| PreviousGPRS (2.5G) | EDGE (Enhanced Data Rates for GSM Evolution) |
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).
