Spectrum occupancy results from several surveys

This paper presents spectrum occupancy results from spectrum surveys conducted at three locations: Denver, CO,Table Mountain near Boulder, CO, and Point Loma, near San Diego, CA. Equipment setups are described along with the measurement algorithms used to measure various emission types. Various statistical graphs, M4 statistics plots and FS-CCDF plots, as well as time vs. frequency or waterfall plots give different representations of the data. Results are shown for a land-mobile radio band and a radar band. Five bands in total will be shown during the presentation.
