Abstract: Nowadays almost all the peoples are using internet to accomplish their task through wired or wireless network. As number of users are increases in utilizing wireless network, speed decreases. Though Wi-Fi gives us speed up to 150 mbps as per IEEE 802.11n, which is not sufficient to accommodate number of desired users. A solution to this problem is by the use of the proposed system. Li-Fi stands for the Light-Fidelity. Li-Fi is transmission of data through light by sending data through an LED bulb that varies in intensity faster than the human eye can follow and the faster data transmission speed. Li-Fi is the new technology has used to label the fast and cheap wireless communication system, which is the next optical version of Wi-Fi.
