Abstract
Apparatus (and related methods) for a power line communication network include a processor configured to receive beacons over a communication interface. The processor determines a link quality indicator (LQI) for each received beacon and ignores the beacons for at most a predetermined maximum number of beacon receptions when each LQI is below a threshold. The processor responds to a received beacon if the LQI for such received beacon exceeds the threshold or if a predetermined maximum number of beacons have been received with LQIs below the threshold.
Claims20
An apparatus for a power line communication (PLC) network, comprising:
- an interface configured to receive a PLC signal from the PLC network;
- and
- a PLC engine coupled to the interface, the PLC engine configured to:
- extract beacons from the received PLC signal;
- determine a link quality based on the beacons;
- ignore the beacons for at most a predetermined number of beacon reception when the link quality is determined to be below a threshold;
- and
- respond to one or more of the received beacons if either the link quality associated with the received beacons exceeds the threshold or the predetermined number of beacon reception have been received with the link quality determined to be below the threshold.
An apparatus for a power line communication (PLC) network, comprising:
- means for receiving beacons;
- means for determining a link quality for each received beacon;
- means for ignoring the beacons for at most a predetermined number of beacon reception when the respective link quality is below a threshold;
- and
- means for responding to one or more of the received beacons if the link quality associated with the received beacon exceeds the threshold or if the predetermined number of beacon reception is received with the link quality below the threshold.
