Stationery v. mobile data rates - GSM v. CDMA

I've reviewed the thread and don't see an issue to 'stationary vs
mobile'. This view is incomplete.

Mobility does affect Data rates. For example, during rapid fade. However, the data rates will generally recover.

Much more important is the capacity of a given cell. All data services offer variable data rates, and not for the benefit of the subscriber.

A high data rate will be touted, because that's what will attract new subscribers, but the actual data rate offered will be much less, and will be dependent on the number of subscribers attempting to register in a given cell.

For example most initial GPRS services will actually be around 9600bps. Additional speed will be made available at the cost of additional timeslots.

(I'm not taking a dig a GPRS, ALL data services will operate this way).
