Abstract
Access devices may receive signals over a network and calculate a frequency spectrum of the received signals. An analyzer system may collect the frequency spectrum data from multiple access devices, and based on the collected data, detect, identify, and locate sources of anomalies in a communication network.
Claims22
A method comprising:
- determining, by a computing device, an assigned frequency range associated with one or more access devices;
- receiving, by the computing device and from the one or more access devices, frequency spectrum data;
- determining, a signal characteristic of the frequency spectrum data for frequencies outside the assigned frequency range;
- comparing, by the computing device, the signal characteristic of the frequency spectrum data for frequencies outside the assigned frequency range, to a plurality of pre-characterized signal characteristics;
- and
- determining, by the computing device and based on the comparing, a signal anomaly.

A method comprising:
- determining, by a computing device, and for signals outside an assigned frequency range for communication channels in a network, a plurality of frequency characteristics;
- comparing, by the computing device, the plurality of frequency characteristics to a plurality of pre-characterized fault types;
- determining, by the computing device and based on the comparing, that a fault exists;
- and
- locating, by the computing device, and based on the plurality of frequency characteristics, the fault in the network.
2 more elements
A method comprising:
- collecting, by a computing device, a first set of frequency spectrum data for frequencies outside an assigned frequency range corresponding to a plurality of access devices in a network;
- collecting, by the computing device, a second set of frequency spectrum data for frequencies outside the assigned frequency range;
- determining, by the computing device, a frequency characteristic value based on the first set of frequency spectrum data and the second set of frequency spectrum data;
- comparing, by the computing device, the frequency characteristic value to a threshold value;
- and
- determining, based on the comparing, a signal fault associated with the network.
