Definition:
GPRS uses Radio Frequency wireless transmission between the user and the Base Transceiver (transmitter-receiver) Station to provide data transmission at speeds up to 115 KBPS-Kilo (thousands) Bits Per Second. This adds 48 bytes of header overhead to each data packet, which is substantial for voice-over-IP applications that transmit data packets with a small payload. GPRS also defines a Quality of Service (QoS) profile for each user with attributes for precedence, delay, reliability, peak and mean throughput classes.
