Abstract

An LED light and communication system is in communication with a broadband over power line communications system. The LED light and communication system includes at least one optical transceiver light fixture. The optical transceiver light fixture includes a plurality of light emitting diodes, at least one photodetector, and a processor. A facility control unit is in communication with the light emitting diode light fixtures and a control server. The facility control unit is constructed and arranged to control the operation of the optical transceiver light fixtures.
