EDGE is a technology that gives GSM the capacity to handle services for the third generation of mobile telephony. Using EDGE, operators can handle three-times more subscribers than GPRS, by either tripling their data rate per subscriber, or adding extra capacity to their voice communications. EDGE uses the same TDMA (Time Division Multiple Access) frame structure, logic channel and 200kHz carrier bandwidth as today's GSM networks, which allows existing cell plans to remain intact.
