Course Overview

Course in a Nutshell

Intended as a follow-on to our TETRA Overview course (“TETRA 1”), this course should be scheduled after some time has elapsed since TETRA 1. Building on the knowledge and skills acquired in TETRA 1, this course will help you identify the performance issues with your network and how changes to the TETRA network will impact its performance.
Unlike courses that are presented in the “death by PowerPoint” format, we will employ lecture interspersed with discussion of your questions related to your implementation, discussion of your TETRA configuration and settings, hands-on exercises, and example troubleshooting scenarios and solutions.


Customize It!

Let us know your network architecture and performance challenges and we’ll tailor our course to your specific requirements. The topics can be added/excluded and the course duration shortened/lengthened as needed.
