What is a coverage plan?

Predicting radio coverage area is an important aspect in the design of a land mobile radio system and proper placement of the base station(s).

If the earth were a perfectly smooth sphere, with equal signal attenuation in all directions, such predictions would come down to a simple formula and the plot of the coverage area would be a perfect circle.

In some locations, the terrain might approach that of a smooth sphere. However, much of the earth involves very irregular terrain, from gently rolling hills to very rugged mountains. In order to achieve any significant degree of accuracy in the prediction of radio coverage, the terrain of the coverage area must be taken into account. This involves such a tremendous amount of calculations that computer programs have been developed to handle the task. The Egli model, the Bullington model and the Longley-Rice model are the three most commonly used range-prediction models.
