as i know that we use GMSk for GPRS and 8-psk for EDGE,
so my question is that can we achive 4 times the datarate of GPRS by using 8-PSK.
can we play vedio broadcasting in G2.5 in GSm network



reply in detail.

EDGE vs GPRS

I know by using EDGE for GPRS , the ability of this usage increase by the way for some reason also Video Broadcasting we must travel to 3G mobile communication SYSTEM

Dear Virus King

By using the 8-PSK we can use triple the rate of GPRS,also we can't use vedio broadcasting in G2.5 in GSm network as at least we need to use EDGE for the high data rate needed in video broadcasting

Best Regards
 

Re: EDGE vs GPRS

I think you better define what kind of Video Broadcasting first, I meant the picture size/quality...

EDGE and GPRS is just a means for communication, it has no limitation how you use it, but the datarate...

So, if you want to do a small size Video Broadcasting, I think it is ok.. As I have done an experience using a GPRS to try to watch a RMVB format video on a Computer, Audio could be ok, however, Video is very very slow, about 10-20 sec per frame... And the image size is 320x240...
 

Re: EDGE vs GPRS

Hi
According to 3GPP TS 05.02 version 8.11.0 Release 1999 "ETSI TS 100 908 V8.11.0 (2003-06)"
clause 3.2.4

A PDTCH/F using GMSK modulation carries information at an instantaneous bit rate ranging from 0 to 22,8 kbit/s.
A PDTCH/F using 8PSK modulation carries information (including stealing symbols) at an instantaneous bit rate ranging from 0 to 69,6 kbit/s.
