VARIABLE INPUT IMPEDANCE FOR POWERLINE COMMUNICATIONS

摘要

A powerline communication (PLC) device can receive a PLC signal transmitted through a powerline medium. The PLC device can compare a destination address of the PLC signal to a device address associated with the PLC device. The input impedance of the PLC device can be configured to an impedance value that is different from an impedance of the powerline medium when the destination address does not match the device address. The input impedance of the PLC device can be returned to an initial value when a PLC message included in the PLC signal is no longer received.

主权项

1. A method comprising:
determining a destination address associated with a first powerline communication (PLC) signal received at a PLC device via a powerline medium; determining whether an address of the PLC device matches the destination address; and modifying an input impedance of the PLC device based, at least in part, on an impedance of the powerline medium and whether the address of the PLC device matches the destination address.
