Abstract
A method for detecting noise location information in a power line distribution system is disclosed. In one embodiment, the method includes the steps of receiving link quality data for a first power line communication link between a first and second power line communications device, determining an asymmetry in the link quality data of the link, and determining location information for the noise source based on the location of the first power line communications device or the location of the second power line communications device.

A method of determining location information for a noise source in a power line communication system, comprising:
- receiving link quality data for a first power line communication link between a first and second power line communications device,
- wherein the link quality data includes upstream link quality data and downstream link quality data;
- determining an asymmetry in the upstream link quality data and the downstream link quality of said link;
- and
- determining location information for the noise source based on the location of the first power line communications device or the location of the second power line communications device.
A method of determining location information for a noise source in a power line communication system, comprising:
- receiving link quality data for at least one power line communication link between a plurality of power line communications devices;
- determining that at least one of said power line communications devices communicating over said at least one power line communication link has degraded reception performance and not degraded transmission performance;
- and
- determining location information for said at least one power line communications devices.
A method of determining location information for a noise source in a power line communication system, comprising:
- receiving link quality data for a plurality of power line communication links;
- wherein the link quality data includes data of an upstream link quality and a downstream link quality for each of the plurality of power line communication links;
- determining an asymmetry in the upstream and downstream link quality of at least one of said communication links between a first communication device and a second communication device;
- and
- determining that said first communication device communicating over said at least one link has a degraded reception performance and not a degraded transmission performance and that said second communication device communicating over said at least one link does not have a degraded reception performance.
A method of determining location information for a noise source in a power line communication system, comprising:
- receiving link quality data for a plurality of power line communication links, wherein said link quality data includes upstream link quality data and downstream link quality data;
- determining a ratio of the upstream link quality data to the downstream link quality data for each of said plurality of links;
- determining that said ratio of one of said links is not within acceptable parameters;
- and
- identifying a communication device communicating over said one link that has degraded reception performance and not degraded transmission performance.
A method of determining location information for a noise source in a power line communication system, comprising:
- receiving link quality data for a plurality of power line communication links, wherein at least some of said links communicate over the same power line;
- and
- processing said link quality data to identify a communication device that has degraded reception performance and not degraded transmission performance.
