thanks pix
ya , u r very correct that , it is a very subjective discussion.
The QOS indicators are the RTT , Retransmissions , throughput/TBF .
Pix, my RTT value is around 280ms for EDGE and 450 ms for GPRS( pinging at firewall ).
average throughput/TBF DL/UL as 120kbps/25kbps EDGE
average throughput/TBF DL/UL as 36kbps/6.1kbps GPRS
i want to increase it further but how ??
can u suggest me what can i do furhter at radio level?
