EDGE
(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.

Flatland by Abbott, Edwin View in context
There was no expression of either fear or surprise upon his tranquil face, yet he must have been both astonished and afraid; for after his eyes had rested upon the ungainly form of the horse for a moment he walked rapidly to the furthest edge of the roof, his head turned back over his shoulder to gaze at the strange animal.
Dorothy and the Wizard in Oz by Baum, L. Frank View in context
