(Enhanced Data rates for Global Evolution - or GSM Evolution) A 2.5G digital data service provided by GSM cellular carriers worldwide, including AT&T and T-Mobile in the U.S. Also called "Enhanced GPRS" (EGPRS), EDGE works on EDGE cellphones as well as laptops and portable devices that have EDGE modems. Superseding the GPRS data service, EDGE users have experienced downstream data rates up to 200 Kbps. See cellular generations, cellular vs. Wi-Fi, GSM, GPRS, TDMA and UWC-136.
