General Packet Radio Service (GPRS) is a packetized voice data network’s virtual global system for voice communications over the global low-speed mobile communication network. GPRS was developed by European Telecommunications Standards Institute, in response to the previous CDPD and i-style packet-switching cellular technology. It was initially designed for distribution using fixed networks only, but has since been extended to work over any medium or carrier signal, including mobile broadband. The primary advantage of using GPRS is that it provides a competitive edge over other competitive systems such as CDPD, which use the analog voice band and transmit voice traffic via the internet instead of the voice data network, resulting in lower voice costs for users.
