EDGE, which stands for Enhanced Data rates for GSM Evolution, is a faster version of GSM. EDGE is a high-speed 3G technology that was built upon the GSM standard.
EDGE networks are designed to deliver multimedia applications such as streaming television, audio and video to mobile phones at speeds up to 384 Kbps. Such speeds still pale in comparison, though, to standard DSL and high-speed cable access today.
EDGE delivers a boost of more than three times the capacity and performance over GSM.
The EDGE standard was first launched in the United States in 2003 by Cingular, which is now AT&T, on top of the GSM standard. AT&T, T-Mobile and Rogers Wireless in Canada all use EDGE networks.
