EDGE (Enhanced Data rate for GSM Evolution) is a specification for data transfer on GSM networks.
EDGE features both a packet capability, EGPRS (Enhanced General Packet Radio Service), and a circuit switched capability, ESCD (Enhanced Circuit Switched Data).
EDGE packs up to 69.2Kbps into eight timeslots, for a total theoretical bandwidth of 473.6Kb.
GERAN (GSM/EDGE Radio Access Network) is the name given to the 3GPP standards for GSM/EDGE radio access.
EDGE is an update to GPRS. In turn, EDGE will eventually be replaced by WCDMA (Wideband Code Division Multiple Access).
The Universal Wireless Communications Corporation has introduced a standard for EDGE over IS-136 TDMA networks. This standard has been named EDGE Compact.
EDGE Compact supports 384Kbits over the more limited bandwidth provided by TDMA networks.
