One more thing regarding the Arthur Anderson presentation of the economics of CDMA over GSM infrastructure. They showed a future capacity doubling of CDMA in the near future through some Qualcomm enhancements to the air interface. When I asked the Qualcomm people what this was all about, they clammed up and said they haven't released anything yet about this but would be in the future. The mentioned there is a capacity doubling and a 2 dB improvement in the link budget. Will be released as IS-95C in the future but that's all I could get out of them.

Also, the GSM bigots there have now decided that GSM capacity is equal to CDMA due to a reduction in reuse from 12 to 6 through frequency hopping and other GSM features. While I can testify that hopping does allow better reuse, as I've done it even more aggressively than every 6 cells I think you'll find that quality gets worse and it takes a hell of a lot of attention to the handoff parameters to make it work right. But, basically I agree with the GSM bigots that to assume GSM is an N=12 reuse is a fallacy now days since anyone with capacity problems is pushing it much harder than that now.

IS-95 had better find a way to get 2X capacity IMHO or it's not that much better than GSM in capacity and is still not equal in roaming or features.
