Technology Selection ... Hello Raymond, << If it's not American it's not accepted in the US. That was the prime reason why most american companies selected IS-95 and not GSM. >> Incumbent American cellular carriers (in the U.S., the A carriers and the B Carriers) all opted for either ANSI-41 US TDMA (IS-54/IS-136) or IS-95 CDMA because GSM was not standardized (much less commercialized) for 850 MHz spectrum and multi-mode AMPS/TDMA, AMPS/CDMA handsets were available early on (GSM/AMPS not till end of '98). The most notable exception in the U.S. was Bell South who chose PCS-1900 (GSM-1900) for the 1900 MHz spectrum they won in the PCS auctions while overlaying IS-136 (and/or upgrading IS-54 TDMA to IS-136) on their AMPS 850 MHz spectrum. Western Wireless did the same thing and eventually spun off their VoiceStrem PCS (GSM) network. PCS PrimeCo owned by a consortium of A&B cellular carriers and non-incumbent Sprint PCS both considered GSM for their 1900 MHz spectrum and their CDMA decisions were primarily based on vendor financing from AT&T and Nortel, both of whom were early CDMA licensees, had invested heavily in the technology, and were anxious to have it succeed. In addition IS-95 offered greater spectral efficiency than either GSM or US TDMA. GSM in Latin America got off to a slow start because virtually all spectrum there was in 850 MHz and GSM offered no 850 MHz solution until this decade. There is still relatively little 1900 (or 1800 MHz) awarded there. To say that most American companies selected IS-95 over GSM because it was American, is something of a stretch. Best, - Eric -
