High Speed Transmission of Data or Video Over Visible Light Using Li-Fi

We use a number of wireless devices to access the internet in a modern world of technology. Wireless communication is used by most of these devices. Because of the lack of radio spectrum, we can't use the electromagnetic spectrum for a longer period of time. This will lead to network complexity, bandwidth shortages, and increase the risk of interferences between radio frequencies. A new technology in wireless communication called Li-Fi uses light instead of using radio waves to transmission of data and it has an assured future. Data is transferred using light-emitting diodes in the visible spectrum. When compared to Wi-fi, it offers a less delay, higher efficiency, and the ability to transfer high amounts of data. Data is secure using Li-fi because it cannot penetrate walls, so it cannot be hacked. In this paper, the aim is to design Li-fi transceivers for high-speed data and video transmission.
