Course Overview

Course in a Nutshell

This course will equip you with the understanding of TETRA principles, functionality, and procedures that you need to be able to operate, maintain, and troubleshoot your TETRA network. Unlike courses that are presented in the “death by PowerPoint” format, we will employ lecture interspersed with interactive diagrams, discussion of participant questions related to their implementation, example calls made with the clients handsets on your network, and discussion of your TETRA configuration and settings.

 

Customize It!

Let us know your network architecture and what you are trying to achieve from this course and we’ll tailor our course to your specific requirements. The topics can be added/excluded and the course duration shortened/lengthened as needed.

Audience / Prerequisites

Aimed At

RF personnel with limited exposure to digital RF modulation and TETRA.

 

Prerequisites

Some prior exposure to RF, wireless, telecom, or IT will be helpful.
