Re: EDGE technology

>>>> rf power control and noise ...

I take it that better control of handset power, dynamic and smarter frequency allocation and channel reuse based on a handset's distance from the base station reduces overall noise, increases channel throughput and improves signal reception for all active subscribers. This makes the overall system less error prone and tuned for higher performance.

You mentioned before that power control is easier to do now than in the past due to the work folks have done with cdma. I was led to believe that power control was one of the key cdma components pioneered and patented by Qualcomm. How is the EDGE implementation of handset power control different from such in a cdma system? If this is an apples (time division) to oranges (code division) comparison due to differing applications of similar techniques, just stating such will more than suffice.

>>>> voice capacity

I take it that channel allocation to EDGE/GPRS/GSM is dynamic and therefore moving more data in a cleaner environment enables more time for allocation of GSM voice channels and less capacity degradation due to data transmission via GPRS only.

Is voice on an EDGE channel and smaller time slices part of the current standard or potential future upgrades? And, don't these move EDGE into the realm of cdma and Qualcomm's IPR?

>>>> OFDMA

I chose to stay out of the OFDMA discussions so not to get confused. Maybe, after I get EDGE under my belt, I'll take a look in that direction.

>>>>> 8 phase shifting

I'm sure that part of EDGE is a term paper in itself. I never would of thought that my math degree would have allowed me to explore so many adventures.

Thanx for all your great input. In the overall context of wireless industry knowledge, I am convince more and more, every day, that my actual knowledge base is truly miniscule. However, I do know a wee bit more than I did yesterday.
