- duration
- 3 day(s)
- 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.
- Prerequisites
-
- Technical background and some prior exposure to wireless communications.
- Technical background and some prior exposure to wireless communications.
- 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 also 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.
