GPRS | GPRS - >General Packet Radio Service. A packet-switched technology that enables high-speed wireless Internet and other data communications. GPRS offers a tenfold increase in data speed over previous technologies, up to 115kbit/s (in theory). Typical real-world speeds are around 30-40 Kbps. Using a packet switching, subscribers are always connected and always on-line.GPRS is considered a 2.5G technology.
