EDGE As An Evolution Path to 3G
EDGE was first proposed to ETSI
Feasibility study was completed in 1997 and approved by ETSI
EDGE satisfies the 384 kbps data rate requirement.
It is a radio interface improvement but can be thought of as a system
concept that allows both GSM and GPRS to offer new services (i.e.
higher data rates and multimedia)
EDGE Architectures
EGPRS=Enhanced GPRS
BTS=Base Station
MS=Mobile station
GGSN= Gateway GPRS support node
SGSN= Serving GPRS support node
PCU=Packet control unit
TRU=Transceiver unit
EDGE does not bring about any direct architecture impacts (GSM 03.60)
