GSM System Engineering Training

GSM System Engineering Training


GSM System Engineering Training Course Powered by ENO

This two-day GSM System Engineering Training 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.

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
