Exploring GPRS and EDGE

Overviews of two important technologies are provided: General Packet Radio Service (GPRS) and Enhanced Data Rates for Global Evolution (EDGE). These technologies are essential for providing a cost effective network solution to enable the wireless web. This course covers the network architecture, components and basic operations of GPRS/EDGE networks and provides an understanding of the various types of handsets and their capabilities. The radio network is explored, including the features designed to efficiently use the limited radio spectrum in addition to the way limited radio resources are shared among numerous users. The core network is discussed in detail, including an investigation of the IP mobility solution, plus a quick look at the various interface protocols. By the conclusion of the course, the student will have a good understanding how existing networks will evolve to support packet data services.

Learning Objectives

After completing this course, the student will be able to:
• List the capabilities and limitations of GPRS and EDGE
• Step through the process of upgrading the GSM network to support GPRS/EDGE
• Sketch the network architecture of GPRS/EDGE
• Identify the enhancements required in air interface to achieve higher data rates of GPRS/EDGE
• Describe mechanisms of sharing resources (slots) among GPRS/EDGE users
• Step through the mobility scenarios of GPRS/EDGE

Intended Audience

This course is intended for individuals seeking an overview of the GPRS and EDGE technologies and capabilities. The discussion of GPRS and EDGE is at a high level which makes it suitable for personnel in management, network planning, deployment and operations.
