Abstract
A system for mitigating the effects of interference in an unlicensed RF band for point to point data transmissions comprises a multibeam antenna locating interference with transmission to and from data transmission subscribers. A scanner determines the frequency, bandwidth and any periodicity of the interference. Separate scanners can be used for each antenna beam. Nulls are generated in the data transmission antenna pattern in the direction of the interference during periods of interference. Communications with subscribers in a direction of the interference is carried out using a different channel or is scheduled around the interference occurrences. Alternatively, such subscribers are directed to establish data transmissions with an alternate hub antenna.
