That is not totally true. If it was then noone would ever upgrade their infrastructure. Why is everyone moving to Fiber Optics in the telephone industry? Because it can carry MANY more conversations than copper, at a higher quality. TDMA and CDMA may both work with TCP/IP and PPP but CDMA is more efficient because it has the same packetized approach as both TCP/IP and PPP.

You cannot limit your thinking as to what the data prefers, the equasion is much deeper than that. If everyone used wet strings and cups instead of fiber/copper or whatever thay use then having a company like ATT, MCI, Sprint would be impossible. I understand that I am over reacting to your excellent description (thank you by the way), BUT, those of a technical bent on this board have a small obligation to help those of a non technical bent. If we do not include all of the facts then it is a disservice. What I mean is that it doesn't matter that both TDMA and CDMA work, they odviously do. The deeper and more important question (that I believe the pup was looking at) was which is cheaper and possibly better in the long run for operators to use? I think the answer is CDMA.

Please do NOT take me wrong your explanation helped and was excellent, it is always nice to see someone with a talent for teaching.
