EDGE (Enhanced Data Rates for GSM Evolution)

Introduction to the EDGE standard

The EDGE (Enhanced Data Rates for GSM Evolution.) standard is an evolution of the GSM standard that modifies the type of modulation. Like the GPRS standard, the EDGE standard is intended to be a transition to third generation mobile telephony (3G). The term 2.75G is also used to describe the EDGE standard.

EDGE uses a different modulation than the modulation used by GSM (EDGE uses 8-PSK modulation), which means that base stations and mobile terminals need to be modified to support it.

EDGE increases the data rate by a factor of 3 but with a smaller coverage area. In theory, EDGE supports throughput of up to 384 Kbit/s for fixed stations (pedestrians and slow vehicles) and up to 144 Kbit/s for mobile stations (fast vehicles).
