Light Fidelity (Li-Fi)
Light Fidelity (Li-Fi) is a bidirectional , high-speed and fully networked wireless communication technology similar to Wi-Fi . The term was coined by Harald Haas [1] and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication ( Wi-Fi or cellular networks ), or even a replacement in contexts of data broadcasting . It is wire and uv visible-light communication or infrared and near- ultraviolet instead of radio-frequency spectrum, part of optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations .
