Radio Mobile is a tool to help in the elaboration of radio communication networks. Therefore Radio Mobile evaluates if a radio link is possible between two given sites, and provides the performance of that link taking into account:

1. The radio equipment characteristics set in 'Network properties > systems' and 'Unit properties',
2. The radio wave propagation theory (using the US Institute for Telecommunications Science (ITS) propagation prediction model, better known as the Longley-Rice model (Notes 1 and 2)).

The implemented propagation model in Radio Mobile has portions of the Longley-Rice model (ITM).
The propagation model is split up in to parts from which some are conditional.

Radio Mobile will determine if a radio link is line of sight or not. In case of line of sight a 2-ray calculation will be used. In case of a obstructed path the ITM model is applied. To determine a line of sight the clearance of the fresnel zone is determined.

As a part of the ITM model a correction can be applied for the to be expected clutter on the receiver location or in the target area. In addition to the general ITM model Radio Mobile enables the user to select the default global clutter correction or a more sophisticated clutter factor correction is applied that is based on the evaluation of the radio path.

This method is described in detail in 'Use of Land Cover'
