Molloy,

Re: 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 understand from the Q's description of HDR that it is expected to operate up to 7 Mbps per cell with a 2.4 Mbps peak to an individual subscriber. Simplistic uninformed question from a non-techie: Does this mean that data transfer rate per subscriber starts to decrease after the first three (3X2.4=7.2) subscribers in a time slot, and then does so proportionately as more are added OR is it, as I suspect, more complicated than that? Does burstiness of transmission play heavily here? Trying to get some feel for capacity constraints among the tech choices that will be out there.

Thanking you in advance,

jack
