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.
Claims28
An apparatus comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
- determine an assigned frequency range associated with one or more access devices;
- receive, from the one or more access devices, frequency spectrum data;
- determine a signal characteristic of the frequency spectrum data for frequencies outside the assigned frequency range;
- perform a comparison of the signal characteristic of the frequency spectrum data for frequencies outside the assigned frequency range, to a plurality of pre-characterized signal characteristics;
- and
- determine, based on the comparison, a signal anomaly.
6 more elements
A system comprising:
- an apparatus and
- an access device;
- wherein the apparatus comprises:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
- determine, an assigned frequency range associated with one or more access devices;
- receive, from the one or more access devices, frequency spectrum data;
- determine, a signal characteristic of the frequency spectrum data for frequencies outside the assigned frequency range;
- perform a comparison of the signal characteristic of the frequency spectrum data for frequencies outside the assigned frequency range, to a plurality of pre-characterized signal characteristics;
- and
- determine, based on the comparison, a signal anomaly;
- and
- wherein the access device comprises:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors of the access device, cause the access device to send at least a portion of the frequency spectrum data.

An apparatus comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
- determine, for signals outside an assigned frequency range for communication channels in a network, a plurality of frequency characteristics;
- perform a comparison of the plurality of frequency characteristics to a plurality of pre-characterized fault types;
- determine, based on the comparison, that a fault exists;
- and
- locate, based on the plurality of frequency characteristics, the fault in the network.
