Abstract

See full text

The present invention provides isolation between a power line local area network and another network such as a power line wide area network. In one embodiment of the present invention, a filter device is installed on the power line supplying power to a structure in which a power line local area network is present. The example filter device may comprise a controller configured to receive a control signal and to cause a switch to activate or deactivate a low pass filter for attenuating the data signals.
