Abstract
A home control system as described herein uses existing electrical power lines in a home for communications. A system includes one or more analog signal sources connected to transmit analog signals using high-bandwidth frequency channels on the electrical power lines, at relatively high bandwidths. The analog signal sources receive control data using a low-bandwidth frequency channel on the same electrical power lines, at a comparatively low bandwidth. One or more analog signal receivers are connected to receive the analog signals using the high-bandwidth frequency channels, and to receive control data using the low-bandwidth frequency channel. A controller is configured to designate one or more source/receiver groups from the analog signal sources and receivers. The controller is connected to send control data to the source and receiver of each group using the low-bandwidth frequency channel. The control data instructs each group to use a different one of the high-bandwidth frequency channels.
