Abstract

Light Fidelity (Li-Fi) technology is a novel method of wireless communication network based on the use of visible LED lights between the violet (800 THz) and red (400 THz) to transmit data wirelessly. Li-Fi has much broader spectrum compared to conventional methods of wireless communication for data transmission which depends on radio waves. The principle of Li-Fi is based on sending data by amplitude modulation of light source in a well-defined and consistent way. The concept of Li-Fi assures to solve issues like shortage of radio-frequency bandwidth and eliminates the drawbacks of Radio communication technologies. Li-Fi technology provides better bandwidth, faster transfer speed, efficiency and security as compared with Wi-Fi. This paper focuses on working of Li-Fi, its applications, features and comparison with existing technologies like Wi-Fi etc. P.
