LIGHT FIDELITY: A WAY OF DATA TRANSMISSION

Li-Fi is a very efficient, simple and cheaper network that can be used for wireless data transmission. It is considered to be better than the trending technology, i.e. Wi-Fi, in terms of cost and efficiency of usage. Li-Fi complies with the IEEE standard 802.15.7. The paper focuses on explaining the concept and meaning of Li-Fi technology. In this paper we have explained the different components necessary for constructing a Li-Fi system. Its features, different applications and future uses are also discussed in brief. The use and importance of LED light in the working of Li-Fi is also described. The VLC technology (for increasing the transmission speed) used in Li-Fi has been explained briefly.
