On the other hand, Mike, we may very well see a 2.5 Generation asymmetrical WOFDM - EDGE product emerge as a predecessor to 3G xCDMA. Question is ... Will this supplement, or supplant the 3G xCDMA products; or just delay them ?? Please note that , in the following excerpt WOFDM is considered to be a GENERIC PRODUCT, NOT Wi-Lan's version (ie W-OFDM).. Ref... "In parallel with the expanding availability of high-speed transmission capabilities, increasingly demanding Internet applications and user expectations have emerged. Combining Enhanced Data-rates for GSM Evolution (EDGE) with Wideband Orthogonal Frequency Division Multiplexing (WOFDM) in an asymmetrical solution to address the challenges of high-speed data rates combined with wide-area coverage and good quality for wireless packet data services will be discussed in this talk. WOFDM can potentially support peak data rates on digital cellular downlinks up to several megabits/sec. EDGE is more attractive for uplinks to support several hundred kilobits/sec. Network based dynamic packet assignment can provide very high spectrum efficiency, and WOFDM supports good radio performance with inherent frequency diversity and support for interference suppression techniques.
