Abstract
A method and device for increasing the bandwidth of a drop line in a power line carrier communication system for facilitating high speed transmission of communication data. The drop line is divided into two sections, each containing both high frequency communication data components and low frequency power components. A high pass filter is provided for passing the high frequency components to a receiver device and a low pass filter is provided for passing the low frequency power components to an electrical system in a residence. The low pass filter is also used for blocking, from the drop line, high frequency noise generated by electrical appliances operating from the electrical system.
