Customize It:

  • If you are familiar with some aspects of TETRA Air Interface, we can omit or shorten their discussion.
  • We can adjust the emphasis placed on the various topics or build the TETRA Air Interface course around the mix of technologies of interest to you (including technologies other than those included in this outline).
  • If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the TETRA Air Interface course in a manner understandable to lay audiences.

Audience/Target Group:

  • Engineers and technical professionals involved with PMR or PAMR systems require a detailed coverage of the TETRA air interface and its operation.


  • TETRA System Overview, or equivalent knowledge of TETRA systems, is a pre-requisite for this course.
