Introduction to Digital Professional Mobile Radio

If you are involved in the planning, design, testing, installation, maintenance, sales, or frequency management of digital PMR equipment and systems, this first-of-its-kind book is a smart choice. Written by one of the key developers of PMR, this essential reference provides comprehensive coverage of digital PMR systems, including the standards APCO 25, TETRA and DIIS and the proprietary systems ASTRO, EDACS, iDEN, MOBITEX II and TETRAPOL. Offering unique insight from the author’s years of experience working with this technology, the book helps you gain a solid understanding of the transition from analogue to digital PMR. It provides you with methods for estimation coverage distance and bandwidth for digital PMR systems.

Moreover,the book includes advanced tools which help you solve difficult technicalquestions in short time with reasonable accuracy. You are provided with acomparison of the properties of conventional analogue and new digital PMRsystems to help support the decision to introduce a new radio communicationsystem. This unique resource features discussions on critical topics notcovered in any other book, such as transmitter switching spectrum, real Dopplersituations, and real usable frequency economy. It also discusses alternativesto PMR, such as public cellular systems, and concludes with a look at thefuture of PMR through the year 2010.
