Abstract

An LED light and communication system in communication with a broadband over power line communications system. The LED light and communication system includes at least one optical transceiver. The optical transceiver includes a light support having a plurality of light emitting diodes and at least one photodetector attached thereto, and a processor. The processor is in communication with the light emitting diodes and the at least one photodetector. The processor is constructed and arranged to generate a communication signal. The at least one optical transceiver is engaged to a clock, and the clock is in communication with the broadband over power line communications system.
