EDGE

EDGE, short for Enhanced Data Rates for GSM Evolution, is a GSM-based protocol that provides theoretical speeds up to 384 Kbps. It is a 2.5G technology that is sometimes referred to as 3G because of its higher speed. It is not yet as widely used as GPRS, but is gaining support. For example, AT&T has deployed EDGE on its GSM networks in the USA, reaching speeds of around 90 Kbps in practice. Smartphones such as the Nokia 9300 and Nokia 6620 support EDGE.
