According to Wikipedia: Li-Fi (ˈlaɪfaɪ; short for light fidelity) is wireless communication technology, which utilizes light to transmit data and position between devices.
In technical terms, Li-Fi is a light communication system (hence based on photonics) that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of visible light.
