"It is planned to be exactly like the GSM overlay that CDMAOne did last year. Use the current GSM switches, network planning, but use the CDMA over the air waveform. this would mean replacing the basestations, but not the rest of the system.
In this respect, Qualcomm would also have the lead in that they have already proven this with IS-95 and the upgrade to CDMA2000 would then be just a simple set of chips in the basestation cards. Not like WCDMA, where they have an asynchronous pilot and have to figure out alot of system things like how it performs under load, how does soft handoffs really work wiht a collision detect, backoff, contention system, etc. This is largely untried and involves alot of coordination. It is yet to be seen how it works under load. Since they can't go commercial without invoking a trade restraint, then they cannot test this under fully loaded conditions (i.e. 1000's of customers during rush hour on a busy day...)."

One of the things I find the most disturbing about this whole discussion is that more we get into it the less sense it seems to make. Why would Vodafone, for example, go along with all this nonsense?

Engineer, Ericy say they invented soft handoff in 1988, or maybe 1938, well before Q! so they will have completed:

"...asynchronous pilot and have to figure out alot of system things like how it performs under load, how does soft handoffs really work with a collision detect, backoff, contention system, etc. This is largely untried and involves alot of coordination"

Maybe untried by Q! but Ericy has been focused on this since 1988! Or even sooner. You think being the market leaders they can't get those details sorted out in 10 years? They are now fine tuning the chip rate. They don't need to since they don't need any Q! technology, but they trying to bring Q! in for the benefit of humanity. They will cancel all IPR charges on GSM and everything for new year in accordance with their 'for the greater good and no company should stand in the way of the industry and the whole world'.
