The LED lighting fixture converts the broadcast channel signal into a light signal. The smart communicator receives the light signal from the LED lighting fixture and decodes the light signal into a broadcast signal. As a result, the user can selectively receive a broadcast signal of a desired channel using a smart communicator via a nearby LED lighting fixture.
