ABSTRACT
Li-Fi is the short form of Light-Fidelity. The term Li-Fi was coined by a German physicist named Harald Haas during a 2011 TEDGlobal talk in Edinburgh. Li-Fi could be a wireless communication technology that has data transmission through illumination by sending data through an LED light bulb that varies its intensity faster than the human eyesight. Li-Fi could be a light communication system that’s capable of transmitting data at a betterspeed. For example: Li-Fi transmits data at higher speed over the visible radiation, ultraviolet and spectrum. This paper focuses on analysing Li-Fi based system and understanding its performance with relation to existing technology and also how Wi-Fi may be replaced by Li-Fi. Li-Fi technology is ideally for prime speed wireless communication in avery restricted region and its many benefits over Li-Filike easeof use, efficiency, high bandwidth and security. These light based systems can communicate from street lights to auto-piloted cars headlights.
