Last year was a massacre. A bloody massacre. << Q's slides show a slaughter of WCDMA >> Slideware is good. << Eric- If you had to pick today, which is the better technology, cdma2000 or WCDMA? >> Technology platform - not even close in my mind - UMTS (which increasingly is called WCDMA) because of its concentration on services, its focus on internetworking and interoperability with the GSM core, evolved or not evolved, voice and data roaming, - and where it currently stands in standards development looking forward to the all IP core. Now as for the air interface ... the blend of 1xRTT and 1xEV is very promising ... but we are back to the world of vaporware. Not even commenced standardization on the 1xEV portion for GSM/MAP so worse than vaporware. Right now, WCDMA (which itself is vaporware) looks better in spec than 1xRTT, and its a darned shame that GSMers have to go through GPRS for network reuse. At best it will indeed be "adequate" for mobile data. For 3G licensees, with wide chunks of contiguous bandwidth the 1.25 Mhz carrier story, just isn't selling. Didn't sell day one, isn't selling now. ... biggest attribute of 1xRTT is it's lower risk on the short term ... it is based on very solid proven technology. It is of course a no brainer for cdmaOne operators. << And btw, don't forget that 1x moves up to 307 from 144 next year. >> Not forgetting, but WCDMA will be at the ITU IMT-2000 384 kbps requisite in a mobile implementation (vehicular or pedestrian) as opposed to fixed or portable, and (theoretically ... we will have to wait and see) available for commercial general deployment in roughly equivalent time frame as 1xRTT at 307 kbps, in those countries that have spectrum in 2GHz (which leaves us "Americans" out). Give me a Nokia Symbian Communicator with a 1xRTT or 1XTREME chipset for mobile use, and I'll be a very happy camper ... even happier if I can have a Verizon issued R-UIM that I can use interchangeably in a 1xEV PCMCIA wireless modem card or a GSM/GPRS Nokia Communicator. Multi-mode do every band and mode ... I don't want to wait that long. - Eric -
