Abstract: A Personal Communications Service (PCS) System is described. The frequency control system (30) allows PCS systems to coexist in the same frequency band as Private Operational Fixed Microwave Service (POFS) systems without mutual interference. This system (30) also controls frequency usage within a PCS system to eliminate interference from within the PCS system. This interference elimination system combines theoretical radio frequency interference analysis with measurements of actual frequency usage and allows for efficient and coordinated dynamic frequency allocation planning and management. To control frequency assignment and eliminate interference, the system (30) employs several mechanisms including an intersystem interference analysis, an intrasystem interference analysis, a channel use verification (CUV) procedure, and a measured data analysis (MDA).

Abstract: A frequency agile sharing technology (FAST) system for controlling frequent usage in a communications system is disclosed. Specifically, a frequency agile sharing technology system of controlling frequency usage and eliminating interference for use with a Personal Communications Service (PCS) System is described. The frequency control system allows PCS systems to coexist in the same frequency band as Private Operational Fixed Microwave Service (POFS) systems without mutual interference. This system also controls frequency usage within a PCS system to eliminate interference from within the PCS system. This interference elimination system combines theoretical radio frequency interference analysis with measurements of actual frequency usage and allows for efficient and coordinated dynamic frequency allocation planning and management.
