Abstract: A spectrum management system includes circuitry that determines available spectrum for a secondary communication system. The available spectrum is determined based on a disturbance tolerance of a primary communication system that is managed by the spectrum management system and a disturbance tolerance of another primary communication system that is managed by another spectrum management system. The circuitry then causes the setting of a spectrum for the secondary communication system based on the available spectrum and whether or not a spectrum request is received from the secondary communication system.
