Enhanced Data rates for Global Evolution
Enhanced Data rates for Global Evolution, or EDGE is a mobile phone technology that enhances upon GPRS. Thoeretically, this allows data transfers three times faster than standard GPRS, but is not always the case. The maxinmum data tranfer rate is 236 kbps but most networks runing EDGE are only configured for a data transfer rate of 135 kbps. It can be used on GSM and TDMA networks including Cingular and T-Mobile. EDGE can be implemented with no modification to the core network, the base station subsytem only need a transceiver installed to support EDGE.
