Does anybody know how gsm equipment makers migrating to EDGE or 3G? I’m working on Nokia and know that in nokia’s implementation you only have to replace ordinary TRX to “EDGE TRX” to have EDGE implemented on GSM network. But how other companies like ericsson, siemens, motorola? Which network elements you have to replace to have EDGE working in you network?
I think it should be so easy in every equipment, so I wonder why so small amount of networks supports EDGE and so small amount of mobile phones support EDGE? I guess users should like to use EDGE because of the speed of internet connection which at EDGE around 100 Kbit/s
