Course Overview

Course in a Nutshell

The Global System for Mobile communications (GSM) is the world’s dominant wireless technology.  This course was designed to be an intensive tutorial of GSM, together with its enhancements, GPRS and EDGE. While the focus of the course is on over-the-air operations, the course can be modified upon request to expand the emphasis placed on the core network issues and to include or exclude certain topics.


Customize It!

We can customize this course, usually at little to no additional cost, to your unique requirements. For instance, the course can be expanded to four or five days for a more in-depth discussion of GSM, GPRS, and EDGE or to include an overview of UMTS and HSPA. The focus of the course can be shifted from the air operations to the mix of topics of interest to your group.  The course can also be presented at a less technical level for an audience of non-engineers.



Audience / Prerequisites

Aimed At

Engineers, technicians, and others who have some existing background in wireless and require an overview of GSM, GPRS, and EDGE, with principal focus on the radio interface.



Technical background and some prior exposure to wireless communications.


  • "Instructor was everything we could have hoped for and more. Very warm and energetic, informative, and concise. It was a great credit to his ability that the class stayed focused through a lot of very technical information. I had expected to lose a few people along the way but that was not the case. He kept everyone intrigued and alert. Now I can easily instruct other team members in their assignments with a good feeling that they have a sound basis and understanding of the subject matter." – Mike Augustis, Sr. Embedded Software Engineer, Lockheed-Martin
