people >> You turn a good and colorful phrase. Happy WAPping to you. I hate WAP! which is technology agnostic and which was "pioneered" by Unwired Planet, now phone.com, here in the good old USA. - Eric -
