A method is presented for quantifying and graphically portraying the extent of use of a frequency band by existing radiocommunication systems. The spectrum use factor quantifies the resources used in a frequency band at a specific location and is defined as the fraction of the total spectrum resources in a frequency band used by existing radiocommunication systems. A computer model calculates the spectrum use factor (SUF) at evenly spaced points in the vicinity of existing transmitters and receivers. The model aggregates the effects of all transmitters and receivers within a geographic area (such as a city, a state. or the continental United States) and creates data files of SUF values from which shaded maps, bar graphs, and indices can be derived.<>
