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 .
