Abstract

An LED light and communication system includes at least one optical transceiver, the optical transceiver including a light support and a processor. The light support has a plurality of light emitting diodes and at least one photodetector attached thereto, the light emitting diodes receiving power from a power source. The processor is in communication with the light emitting diodes and the at least one photodetector, the processor capable of illuminating the light emitting diodes to simultaneously create at least one first light signal, and at least one second light signal, the first light signal being observable to the unaided eyes of an individual and the second light signal not being observable to the unaided eyes of the individual. The second light signal includes at least one data packet. The at least one data packet comprises global positioning system (GPS) location information.
