Considerations in the choice of propagation models for land mobile radio planning and simulation

Presently available propagation models offer a wide range of technical capabilities, computational complexity, and cost. The radio planner is faced with conflicting requirements for accurate results and limited time, experience, and computer and data resources with which to produce them. The author identifies factors to be considered in choosing what type of model and associated databases are most appropriate to different planning objectives. Criteria discussed include the functional requirements needed to support design objectives, accuracy and validity, computational resource and database requirements, development and application costs, and the degree of generality expected of the results
