Currently in India i think 2.5 G technology service provider uses. in that we are getting GPRS and EDGE services we can access internet but speed is not good max speed is 140 kbps or 150 kbps. How much speed we will get after launching 3G ? How 3G is different from existing services ?

2G and its further upgardation till 2.75G networks (existing) were built mainly for voice data and slow transmission. Due to rapid changes in user expectation, they do not meet today's wireless needs.

cellular services (2G) combined with GPRS became 2.5G and provide data rates from 56 kbit/s up to 114 kbit/s . It can be used for services such as Wireless Application Protocol (WAP) access, Short Message Service (SMS), Multimedia Messaging Service (MMS), and for Internet communication services such as email and World Wide Web access.

GPRS networks (2.5 G) evolved to EDGE networks (2.75 G) with the introduction of 8PSK encoding and referred as the 2.75G. It provide high data rates.
EDGE networks the introduction of UMTS networks and technology is called pure 3G. 3G Bandwidth 5 MHz
