Abstract
This paper is intended for Global System for Mobile Communications (GSM) operators interested in understanding the role of Enhanced Data rate for Global Evolution (EDGE) in the evolution toward Wideband Code Division Multiple Access (WCDMA). 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 (ECSD). 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 WCDMA for further growth.
