Li-Fi is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi.It is wireless and uses visible light communication or infra-red and near ultraviolet (instead of radio frequency waves) spectrum, part of optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations. It is a form of visible light communication and a subset of optical wireless communications (OWC) .This OWC technology uses light from light-emitting diodes (LEDs) as a medium to deliver networked, mobile, high-speed communication in a similar manner to Wi-Fi.
