Abstract
A method for localizing interference uses data available to wireless communication networks to determine probabilities of a source of external interference being located at a plurality of predetermined locations. In a heterogeneous network, data from sites using omnidirectional antennas can be combined with data from multi-sector sites to accurately locate a source of interference.
Claims19
A method for locating a source of interference affecting a wireless telecommunications network, the method comprising:
- generating a first probability map that indicates probabilities of the source of interference being disposed in respective geographic locations;
- receiving interference data for at least one omnidirectional antenna that is disposed in a location covered by the map;
- generating a contour map of interference levels using the received interference data;
- and
- generating a second probability map by re-assigning probability values of the first probability map according to contours of the contour map,
- wherein generating the contour map includes generating a plurality of bounded shapes, each shape having a perimeter line that represents a particular level of interference.
A wireless telecommunications system comprising a spectrum analysis server configured to locate a source of interference external to a wireless telecommunications network, the spectrum analysis server comprising a processor and a non-transitory computer readable medium with instructions stored thereon which, when executed by the processor, perform the following steps:
- generating a first probability map that indicates probabilities of the source of interference being disposed in respective geographic locations;
- receiving interference data for at least one omnidirectional antenna that is disposed in a location covered by the map;
- generating a contour map of interference levels using the received interference data;
- and
- generating a second probability map by re-assigning probability values of the first probability map according to contours of the contour map,
- wherein generating the contour map includes generating a plurality of bounded shapes, each shape having a perimeter line that represents a particular level of interference.
