Li-Fi - Computer Definition
A digital, wireless visible light communication (VLC) technology that uses LED lights. Unlike Wi-Fi, Li-Fi signals are not subject to electromagnetic interference and can be used in airplanes, hospitals and underwater. Invented by Professor Harald Haas, University of Edinburgh, Li-Fi requires line of sight from transmitter to receiver; however, the light pulses can be redirected from mirrors and white walls.
