GPRS and network
EDGE is a superset to GPRS and can function on any network with GPRS deployed on it, provided the carrier implements the necessary upgrade.
The new GPRS network installed by the Scandinavian company allows faster and permanent connectivity for all mobile users, as well as providing high-speed picture and video messaging for owners of the new range of multi-purpose hand-sets.
The GPRS system is an integrated part of the GSM network switching subsystem.
In order to set up a GPRS connection for a wireless modem, a user must specify an APN, optionally a user name and password, and very rarely an IP address, all provided by the network operator.
This refers to the setting up of new services, such as GPRS, MMS and Instant Messaging for an existing subscriber of a mobile phone network, and any gateways to standard Internet chat or mail services.
In 2005 Orange France becomes the first operator to use a national broadband network for mobile phones combining EDGE, which covers 95 % of the population, 3G, which covers 60 %, and GPRS ( low bandwidth Internet ), which covers 98 %.
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.

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 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 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.
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.
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.

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.
