Abstract
One or more infrared receiver units communicate by carrier current to an infrared transmitter unit in order to extend the operational range of an infrared remote control device that normally operates an electrical or electromechanical apparatus. The receiver converts the infrared radiation pattern produced by an infrared remote control device into a signal at a suitable frequency that is injected onto the carrier current of a facility. The transmitter, located adjacent the apparatus, converts the signal on the carrier current back into the original infrared signal used to operate the apparatus.
