EDGE

Enhanced Data rates for GSM Evolution
A digital mobile phone technology which acts as a bolt-on enhancement to 2G and 2.5G General Packet Radio Service (GPRS) networks. That's why EDGE is sometimes refered to as 2.75G. This technology works in TDMA and GSM networks. EDGE (also known as EGPRS) is a superset to GPRS and can function on any network with GPRS deployed on it, provided the carrier implements the necessary upgrades.

EDGE provides Enhanced GPRS (EGPRS), which can be used for any packet switched applications such as an Internet connection. High-speed data applications such as video services and other multimedia benefit from EGPRS' increased data capacity. EDGE can carry data speeds up to 236.8 kbit/s for 4 time slots (theoretical maximum is 473.6 kbit/s for 8 time slots) in packet mode and will therefore meet the International Telecommunications Union's requirement for a 3G network, and has been accepted by the ITU as part of the IMT-2000 family of 3G standards.
