Military exploring LiFi technology for secure high data rate communications for facilities, vehicles and submarines

The Li-Fi is a wireless communication system in which light is used as a carrier signal instead of traditional radio frequency as in Wi-Fi.  Li-Fi is a technology that utilizes a light emitting diode to transmit data wirelessly. LiFi works by switching LEDs on and off within nanoseconds to communicate data, which is too quick to be noticed by the human eye. At the receiving end Li-Fi uses a photodetector to receive signals and convert them into streamable content.
