Enhanced Data for Global Evolution.
An upgrade for GSM/GPRS networks that triples data rates (speed) over standard GPRS.
See: GPRS
EDGE is used automatically when both the phone and network support it. EDGE phones will automatically revert to the slower GPRS standard when EDGE service is not available.
Although many EDGE phones and devices are theoretically capable of up to 236 Kbps, most EDGE networks are only configured to allow up to 135 Kbps, to conserve spectrum resources. Real-world data rates are usually lower than the maximum.
Because it is based on existing GSM technology, EDGE is a smooth upgrade for GSM network operators. It also works within existing spectrum, making it ideal for countries without dedicated 3G spectrum, such as the US.
Although EDGE works at a low level within the GSM standard that includes voice, the main benefit is to increase GPRS data rates. GPRS operating over EDGE is called EGPRS. |
