GPRS RF measurement

Roberto

For gsm handset, power vs time, phase error, freq error, BER measurements, etc are required in the 3GPP RF spec to be tested. How about multislot GPRS handset? I have read through the part concerning GPRS in 11.10 and found that the spec is not very clear. All the GSM tests are also needed in GPRS, but how many slots do we need to test? What is the power level difference between 2 adjacent time slots? Which coding scheme do we use to test? etc...

GPRS supports multislots, The result should be the same with different time slots. [br]<p align=right><font color=red>+3 RD币</font></p>
