SUM Land Mobile Model: Application of the Spectrum Use Measure to the Land Mobile Service

摘要

The Spectrum Use Measure (SUM) technique quantifies and graphically depicts the amount of spectrum resources used in a region within a frequency band. The SUM technique was originally developed to calculate spectrum use for a fixed system. The report describes the extension of the SUM model to calculate spectrum use for land mobile systems and the application of the land mobile model to the 406.1-420 MHz frequency band. An enhancement to the model that greatly reduces the run time is also discussed. The report concludes that the SUM concepts are applicable to land mobile systems and recommends extension of the model to additional services and frequency bands.
