2'5G; GPRS - More Achievable?

If 3G proves too expensive, some networks may decide to provide mobile data service using General Packet Radio Services (GPRS). GPRS is also called 2.5G, because its capability falls halfway between the present GSM and the ultimate UMTS.
Like UMTS, GPRS will be 'always on' (permanently connected) with no need to wait to log on to the Internet - but initially speeds will be slow (about the same as a 28kbit/s modem).
However, enhanced modulation technologies such as Enhanced Data Rates for GSM Evolution (EDGE) could increase network capacity and data rates up to 384kbit/s . That would allow operators without a 3G licence to offer similar data services - but much cheaper and more quickly.
