LiFi –Wireless Communication using Light

LiFi (Light Fidelity)is a high-speed wireless communication technology that uses visible light (presently using LEDs) to transmit information. LiFi is a wireless technology. LiFi uses visible light communication (VLC) or infrared and near-UV spectrum waves rather than radio waves. In other words, LiFi works by using visible light, like the light that is emitted by any regular lamp or bulb. This paper draws its attention on working of LiFi based system and applications of LiFi in different area.
