Enhanced Data rates for GSM Evolution ( EDGE ) ( also known as Enhanced GPRS ( EGPRS ), or 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.

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 / 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.

This was expanded over time to include data communications, first by circuit switched transport, then packet data transport via GPRS ( General Packet Radio Services ) and EDGE ( Enhanced Data rates for GSM Evolution or EGPRS ).

General packet radio service ( GPRS ) is a packet oriented mobile data service on the 2G and 3G cellular communication system's global system for mobile communications ( GSM ).

GPRS is integrated into GSM Release 97 and newer releases.

The GPRS system is an integrated part of the GSM network switching subsystem.

; Class A: Can be connected to GPRS service and GSM service ( voice, SMS ), using both at the same time.

; Class B: Can be connected to GPRS service and GSM service ( voice, SMS ), but using only one or the other at a given time.

During GSM service ( voice call or SMS ), GPRS service is suspended, and then resumed automatically after the GSM service ( voice call or SMS ) has concluded.

; Class C: Are connected to either GPRS service or GSM service ( voice, SMS ).

The multiple access methods used in GSM with GPRS are based on frequency division duplex ( FDD ) and TDMA.

GSM / GPRS mobile phone services in the city are provided by Afghan Wireless, Etisalat, Roshan and MTN.

This is largely due to the introduction of GPRS ( General Packet Radio Service ) and EDGE Enhanced Data Rates for GSM Evolution connectivity by the GSM operators.

All existing GSM networks presently offer GPRS services and have introduced of 3G / UMTS.

# The UPS to report its status to the computer it powers via a communications link such as a serial port, Ethernet, GSM / GPRS or USB

To avoid the dependency on Ethernet infrastructure, the UPSs can be connected directly to main control server by using GSM / GPRS channel also.

The electricity meter communicates with a concentrator, and the latter sends the information through GPRS or GSM to the energy provider's server.

* GSM with the GPRS packet switched service combines FDD and FDMA with slotted Aloha for reservation inquiries, and a Dynamic TDMA scheme for transferring the actual data.

* General Packet Radio Service ( GPRS )

* the Global System for Mobile Communications ( GSM ) including GSM evolved radio access technologies ( e. g. General Packet Radio Service ( GPRS ) and Enhanced Data Rates for GSM Evolution ( EDGE ))

It is a version of Nokia's 6600 smartphone for the North American market, featuring all the features of the 6600 such as the VGA camera, MultiMediaCard slot, Bluetooth and color screen, but with a change to the North American GSM frequencies, the doubling of internal RAM, the addition of Nokia's new Pop-Port connector, the inclusion of stereo sound, and a new EDGE capability, effectively giving it double the download speeds of current General Packet Radio Service ( GPRS ) equipped phones.

The RNC connects to the Circuit Switched Core Network through Media Gateway ( MGW ) and to the SGSN ( Serving GPRS Support Node ) in the Packet Switched Core Network.

Fido was the first carrier in Canada to launch a GSM-based network and the first wireless service provider in North America to offer General Packet Radio Service ( GPRS ) on its network.

* General Packet Radio Service ( GPRS ) provides more efficient packet-based data transmission directly from the mobile phone at speeds roughly twice those of HSCSD.

The General Packet Radio Service ( GPRS ) is a packet-switched data transmission protocol, which was incorporated into the GSM standard in 1997.

The terminal discovers its P-CSCF with either DHCP, or it may be configured ( e. g. during initial provisioning or via a 3GPP IMS Management Object ( MO )) or in the ISIM or assigned in the PDP Context ( in General Packet Radio Service ( GPRS )).

The ComfortDelGro taxi booking system, wirelessly connects the taxis using the General Packet Radio Service ( GPRS ) technology via the in-vehicle Mobile Data Terminals ( MDTs ).

* Access Point Name, a setting for the General Packet Radio Service ( GPRS )

# Packet routing functionality ( provided by GGSN in the GPRS / UMTS networks )

* Packet Data Protocol ( PDP ) services for GPRS: providing routing information for GPRS connections

GPRS usage is typically charged based on volume of data transferred, contrasting with circuit switched data, which is usually billed per minute of connection time.

GPRS is a best-effort service, implying variable throughput and latency that depend on the number of other users sharing the service concurrently, as opposed to circuit switching, where a certain quality of service ( QoS ) is guaranteed during the connection.

The GGSN is responsible for the interworking between the GPRS network and external packet switched networks, like the Internet and X. 25 networks.

* 3GPP Technical Specification TS 23. 060 GPRS Service Description describes Location management procedures for the packet switched domain.

Cingular Wireless later offered CDPD under the Wireless Internet brand ( not to be confused with Wireless Internet Express, their brand for GPRS / EDGE data ).

EDGE, like GPRS, uses a rate adaptation algorithm that adapts the modulation and coding scheme ( MCS ) according to the quality of the radio channel, and thus the bit rate and robustness of data transmission.

GPRS data may be sold either as part of a bundle ( e. g., up to 5 GB per month for a fixed fee ) or on a pay-as-you-use basis.

In 2G systems, GPRS provides data rates of 56 – 114 kbit / second.

USB 3G / GPRS modems use a terminal-like interface over USB 1. 1, 2. 0 and later, data formats V. 42bis, and RFC 1144 and some models have connector for external antenna.

The SMS or GPRS data packets sent from UPSs trigger software to shutdown the PCs to reduce the load.

In 2009, the 3G coverage covers most major towns where there is a telephone exchange and either HSDPA or EDGE services within radius ( GSM UMTS maximum allowed range ) with GPRS as basic data coverage.

Enhanced Data rates for GSM Evolution ( EDGE ), Enhanced GPRS ( EGPRS ), or IMT Single Carrier ( IMT-SC ) is a backward-compatible digital mobile phone technology that allows improved data transmission rates, as an extension on top of standard GSM.

This makes HSCSD relatively expensive in many GSM networks and is one of the reasons that packet-switched general packet radio service ( GPRS ), which typically has lower pricing ( based on amount of data transferred rather than the duration of the connection ), has become more common than HSCSD.

Such data can be obtained via the CAN-bus, via direct connections to AVL systems or via open bus systems such as UFDEX that both sends and receives data via SMS or GPRS in pure ASCII text format.

GPRS and EDGE data services are also available.

* GPRS and EDGE data communication

It does this by carrying the subscriber's data from the subscriber's current serving GPRS support node ( SGSN ) to the GGSN which is handling the subscriber's session.

The GGSN converts the GPRS packets coming from the SGSN into the appropriate packet data protocol ( PDP ) format ( e. g., IP or X. 25 ) and sends them out on the corresponding packet data network.
