General Packet Radio Service (GPRS) is an
enhancement to existing GSM and TDMA networks that introduces packet data
transmission, enabling "always on" mobility. This means that
users can choose to be permanently logged on to e-mail, Internet access
and other services, but do not have to pay for these services unless
sending or receiving information. When EDGE is added to GPRS, these data
rates will increase up to 384kbit/s.
GPRS will be implemented by adding new packet data nodes and upgrading
existing nodes to provide a routing path for packet data between the
mobile terminal and a gateway node. The gateway node will provide
interworking with external packet data networks for access to the Internet
and intranets.
