GPRS (General Packet Radio Service)

GPRS or General Packet Radio Service, uses Internet-style packet based technology that lets you stay permanently connected to the Internet - but it only uses the radio link for the duration of time that it transfers data. GPRS creates new opportunities for network operators in the form of new services and sources of income. Since the user is constantly online, it is most likely that operators will only charge for the amount of data transferred.

GPRS provides a virtual constant connection and the speed needed for satisfactory Internet usability. Furthermore, GPRS allows for simultaneous voice and data communication, so one can receive incoming calls or make outgoing calls while in the midst of a data (WAP) session. GPRS compliments rather than replaces the current data services available through today's GSM digital cellular networks such as circuit-switched data and Short Message Service (SMS). GPRS is a vital step in the ongoing development of high-speed mobile voice and data communications.
