US 12,597,894 B1 · Power saving in HFC networks by selectively reducing spectrum utilization and bias of a power amplifier

Abstract

Selective adjustment of power amplifier bias and spectrum utilization in a broadband network. A CCAP core determines that a set of DOCSIS channels presently operational in the broadband network should be adjusted, either by consulting a schedule of peak-usage or by measuring of a current capacity utilization of the DOCSIS channels presently operational in the broadband network. When the CCAP core determines that the set of DOCSIS channels should be reduced, the CCAP core causes a subset of the DOCSIS channels to turn off at a plurality of power amplifiers throughout the broadband network. When the CCAP core determines that a new operational channel should be added to the set of DOCSIS channels presently operational, the CCAP core causes the new operational channel to turn on at the plurality of power amplifiers throughout the broadband network.
