Enhanced Data GSM Environment: A wireless digital celular technology. Specifically a 2.5G GSM upgrade, designed to provide data rates up to 384 Kbits per second.

EDGE, developed initially by Ericsson and scheduled for commercial use this year, uses 3G transmission technology but works in GSM’s (2.5G) frequency range. In addition EDGE works with new modulation and radio techniques that use existing frequency more efficiently.
