The present disclosure is directed to examples of a light fixture. In one embodiment, the light fixture includes a light source to emit a light, a photo detector to detect an incoming light, a transceiver to receive incoming data and transmit data, a modulator/demodulator to modulate the light with the data and to demodulate the incoming light with the incoming data, and a processor communicatively coupled to the light source, the photo detector, the transceiver, and the modulator/demodulator, wherein the processor is to control the modulator/demodulator to modulate the light at a transmission frequency to transmit the data via the light.
