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.

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.

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 is four times as efficient as GPRS.

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 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.

2G cellular technology combined with GPRS is sometimes described as 2. 5G, that is, a technology between the second ( 2G ) and third ( 3G ) generations of mobile telephony.

GPRS is integrated into GSM Release 97 and newer releases.

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

If SMS over GPRS is used, an SMS transmission speed of about 30 SMS messages per minute may be achieved.

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.

A GPRS connection is established by reference to its access point name ( APN ).

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.

* Slower mobile internet service ( EDGE and GPRS ) is also offered by all mobile phone companies at very low flat rates.

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.

EDGE is standardized by 3GPP as part of the GSM family and it is an upgrade that provides a potential three-fold increase in capacity of GSM / GPRS networks.

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.

Apart from the fact that the full allocated bandwidth of the connection is available to the HSCSD user, HSCSD also has an advantage in GSM systems in terms of lower average radio interface latency than GPRS.

* The GPRS Core Network ( the optional part which allows packet based Internet connections ).

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

However, D-AMPS has been competing against GSM and systems based on code division multiple access ( CDMA ) for adoption by the network carriers, although it is now being phased out in favor of GSM / GPRS and CDMA2000 technology.

WAP and GPRS best supports turn based games and small RPG games.

3G allows in most cases realtime multiplayer gaming and is based on technologies faster than GPRS.

These advertisements would be downloaded via the device's GPRS data connection, and would be targeted based on data inputted to the device.

The Thuraya SG-2520 was released in early 2007, this is a dual-mode handset that also connects to GSM / GPRS services and is based on Windows CE and made by Apsat in South Korea.

The Clubman fleet has problems with its passenger information system, which is based on GPRS and GSM technology, but frequently fails to accurately find its position, resulting in misleading information being displayed to passengers.

As of today, Ukrainian MTS network support various value-added services based on GPRS / EGPRS / EDGE and SMS / WAP / MMS / USSD.

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.

The upload and download speeds that can be achieved in GPRS depend on a number of factors such as:

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

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.

The packet data protocol ( PDP ; e. g., IP, X. 25, FrameRelay ) context is a data structure present on both the serving GPRS support node ( SGSN ) and the gateway GPRS support node ( GGSN ) which contains the subscriber's session information when the subscriber has an active session.

A large majority of the Rogers ' customer base uses its GSM / GPRS / EDGE network, but the main focus for development and new customers has been on its UMTS / HSDPA / EUL 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.

GPRS does this by sending packets to the local mobile phone mast ( BTS ) on channels not being used by circuit-switched voice calls or data connections.

* Nokia 3200b ( RH-31 ) for North America-Operates on GSM 850 / 1800 / 1900 with GPRS and EDGE technology.

* Nokia 3200 ( RH-30 ) for Europe / Asia-Operates on GSM 900 / 1800 / 1900 with GPRS and EDGE technology.

As the maps are downloaded from the internet on the fly so the phone requires a GPRS / UMTS connection.

GPRS and EDGE usually are billed by data traffic volume.

LightSurf's products included the first mobile picture messaging solution in North America ( GSM ), the first mobile picture messaging solution on a GPRS carrier network, the first commercially deployed inter-carrier MMS solution in North America, the highest volume of picture and video messaging in North America and over 400 million media messages shared on Sprint ’ s network ( powered by LightSurf ).
