This practical new book is written for mobile communication professionals who are involved in the planning, design, testing, installation, maintenance, sales and marketing of digital professional mobile radio (PMR) equipment and systems. Written by one of the key developers of PMR, this essential reference provides comprehensive coverage of digital PMR systems and includes advanced tools which help skilled practitioners solve difficult technical questions in short time with reasonable accuracy. Offering unique insight from the author's years of experience working with this technology, the book presents a comparison of the properties of conventional Analogue and new digital PMR systems. Moreover, it features critical topics not covered in any other resource, such as transmitter switching spectrum, real Doppler situations, and real usable frequency economy.
