40246 «GPRS/EDGE Overview»

Course Code




This is an introduction course to General Packet Radio Service (GPRS) and its evolution Enhanced GPRS (EGPRS) or Enhanced Data Rates for GSM Evolution (EDGE).  The GPRS introduces packet switching and services in GSM/EDGE/WCDMA mobile networks of today.

The GPRS/EDGE basic course provides basic concepts in various areas of the network, both in the radio technology (GSM & WCDMA including EDGE & HSPA) and the core network. Topics covered in this course are such as network architecture, traffic flows, and node level features including transport technologies.


Learning objectives

On completion of this course the participants will be able to:

  • Understand the evolution need of cellular packet data technology

Target audience

The target audience for this course is:

Engineers and technicians that are working with GSM/WCDMA wireless technology The course can easily be adapted to other needs (e.g. marketing people).



The participants should have successfully completed the course, “GSM Overview” or have equivalent knowledge


Duration and class size

The recommended length of the course is 2 days. The maximum number of participants is 16. However it is easy to adapt the course length to the actual needs, thanks to the modular structure.


Learning situation

This course is based on theoretical instructor-led lessons given in a classroom environment.
