Tom, regarding the WiMAX standard, can you or anyone comment on whether WiMAX requires much greater bandwidth in a given spectrum than CDMA2000 or WCDMA? My impression is that WiMAX, because of the way it uses spectrum, creates interference on wavebands already used for CDMA or GSM, or their variants. And OFDMA may make the spectrum more efficient but does not eliminate the interference problem. My sense (and I admit to a lack of understanding of the nitty gritty parts of WiMAX) is that WiMAX begins to falter if too many users attempt to use a single base station. In general, from what I've read, I still believe that WiMAX is NOT A SUBSTITUTE but a COMPLEMENT to CDMA2000 or WCDMA. Someone please correct me if I'm wrong. But if this is true, then sooner or later, as others have also commented, the operators of a WiMAX system effectively run out of spectrum or end up with a service that bogs down when traffic gets heavy.
