Course Overview

Course in a Nutshell

TETRA networks exist in many countries to meet the specialized communications requirements of the public safety community.  While less widely deployed than other technologies, TETRA is an important component of the world-wide mobile communications infrastructure.

In this course, you will learn how the TETRA architecture compares with that of other technologies, helping you identify its strengths and limitations vis-à-vis particular applications.  You will also study the TETRA air interface in a good deal of depth.  TETRA includes some unique capabilities aimed at the public safety community, e.g., it can provide immediate, simultaneous connectivity to a subgroup of users, while maintaining their communications private from the larger organization.   Upon completion of this course, you will have a good understanding of TETRA’s unique functionality as well as the design and optimization challenges posed by it.

 

Customize It!

Customize the course to your specific needs at little-to-no additional cost. We offer distinct versions of this course tailored for audiences such as network design and optimization engineers, equipment or application designers, and less technical audiences such as management, sales/marketing, and operations/support personnel.

Audience / Prerequisites
