GPRS Overview
3-Day Course

GPRS (General Packet Radio Service) is a high-speed packet-data service designed for use in GSM. GPRS provides an effective utilization of limited radio resources, and supports volume based charging, ideal for bursty traffic transmission. GPRS technology concentrates on interworking with IP based networks like the public Internet and Local Area Networks.

This course describes the necessary changes for a successful implementation of GPRS on a GSM network. A well-structured overall description of this new bearer service is provided in this course.
