After an extensive list of definitions, a listing and brief description is given of a number of communication systems in the 800/900 MHz frequency bands. Modes of propagation are reviewed in depth and the effects of buildings, trees, and other interference are noted. Antenna characteristics and system losses are discussed. A variety of experimentally or theoretically based propagation models, developed to predict radio propagation in land mobile systems, are then examined. After listing and summarizing the major features of the models, the models are compared in terms of the environmental and propagation factors they account for, and in terms of the output information they provide. The median transmission loss predictions of various models are compared for a given base antenna site. A detailed evaluation is provided to evaluate predictions obtained in the following basic situations: smooth terrain between base station and mobile; smooth terrain with a knife-edge obstacle located close to the mobile; and smooth terrain with a knife-edge obstacle at the midpoint of the path. Recommendations on measurement procedures are offered by the Committee on Radio Propagation. Factors affecting the choice of a propagation model for particular applications are discussed
