Jim, sorry to take so long to get back to you, but the vacation was great, golf was good, surfing was great. I think that when we all get to UMT-2000 standards, it is the same. they all require at least 384k bps on a mobile channel and up to 2 MPS on a fixed channel. the WCDMA stuff is >5 Mhz due to lots of history..;^). the Qc stuff is still in 1.25 Mhz and gets to 1 Mbps, or 2 Mbps on a 2.5 Mhz channel (Dr. Jacobs at CICC in November...IS-95HDR). I still think this is twice the proposed spectral efficiency that WCDMA proposes without some big format change and NO backwards compatibility. So what was your point? the 1% for data phone calls that you cite is for analog cellular over lines which cost as much as $0.20 a minute. The analog cellular runs at best about 2400 baud but more like 300 baud with the drop out and fading, so the cost is very big. but if you take the cost of US PCS at $0.20 a minute and factor in that you can get 14.4k PACKET connections with a guaranteed bit error rate of less than 2%, which do not have 20-40 seconds of modem training time in at $0.20 a minute, or have retransmitt problems for data loss, then the actual improvemnt is more like 20-50 times from analog cellular to digital cellular with packet. Now sending a 1k byte file or email message is more like $0.07 cents or less rather than $1.20 cents or more today. I think that data will become more important as groups like Japan turn on CDMA in the next 6-12 months and the US rollout of CDMA data this year. I also think that IS-95C with the combined 8 channels for up to 76k bps data will come into play alot.
