      abstract = {A person can access the whole world at one go by using various forms of communication technologies. This paper focuses on exploring this new communication technology and give relative study on Li-Fi. In Li-Fi, from the electromagnetic (EM) frequency spectrum the visible light portion is used for information interchange which is analogous to conventional forms of wireless communication such as Bluetooth and Wireless- Fidelity (Wi-Fi), in which data or information is transmitted over the wireless medium using radio frequency (RF) signals. By modulating the intensity of light sources like LED is used as a transmitter and a photosensitive detector like Photodiodes (PD) is used for demodulation of the light signals to convert back into electrical form as a receiver. The intensity of light sources is modulated in such a way that which is unnoticeable to the human eyes. There is a crucial need of Li-Fi technology, to overcome the problem faced by the conventional wireless communication system. In this paper wide overview of need of Li-Fi, applications of Li-Fi, design challenges for Li-Fi, future scope and recent development in Li-Fi are provided. Keywords: Li ? Fi, VLC, Photodiodes.},
