Global System for Mobile communications (GSM) Training

Global System for Mobile communications (GSM) Training course with hands-on Exercises (Online, Onsite and Classroom Live)

The Global System for Mobile communications (GSM) is the world’s dominant wireless technology.  It’s no exaggeration to state that all wireless technologies that have come since GSM have been impacted by it, at least in a conceptual way.  How does GSM solve the multitude of problems that need to be solved to provide simultaneous services to a large number of mobiles over a large geographical area?  This question, simply stated, forms the agenda of this intensive four-day GSM Training course.

Upon GSM Training or Global System for Mobile communications (GSM) Training course completion, you will be able to identify the components of a GSM network and the protocols that allow them to communicate with each other.  You will be in a position to critically evaluate and compare solutions to specific problems within the rules set forth by GSM.  While GSM is a complex system, rich in details, the GSM Training course will allow you to understand the GSM structures and articulate their interactions.  This, in turn, will enable you to identify good design and optimization strategies as well as performance problems and solution approaches.

Global System for Mobile communications (GSM) TrainingDuration: 3 days
