EDGE (Enhanced Data for Global Evolution)

EDGE is a data system used on top of GSM networks that provides faster data speeds than GPRS, the technology it makes obsolete. It has a theoretical maximum downlink data rate of nearly 475Kbps, which qualifies it as a 3G technology based on ITU guidelines, even if typical implementations are configured for non-3G speeds. Generally, it is referred to as 2.75G.
