What is GPRS?

GPRS known as General Packet Radio Service is used mostly in Europe and Asia. GPRS is used most commonly for cell phones..You can send and receive emails using GPRS and browse the Internet.General Packet Radio Service is a radio technology for GSM networks that adds packet-switching protocols, shorter set-up time for ISP connections, it also offers the possibility to charge by amount of data sent rather than connect time.It is a new non-voice value added service that allows information to be sent and received across a mobile telephone network. GPRS is NOT related to GPS (Global Positioning System), a similar acronym that is often used in mobile contexts. Allowing information to be transmitted more quickly, immediately and efficiently across the mobile network, GPRS may well be a relatively less costly mobile data service.

GPRS is part of a series of technologies that are designed to move 2G networks closer to the performance of 3G networks. The key characteristic of a 3G network is its ability to transfer large amounts of data at high speed (up to 2 Mbps), enabling applications like video calling, video downloads, web browsing, email, etc. By increasing the speed of a 2G network, some of these applications become possible, e.g. web browsing and sending or receiving emails with large attachments. These technologies are called 2.5G and include enhancements to the CSD technology, such as HSCSD and EDGE.

GPRS offers much higher data rates than GSM and can be combined with 3G technologies such as EDGE (Enhanced Data-Rates for GSM Evolution) to give even higher bit-rates. It offers many benefits for customers and network operators: such as volume (rather then time) dependent billing and more efficient use of network resources.

WAP and SMS can also be sent using GPRS and individuals working with GPRS need to learn and understand how the mobile stations, the air interface, network architecture, protocol structures and signaling procedures must be modified.
