US 11,539,398 B1 · Variable PLC attenuator and amplifier

Abstract

A system for controlling a level of communication signals broadcast onto an associated power line communication (PLC) network by an associated transmitting device includes an input circuit, an adjustable amplifier circuit, and an output circuit. The input circuit receives a first communication signal having a first signal level from the associated transmitting device. The adjustable amplifier circuit applies a selectable gain to the first communication signal based on one or more of a monitored condition of the associated vehicle and/or a monitored condition of the associated PLC network to generate a level-adjusted communication signal having a second signal level different than the first signal level of the first communication signal. The output circuit receives the level-adjusted communication signal and broadcasts the level-adjusted communication signal onto the associated PLC network.
