High-speed data in EGPRS ― A physical layer challenge

摘要

More a question of "when" than "if," there is no doubt that EDGE is happening ― and North America's major operators are announcing their commitment to it. The enhanced general packet radio system (EGPRS) is a subset of the enhanced data rates for GSM evolution (EDGE). This is the standard for the European Telecommunication Standard Institute- (ETSI) and Third Generation Partnership Project- (3GPP) compliant standard for 2.5G protocol and 3G evolution path. The main benefit of EGPRS is its provision of a cost-effective way to ease into next-generation services and applications. It accomplishes this by enabling increased data transmission rates (through-put), improved quality of data services (reliability, response time) and increased spectral efficiency. It thereby enables a smooth evolution of current/existing global system for mobile communications (formerly Groupe Speciale Mobile) (GSM) and general packet radio service (GPRS) networks to next-generation applications at a relatively low upgrade cost.
