Edge
Enhanced Data rates for GSM Evolution ( EDGE ), Enhanced GPRS ( EGPRS ), or IMT Single Carrier ( IMT-SC ) is a backward-compatible digital mobile phone technology that allows improved data transmission rates, as an extension on top of standard GSM. EDGE can be considered a 3G radio technology and is part of ITU's 3G definition, but is most frequently referred to as 2.75G. EDGE was deployed on GSM networks beginning in 2003— initially by Cingular (now AT&T) in the United States.
EDGE is standardized by 3GPP as part of the GSM family, and it is an upgrade that provides a potential three-fold increase in capacity of GSM/GPRS networks. The specification achieves higher data-rates by switching to more sophisticated methods of coding, within existing GSM timeslots. Introducing 8PSK encoding, EDGE is capable of delivering higher bit-rates per radio channel in good conditions.
EDGE can be used for any packet switched application, such as an Internet connection. High-speed data applications such as video services and other multimedia benefit from EGPRS' increased data capacity. EDGE Circuit Switched is a possible future development.
Evolved EDGE was added in Release 7 of the 3GPP standard. This is a further extension on top of EDGE, providing reduced latency and potential speeds of 1Mbit/s by using even more complex coding functions than the 8PSK originally introduced with EDGE.
