Abstract:
1. A method performed by a data processing apparatus, the method comprising: obtaining data specifying a baseline data rate for transmissions from a node that are received over a channel of a power line communications system, the channel being one of a plurality of available channels allocated for communications with the node; providing, to the node, data specifying a selected modulation technique; selecting an available channel for a selected one of a plurality of modulation techniques based on an assessment of data transmission efficiency of the data transmitted from the node, wherefrom the node is reconfigured to transmit over at least one of a different channel and a different modulation technique; determining a noise-tolerance threshold associated with the selected modulation technique, the noise-tolerance threshold for the modulation technique being a measure at which the modulation technique provides the baseline data rate with at least a threshold confidence; and selecting an available channel, from among the plurality of available channels, for the node in response to the step of determining, the selected channel being a channel over which the selected modulation technique can provide the baseline data rate with at least the threshold confidence.
