This single book covers what you need to know about analog and digital land mobile radio systems to develop and sell systems, mobile radios and services. It explains the different types of public and private land mobile radio technologies including iDEN, EDACS, TETRA, APC025, MPT1327, LTR and others. It describes the key applications, such as group call, voice broadcast and short messaging, that help drive the rapid customer growth for these systems. This book is important to managers, technicians and salespeople who want to understand how the technologies work and the key features they can offer without having to use complicated mathematical references.

TERRESTRIAL TRUNKED RADIO (TETRA). ENHANCED DIGITAL ACCESS COMMUNICATIONS SYSTEM (EDACS). INTEGRATED DIGITAL ENHANCED NETWORK (iDEN). APCO 25. GENERAL LAND MOBILE RADIO.
Commercial Trunked Radio is currently in operation in over 61 countries worldwide, and it will continue to grow as more and more countries realize the enormous benefits to their economies.
In some countries, we refer to trunked radio as Specialized Mobile Radio, Enhanced Specialized Mobile Radio, or Public Access Mobile Radio, just to name a few. Recognizing the many different terms for essentially the same basic service, be it analog or digital, IMTA prefers to use the term Commercial Trunked Radio.
What characterizes this type of radio system apart from traditional LMR systems is not so much the technology but the nature of exclusive licenses that allow operators to operate as a carrier. Operators of private internal systems often have little incentives to upgrade equipment, maximize capacity, and develop larger coverage areas. On the contrary, commercial trunked radio operators have economic incentives to operate efficiently, expand coverage areas, and to offer an array of different services (voice & data) and more.
Today there are over 8,000,000 units in service worldwide. We use this particular measure for analysis since a typical customer may order and maintain eight radios on average. The overall growth of "units in service" is expected to increase very dramatically as we see more and more digital systems coming on line.
We are extremely pleased to have been invited to help in the preparation of this worthy endeavor, and are pleased to be looked upon as a truly international association representing the Commercial Trunked Radio Industry worldwide. This book is truly a "must read" for anyone considering entering this highly lucrative business.
