The general packet radio service(GPRS) permits packet data to be transmitted and received across a portable network (GSM). GPRS can be an expansion to the GSM network to offer 3G assistance. GPRS has been intended to permit clients to associate with the Internet. GPRS was set up by the European Telecommunications Standards Institute (ETSI). GPRS gives information rates of 56–114 kbit/sec. It gives moderate-speed data transfer, by utilizing unused time-division multiple access (TDMA) channels.
