Course Overview

Course in a Nutshell

This comprehensive 7-day course includes an introduction to RF (Part 1) followed by in-depth discussion of TETRA (Part 2). It’s aimed at technicians and others with limited exposure to Telecommunications (especially RF) and Mathematics. We will teach this course in a manner that enables easy understanding through the use of diagrams, examples, and easy-to-follow explanations.

 

Customize It!

We can customize this course to your technical requirements, usually at little to no added cost. The course can be shortened or lengthened and its content tailored to suit the needs of your group.

 

Audience / Prerequisites

Aimed At

This course is aimed at technicians and others who need a “user friendly” but fairly in-depth course on TETRA.

 

Prerequisites

Some prior exposure to RF will be helpful though not required.
