Abstract

A method for operating a PLC system including at least one PLC modem device, in which interferences on transmission signals of the PLC system and/or on a transmission spectrum of the PLC system are detected, the interferences are caused by influences of an impedance modulating device connected to a mains used by the PLC system for communication, and, in a case such interferences are detected, frequencies on which the impedance modulating device causes interferences are selected to be notched from power line communication and/or time periods when the impedance modulating device is in a switching mode are selected to be avoided for transmitting PLC signals. A PLC modem device and a PLC system can implement the method.
