Introduction
Abstract
The concept of land mobile service is reviewed. The conventional terrestrial mobile radio systems, including dispatch and radiotelephone are described. The more advanced cellular system is described, and the way it mitigate the many problems currently plaguing the conventional terrestrial mobile service are discussed. The concept of the Land Mobile Satellite Service is introduced. How a satellite system can augment the terrestrial system for a truly ubiquitous coverage is shown. The operation of a multiple beam satellite system is explained in terms of its similarities with the terrestrial cellular systems. The potential frequency spectrum availability for the LMSS in the United States is included.
