Title: Good book
Review: I'm a technical writer and occasionally write manuals for a telecom client in Europe. This book was a good help and provided a well-rounded coverage for TETRA. It seemed to provide most of the information that I was looking for.There were a few things that I was hoping to find (like a chart of the European RF spectrum, and more information on air interface encryption), but the book had 95% of everything else I needed.The book automatically gets five stars since it's basically the only TETRA book of its kind out there. If you need a good, well-rounded primer on TETRA, this book would be a good choice.
