Abstract: A communication network (ON) including a set of user terminals (UE1, UE2) such as a cellular network or a WLAN includes a system for dynamically controlling spectrum usage. The system includes:
- a sensing functionality (BS1, BS2; UE1, UE2) for sensing spectrum usage within the area covered by said communication network (ON);
- a policy server (PS) configured for producing, as a function of the spectrum usage as sensed, spectrum usage policies for the communication network (ON); and
- a broadcasting arrangement (BS1, BS2; UE1, UE2) for broadcasting the spectrum usage policies to the user terminals (UE1, UE2).
A preferred use of the invention is within the framework of Cognitive Radio systems.

Abstract: A system for scanning frequency spectrum to detect usage thereof, includes an Ultra-WideBand (UWB) receiver (101) configured for performing the scanning action and arranged for co-operation with:
- a Spectrum Usage Estimator module (103) configured for deriving from the scanning performed via the Ultra-WideBand (UWB) receiver (101) information as to usage of individual bands in the frequency spectrum, and.
- a Radio Controller Unit (104) configured for controlling operation of a radio cognitive system as a function of the information as to usage of individual bands in the frequency spectrum as derived by the Spectrum Usage Estimator module (103), whereby the radio cognitive system operates over unused bands in the frequency spectrum.
