Abstract: This report describes a new technique for calculating the spectrum space used by existing frequency assignments. The Spectrum Use Measure (SUM) model determines the amount of spectrum used at a given location or the probability that a given location is unavailable for a new assignment. These quantities, stored in a SUM data base, can be used to produce maps, histograms and indices of spectrum use. The SUM technique has been effectively applied to the 17101850 MHz and the 7750-7900 MHz bands. The report concludes that the SUM technique is an effective indicator of spectrum use and recommends that it should be used when evaluating service bands.
