This is a layer 3 tunneling protocol.
Gprs diagram. It extends features to second generation gsm network by providing data rates from 9 6 to 171 kbps. Sometimes it is more cost effective to simply augment the existing system rather than completely creating a newer one. It is now maintained by the 3rd generation partnership.
Gsm gprs module is used to establish communication between a computer and a gsm gprs system. Gsm modem transmits and receives the data. From the diagram given above it can be seen that the gprs network architecture added some extra elements to the gsm network to enable it to cary the packet data.
Global system for mobile communication gsm is an architecture used for mobile communication in most of the countries global packet radio service gprs is an extension of gsm that enables higher data transmission rate gsm gprs module consists of a gsm gprs modem assembled together with power supply. Gprs tunnelling protocol is the defining ip based protocol of the gprs core network. This is the case with gsm and gprs.
Gtp is the protocol used between the sgsn and ggsn using the gn interface. Modem sim300 is a tri band gsm gprs engine that works on frequencies egsm 900 mhz dcs 1800 mhz and pcs 1900 mhz. Gprs also gave mobile phones the ability to surf the internet at dial up speeds through wap enabled sites.
Gprs architecture is similar to gsm network but it has extra entities which allow packet data transmission. This gps based vehicle tracking system uses sim300 gsm modem refer fig. Gsm network allows various users to use the same interface resource by sharing.
Gprs attempts to reuse the existing gsm network elements as much as possible but to effectively build a packet based mobile cellular network some new network elements interfaces and protocols for handling packet traffic are required. Gprs devices can be data only such as a computer browsing the internet they can be single mode such as a gsm telephone or they can be dual mode able to access either or both the gprs and gsm channels. General packet radio service gprs is a packet oriented mobile data standard on the 2g and 3g cellular communication network s global system for mobile communications gsm.
