EDGE TECHNOLOGY

Abstract

EDGE is an enhancement to the GSM mobile cellular phone system. It is a step towards the evolution of 3G networks. The name EDGE stands for Enhanced Data rates for GSM Evolution. When applied to GSM/GPRS networks, EDGE dramatically increases data throughputs, as well as network capacity. EDGE provides three times the data capacity of GPRS. Using EDGE, operators can handle three times more subscribers than GPRS, triple their data rate per subscriber, or add extra capacity to their voice communications. EDGE uses the same TDMA (Time Division Multiple Access) frame structure, logic channel and 200 kHz carrier bandwidth as today's GSM networks, which allows existing cell plans to remain intact. But it uses a new modulation scheme, 8-PSK. In this seminar an overview of the EDGE technology, the modulation scheme and its applications will be discussed.
