    Abstract: An interference detection system in a network identifies a first wireless station that has experienced radio frequency (RF) interference from an unknown source and identifies one or more second wireless stations that have experienced similar interference. A plurality of estimated interference source locations are scored based on a comparison of estimated interference to observed interference at the one or more second wireless stations. A predicted interference source location is identified based on the scored plurality of estimated interference source locations. It is determined whether the unknown interference source is a persistent interference source over a selected time period, wherein the predicted interference source location is identified for each interval in the selected time period. The predicted interference source locations for each interval in the selected time period are retrieved and an aggregated predicted interference source location is calculated based on the retrieved predicted interference source locations.

    Abstract: A device may receive interference data identifying interference associated with sectors provided by base stations, and may filter interference data associated with sectors with passive intermodulation issues and sectors with alarms related to sectors' radio, from the interference data, to generate interference data for a set of sectors. The device may perform an interference analysis on the sectors' physical resource blocks (PRBs) and receiving branches, of the interference data, to generate analysis results, and may determine interference associated with co-located sectors of the set of sectors. The device may identify neighbor sectors based on the interference, and may compare PRBs of the set of sectors with PRBs of the neighbor sectors to generate comparison results. The device may identify a particular sector that is the most impacted sector when compared to its neighboring and co-located sectors, associated with an interference source, based on the comparison results.

    Abstract: In some implementations, a network monitoring system may measure a traffic metric for a first component of a network device. The network monitoring system may determine, based on a trained component monitoring model, that an obtained measurement of the traffic metric for the first component satisfies a criteria associated with the traffic metric pattern. The network monitoring system may compare, based on determining that the obtained measurement satisfies the criteria, the obtained measurement to a corresponding measurement of the traffic metric for a second component of the network device. The network monitoring system may determine that a measurement difference between the obtained measurement for the first component and the corresponding measurement for the second component satisfies a difference threshold. The network monitoring system may perform, based on the measurement difference satisfying the difference threshold, an action associated with the first component.
