Abstract
Now a days, wireless communications has become fundamental to our lives and we transmit a lot of data every day. The main way we transmit wireless data is by using electromagnetic waves, in particular radio waves. There is an emerging wireless communication with a promising future and which can be a complement of radio waves i.e. Li-Fi. This paper describes the importance of the Li-Fi technology and the areas where it can be advantageous. Li-Fi also called as Light Fidelity is a new technology that uses light source i.e. light emitting diodes that can be used for high speed communication. It is a better alternative as compared to Wi-Fi technology. It is a technology based on the principle of VLC technology. It is a safer, greener and cheaper technology as it does not have any radio waves or any other type of waves. This technology provides better capacity, security, and availability as compared to Wi-Fi.
