Li Fi Technology in Wireless Data Communication

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.
