Data Rates Hola jack My example used GPRS to illustrate the capacity issue. In a CDMA system, adding new subscribers raises the noise floor, which will reduce the data rate. 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, In a CDMA system, there are no timeslots. The rate offered will also depend on the other voice subscribers in that cell, unless the cell is dedicated to data. Does burstiness of transmission play heavily here? Errors in the transmission are bursty. Is that what you meant? Errors will drop the rate seen by your application as they are corrected. Trying to get some feel for capacity constraints QCOm thinks that the average throughput on a loaded sector is an estimated 600 kbps on the forward link and 220 kbps on the reverse link, although I think this is exagerated. The network operators will decide the average throughput. Aside.... HDR, like cable modems, supports dormant IP addresses. This means that the portable device using HDR will need firewall software to stop spammers gathering information on 'live' IP addresses. Anyone care to comment? w.
