Hi Chaz - re GPRS

The latest report is that GPRS will actually run for the average user for average use
(i.e. just plain average) at about 30 kbps.

Is that close to accurate?


GPRS is slot based. Basic rate GPRS (1 Time Slot) is 9.6Kpbs.
The rates being tossed around in the press releases depnd on multislot GPRS. Multislot allocation rests with the network operators.

The (per cell) trade off faced by network operators is two fold
1. Number of data users vs Number of Voice users
2. The Number of Data Users vs the average data rate/user

Obviously, the network use models will be set up to maximise revenue.
Will maximum revenue result in 30Kbps data service? I don't know - but, IMO, I doubt it.

In other words is this because of sharing among users, so the more users per cell, the slower the speed?

Absolutely.

And what realistically follows GPRS?
Must that be EDGE?


EDGE is proposed as a successor to GPRS, but it doesn't have to.
EDGE is a brand new technology, utilising a different modulation method 'over the air'.
