TMH, << QCOM only has to retain control of the core >> They have essential IP on some elements of the core but (I don't think) they control the core. The core is Wideband CDMA operating asynchronously with 5 MHz carrier. They attempted to control the core (after the fact). Nobody let them. QCOM controls narrowband CDMA which they commercialized. Wideband CDMA (W-CDMA) is now being commercialized. AT&T controlled IS-136 TDMA (one of many implementations of TDMA, and one of the poorest). The GSM community controlled the GSM architecture (and standard) - another TDMA implementation and a much better and more enduring one than the D-AMPs and IS-136 implementations. - Eric -
