Description
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 technical questions in short time with reasonable accuracy. You are provided with a comparison of the properties of conventional analogue and new digital PMR systems to help support the decision to introduce a new radio communication system. This unique resource features discussions on critical topics not covered in any other book, such as transmitter switching spectrum, real Doppler situations, and real usable frequency economy. It also discusses alternatives to PMR, such as public cellular systems, and concludes with a look at the future of PMR through the year 2010.
