It is essentially a technological enhancement over GPRS. The data transfer rate reaches up to 236 kilobits per second. Designed to improve second-generation networks, experts classify EDGE as generation “2.75G.”

The advantage of EDGE lies in its ability to operate within the frequency bands occupied by GSM, and in the ease of its implementation in mobile terminals for handset manufacturers. It is a lightweight, easy-to-operate, and relatively inexpensive technology, serving as a temporary solution for upgrading GSM networks: UMTS requires significantly greater investment and changes in the provider’s architecture.
