Who Should Attend:

Engineers, technicians, and technical managers with technical backgrounds but limited wireless experience.

Prerequisites:

Basic technical mathematics

Customize it

This 2-3-day GSM System Engineering course will be customized to your needs and specifications. Enowireless will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Enowireless, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”, one size fits all, class.

Course Description:

This two-day seminar provides a solid grounding in principles of basic GSM system design and RF engineering. Propagation, antenna systems, and traffic engineering principles are thoroughly introduced. Finally, GSM system design, growth, and performance considerations are explored each student receiving example files on disk.

Course Objectives:
