摘要： Remote detection of interference generated by Passive Inter-Modulation (PIM) may be performed by determining intermodulation product information for a plurality of transmitters, receiving downlink power information of the plurality of transmitters, determining, using the intermodulation product information and the downlink power information, a Weighted Downlink Power (WDP) signal for an intermodulation product, and determining, using the WDP signal and uplink interference information, a PIM Detection Assessment (PIMDA) score of the intermodulation product, the value of the PIMDA score corresponding to interference generated by PIM. The WDP signal includes a plurality of expected power values. The remote detection of the interference generated by PIM may be performed by a wireless telecommunications system comprising a receiver and a processor, wherein the uplink interference information is of the receiver.

摘要： Anomalies at nodes of a wireless network can be detected by receiving performance measurement (PM) data for a plurality of nodes in the wireless telecommunications network, accessing sets of binned data of the PM data for each node of the plurality of nodes, comparing at least one characteristic of the binned data for each node to at least one of a threshold value and the binned data for another node of the plurality of nodes, and determining whether an anomaly is present at each of the plurality of nodes based on a result of the comparison.

摘要： Interference caused by passive intermodulation (PIM) can be automatically detected at receivers in a wireless telecommunications network, and the accuracy of PIM detection can be increased by de-weighting or ignoring time slots in which non-PIM interference is detected at a target receiver.

摘要： Tropospheric ducting can cause interference to a wireless telecommunications network from a remote source that would not normally cause such interference to the network. Interference from tropospheric ducting can be determined by analyzing tropospheric ducting factors which, individually or in combination, indicate interference from tropospheric ducting. Future tropospheric ducting interference events can be predicted using forecast data and data from past events.

摘要： A system and method that utilize data from co-sited cells that transmit and receive data on frequencies that are licensed to different operators facilitate sharing cellular configuration and performance data without revealing proprietary data to competing operators. Detection of external interference is enhanced by data from different operators.
