Li-Fi, short for Light Fidelity, was coined by Harald Haas, Professor of Mobile Communications at the University of Edinburgh.
Li-Fi is a point-to-point wireless communication which transfers information to points not connected by an electrical conductor. It can reach speeds of up to 224 gigabits per second.
Unlike Wi-Fi, which uses radio frequency mechanical oscillations, Li-Fi uses visible-light communication, infrared or ultraviolet to transmit information.
If a user device is situated in a Li-Fi hotspot, such as a Li-Fi light bulb, there may be a transition from Wi-Fi to Li-Fi in order to enhance connection.
