Through the introduction of sophisticated methods of coding and transmitting data, EDGE delivers higher bit-rates per radio channel, resulting in a threefold increase in capacity and performance compared with an ordinary GSM/GPRS connection.
EDGE can be used for any packet switched application, such as an Internet connection.
EDGE is a superset to GPRS and can function on any network with GPRS deployed on it, provided the carrier implements the necessary upgrade.
EDGE requires no hardware or software changes to be made in GSM core networks.
Evolved EDGE continues in Release 7 of the 3GPP standard providing reduced latency and more than doubled performance e.g. Peak bit-rates of up to 1 Mbit/s and typical bit-rates of 400 kbit/s can be expected.
EDGE/EGPRS is implemented as a bolt-on enhancement for 2.5G GSM/GPRS networks, making it easier for existing GSM carriers to upgrade to it.Mobile operators have invested billions in GSM networks, many of which are already capable of supporting EDGE data speeds up to 236.8 kbit/s.With a software upgrade and a new device compliant with Evolved EDGE (like an Evolved EDGE smartphone) for the user, these data rates can be boosted to speeds approaching 1 Mbit/s (i.e. Many service providers may not invest in a completely new technology like 3G networks.It also enhances the circuit data mode called HSCSD, increasing the data rate of this service.The channel encoding process in GPRS as well as EGPRS/EDGE consists of two steps: first, a cyclic code is used to add parity bits, which are also referred to as the Block Check Sequence, followed by coding with a possibly punctured convolutional code.Enhanced Data rates for GSM Evolution (EDGE) (also known as Enhanced GPRS (EGPRS), IMT Single Carrier (IMT-SC), or Enhanced Data rates for Global Evolution) is a digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM.EDGE is considered a pre-3G radio technology and is part of ITU's 3G definition.This article is about the digital mobile phone technology.For the women's educational support organization, see EDGE Foundation.For the instruction set architecture type called EDGE, see Explicit data graph execution.For other uses of the acronym EDGE, see Edge (disambiguation).
