EDAP or GPRS speed

Here ur question ask something diff while ur intension of asking question is diff. actually u want to ask what is the bit rate of GPRS between MS and BTS means wht exactly we get the speed out of mobile when we use internet connection.
.
.
For EDAP speed the timeslot we r assigning is the actual speed like, we are using 3 timeframe so it’s ABIS speed will be 192Kbps, so this is the ABIS speed not the Um speed, Um speed is maximum of 230Kbps but the EDAP is only 192Kbps n is divided into the all users using GPRS connection at a time, so in average i get 10-20Kbps in practical at my Nokia 3110c Modem so u can also calculate this. one thing to remember that not go to the Modem speed which shows u the 460Kbps or 115 Kbps whatever.

One thing to be noted that EDAP in ABIS allocation consumes 1 time frame of minimum n hence u can calculate the speed out of it.

we all know 1 timeframe’s speed is 64Kbps (that is 4 time slots)

n hence wht we use, if it is 2 time frame then EDAP’s speed will be 64*2=128Kbps
and similarily this goes on.

perfect ans for Speed of EDAP
If someone ask in interview the same question, the proper answer is.

It is the multiple of 64Kbps..
