Light-Fidelity (Li-Fi) Technology : A Review
Li-Fi stands for Light-Fidelity, for the fast increasing gadgets and to improve more effective use of lights a new technology is developed which is calledLIFI. Li-Fi is a modern technology which is used in progression with WIFI technology. LIFI uses LED lights which helps in faster and flexible data transfer transmitted through Wi-Fi. As light is everywhere, using light as the transmission medium Li-Fi can provide wireless indoor communication. The data transfer through LIFI is in bits and is much faster than Wi-Fi. Dr. Herald Haas, the professor of mobile communications at the University of Edinburgh, UK, first time publically displayed the proof of Light Fidelity (Li-Fi), a method of Visible Light communication (VLC). Li-Fi is the transfer of data through light by taking fiber out of fiber optics and sending data through LED light. Keywords-Li-Fi, Wi-Fi, LED Lights, Wireless, VLC, Bits and Fiber optics.
