A method for locating a source of interference external to a wireless telecommunications network, the method comprising:
- receiving signal strength measurement data for measurements taken by a plurality of cellular antennas of multi-sector cell sites;
- determining that an external interference signal is present in the measurement data;
- establishing a grid of pixels that represents an area associated with the plurality of cellular antennas;
- determining respective first signal strength values for the pixels in the grid;
- and
- determining respective probability values for the pixels in the grid by comparing the signal strength measurement data to the first signal strength values.
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:
- receiving signal strength measurement data for measurements taken by a plurality of cellular antennas of multi-sector cell sites;
- determining that an external interference signal is present in the measurement data;
- establishing a grid of pixels that represents an area associated with the plurality of cellular antennas;
- determining respective first signal strength values for the pixels in the grid;
- and
- determining respective probability values for the pixels in the grid by comparing the signal strength measurement data to the first signal strength values.
