cdma2000 vs VW40 <With the Asynch pilot channel, I suspect that they will take a lot longer than a year to satisfy the carrier signoff reuirements for dropped calls during handoff. But that is just my opinion.> That seemingly innocent little comment deserves a bit closer scrutiny. Let's just put W-CDMA back on the vapourwear coathanger for a minute. If some company buys W-CDMA on the promise that it isn't vapourwear and it really will work, they won't be at all impressed if it takes a year [or more] to 'tune it up' so the calls don't drop and all that stuff which makes subscribers unhappy. Qualcomm, the experts, took a couple of extra years to 'tune up' cdmaOne so that it worked in practise. AirTouch in Los Angeles, Trenton, Korea, Hong Kong all had problems getting going. cdma2000 is likely to 'tune up' a LOT faster than W-CDMA which is starting from home base [to use some baseball jargon]. To score a touchdown, they will have to hit a hole in one on the first throw. Given the history of Ericy, Motorola and Nokia experience with CDMA, it is not so simple to do that. With much bigger bandwidth and a lot more data and more complex ASICs, I imagine that it will be very, very difficult for those new to CDMA to make it sing [or get a hole in one]. It doesn't seem likely that NTT, China Unicom or others will goof around for a couple of years while the mechanics tune up VW40, especially since it doesn't do anything that cdma2000 can't [other than have incompatible chip rates and fun stuff like that]. It seems that cdma2000 is off and running. Ake Persson seems to be not too shy about agreeing that they will be selling a LOT of cdmaOne gear and no doubt cdma2000 gear out of Lusk Boulevard HQ! If VW40 turns to reality in the form of W-CDMA with weird chip rate, weird Asynch pilot channel and weird Reed Solomon Concatenated Convoluted Coding I'll be very, very surprised. My bet is a tamed down W-CDMA indistinguishable from cdma2000 other than the paint job and the sound of the horn. Mqurice [Meanwhile, if, as JGoren says, the capital gains taxes go, that will be another enormous boost to the USA sucking in the world's capital and an acceleration in The New Paradigm. Also, I don't think Clinton and Barshefsky have figured out what to do about Free Trade in Sheep - APEC Trade Ministers are due here in a week or so, so the timing is fun. If you watch TV, you'll see me running around downtown near the APEC meeting in sheep's clothing, fangs bared]. PS: Just making up for lost time - I'll knock off now.
