Abstract: This. report is a spectrum resource assessment of the 7125–8500 MHz band. Included is information on frequency allocations, technical standards, spectrum usage, and identification of spectrum-management issues pertaining to this band. The spectrum-management issues addressed were identified, based on band use, for the last five years, for peacetime applications along with expected band use as a result of the Final Acts of WARC-79. (Emergency and/or wartime applications in this band will be the subject of a subsequent assessment.) Recommendations are made to improve the ·current spectrum-management process to ensure efficient use of this band in the future. Recommendations include modifying certain technical standards, developing sharing criteria among several of the services using this band, and developing a frequency assignment model for fixed operations. Preparation for the upcoming Space WARC, as it pertains to this band, is also discussed.
