General Packet Radio Service
GPRS

    (GPRS) A GSM data transmission technique
   that transmits and receives data in packets.  This contrasts
   with systems that set up a persistent channel.  GPRS makes
   very efficient use of available radio spectrum, and users pay
   only for the volume of data sent and received.

   See also: packet radio.
