Abstract:
1. An apparatus comprising: an input port configured to receive an alternating current (AC) waveform from a power line that is external to the apparatus; coupling circuitry coupled with the input port; power line communication (PLC) circuitry coupled with the coupling circuitry, configured to use the coupling circuitry to transmit and receive PLC signals via the power line, wherein the coupling circuitry and the PLC circuitry are electrically exposed to the AC waveform via the input port; a communication port coupled with the PLC circuitry, configured to provide PLC network access via the PLC circuitry; a filter coupled with the input port, configured to remove the PLC signals from the AC waveform and to produce a filtered AC waveform; and a power supply coupled with the filter to receive the filtered AC waveform, the power supply configured to produce a direct current (DC) waveform in accordance with a control signal; and a power supply controller coupled with the power supply, the power supply controller configured to produce the control signal, and cause the power supply to change modes during a PLC signal reception period via the control signal to reduce or eliminate interference from the power supply during the PLC signal reception period.
