EDGE is delivering high bit-rates and spectrum efficiency for GSM operators around the world, and is becoming a standard capability of GSM and WCDMA phones. In effect, EDGE enables 3G applications over current GSM networks, and provides seamless services with 3G.
Today, EDGE enables user bit-rates of 250 kbit/s and a latency of 150 ms. This means it can handle four times as much traffic as standard GPRS, increasing the usability of mobile data services, enhancing customer satisfaction and boosting data revenues.
EDGE Evolution, currently being standardized in 3GPP, will improve performance and coverage even further, with bit-rates of up to 1 Mbit/s and latency below 100 ms.
For GSM operators around the world, this makes the business case for EDGE even stronger than it is today – whether or not they have access to 3G spectrum.
