TETRA Air Interface Training

This TETRA Air Interface Training course has been designed to compliment TETRA System Overview. In just two days this TETRA Air Interface Training course covers all aspects of the TETRA Air Interface.

Customize It:

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.
