Introduction:

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.

Audience:

All Personnel responsible for: The planning, design or specification of mobile radio solutions. Supporting TETRA networks or equipment. The evaluation or implementation of TETRA technology. Operating network equipment that interfaces with TETRA equipment

Prerequisites:

Basic Knowledge of Radio and Mobile Network Fundamentals

Customize it:

This 2-3-day Tetra course will be customized to your needs and specifications. Enowireless will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Enowireless, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”, one size fits all, class.
