Broadband spectrum surveys in Denver, CO, San Diego, CA, and LosAngeles, CA: methodology, analysis, and comparative results

摘要

The Institute for Telecommunication Sciences (ITS) has performed aset of automated, broadband measurement surveys of spectrum usage inseveral metropolitan areas in the United States across the frequencyrange 108 MHz to 19.7 GHz. The methodology, hardware and software usedto conduct the surveys are described. The survey results are broken downinto separate categories for mobile, point-to-point and radiolocationbands. In mobile bands, maximum, minimum and average levels of usageduring the survey periods are measured. Relatively light usage byterrestrial point-to-point microwave systems is observed. Broadbandoccupancy at relatively levels is shown for radar systems in theradiolocation bands
