As mentioned in the previous points, EDGE has the data transfer, for example, could EDGE technology is three times faster than GPRS technology. That is, if the cellular subscriber wants to download MMS messages using GPRS technology takes tens of seconds, but with EDGE technology, it only takes a few seconds.
Another advantage, if the GPRS technology having data transfer capability up to 114 Kbps, EDGE technology capable of supporting data, multimedia services up to 384 Kbps. EDGE is a new designation for the GSM 384. This technology is called GSM 384, because it has a data transmission capability up to 384 Kbps.
According to the World GSM Association, EDGE and even can reach speeds up to 473.8 kbps. With EDGE, operators can provide mobile data communications service with higher speeds than GPRS, which is only capable of GPRS data transmission speeds of about 25 Kbps. So also when compared to other platforms, the ability to reach 3-4 times the speed of EDGE access telephone lines (usually around 30-40 kbps) and almost two times the speed of CDMA 2000 1x, which is only about 70-80 kbps. About the services provided this technology, namely third-generation service applications namely high quality streaming audio, streaming video, online games, high speed downloading.
