Abstract This paper is intended for Global System for Mobile C ommunications (GSM) operators interested in understanding the role of Enhanced Data rate for Global Evolution (EDGE) in the evolution toward Wideband C ode Division Multiple Access (WC DMA). EDGE can be introduced in two ways: (1) as a packet-switched enhancement for general packet radio service (GPRS), known as enhanced GPRS or EGPRS, and (2) as a circuit-switched data enhancement called enhanced circuit-switched data (EC SD). This paper, however, will only discuss the packet-switched enhancement, EGPRS. This paper describes EDGE technology and how it leverages existing GSM systems and complements WC DMA for further growth.
