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.

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.

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

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.

Modern web-based editing systems can take video directly from a camera phone over a GPRS or 3G mobile connection, and editing can take place through a web browser interface, so, strictly speaking, a computer for video editing does not require any installed hardware or software beyond a web browser and an internet connection.

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.

Within the GPRS core network standards there are a number of interfaces and reference points ( logical points of connection which probably share a common physical connection with other reference points ).

" GPRS connection timer " registers the time for each session.

Both require a WiFi, 3G, EDGE or GPRS connection.

Multiplayer functionality is achieved through Infrared, Bluetooth, GPRS, 3G, Wi-Fi, AI, MMS, or Wireless LAN connection.

* An Internet Service Provider which provides network access via common modem or modem-like devices ( be it PSTN, DSL, cable or GPRS / UMTS ) can have one or more NAS ( network access server ) devices which accept PPP, PPPoE or PPTP connections, checking credentials and recording accounting data via back-end RADIUS servers, and allowing users access through that connection.

* GPRS mobile data service, provides high speed connection and data transfer rate

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

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

On phones with built-in Wi-Fi ( tested on Nokia E51, E63, E66, E71, and N95 8GB ), the Nokia application does not allow a Wi-Fi access point to be used for the data connection, only GPRS access points are allowed, allowing the possibility of revenue sharing between Nokia, the Radio stations and GPRS network operators.

Telecommunication is at par with other neighboring municipalities using cellular phones, internet via GPRS ( but Internet connection via satellite is now available located at Purok Talisay-B, Aras-asan, Cagwait, Surigao del Sur ), and cable television are available.

* For GPRS & 3G, date and time of connection, IMSI, IP address assigned.

She is now on the move, and her laptop is downloading her emails using the GPRS connection on the mobile:

Once this merging is complete, the downloading of her email continues totally unaffected, but instead of using the expensive and slow GPRS connection, it is now using the newly established WLAN connection.

It introduces a new technology not found in GPRS, Incremental Redundancy, which, instead of retransmitting disturbed packets, sends more redundancy information to be combined in the receiver.

GPRS uses four coding schemes ( CS-1 to 4 ) while EDGE uses nine Modulation and Coding Schemes ( MCS-1 to 9 ), of which the first four have similar performance ( but not equal ) to GPRS.

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

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 %.

The GPRS core network is the central part of the general packet radio service ( GPRS ) which allows 2G, 3G and WCDMA mobile networks to transmit IP packets to external networks such as the Internet.

Primarily it is the protocol which allows end users of a GSM or WCDMA network to move from place to place while continuing to connect to the Internet as if from one location at the Gateway GPRS support node ( GGSN ).

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.

A GSN is a network node which supports the use of GPRS in the GSM core 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.

When the station is attached to the GPRS network, the SGSN keeps track of which routing area ( RA ) the station is attached to.

* GPRS Tunnelling Protocol, a group of protocols which carry GPRS data information over the UMTS and GSM networks

Unlike either the Palm i705 and the Palm VII ( which both could only make data connections over the Mobitex pager network ), downloads and uploads were done using comparatively-fast GPRS connections.

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

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 ).

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.

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.
