Abstract
Transmitter localization and signal mapping may be accomplished by receiving measurement data from a plurality of nodes, the measurement data including a signal strength value and a geographic location for the signal strength value, triangulating the plurality of measurements using triangulation, and establishing at least one contour representing a level of signal strength. A system may receive measurement data from a plurality of user equipment, and use that data to localize an interference source and create a contour map.
Claims18
A method for characterizing interference detected by distributed measurement nodes performed by a network resource controller in a wireless communication system, the method comprising:
- collecting signal data from a plurality of measurement nodes, the signal data including a signal strength measurement and a geographic location for the signal strength measurement;
- establishing a triangulated mesh of the geographic locations of the plurality of measurement nodes using Delaunay triangulation to create a plurality of triangles;
- establishing at least one contour by connecting a plurality of coordinates along sides of the plurality of triangles;
- and localizing a source of the interference by averaging the plurality of coordinates to determine a single geographical coordinate value that corresponds to a location of the source of interference.
A wireless communications system, the system comprising:
- a network resource controller coupled to a backhaul portion of the communications system;
- and
- a plurality of base stations that transmit signal data to the network resource controller, the signal data including a signal strength value measured by a node chosen from the plurality of base stations and user equipment (UE) attached to at least one of the plurality of base stations, the signal data further including a geographic location where the signal strength value was measured,
- wherein the network resource controller includes a processor that performs the following process steps:
- establishing a triangulated mesh of the geographic locations of the signal data using Delaunay triangulation to create a plurality of triangles;
- establishing at least one contour by connecting a plurality of coordinates along sides of the plurality of triangles;
- and localizing a source of the interference by averaging the plurality of coordinates to determine a single geographical coordinate value that corresponds to a location of the source of interference.
