— Visible Light Communication system uses visible light sources for wireless data transmission. VLC (Visible Light Communication) is also known as Li-Fi (Light-Fidelity). Li-Fi technology, put forth by the German physicist Harald Haas. VLC transmits data through illumination i.e. by sending data through an LED light bulb that differ in intensity faster than the human eye can follow. VLC based communication is emerging as a most propitious solution for in air, underwater wireless communication systems. As an alternative system against conventional acoustic systems, VLC can achieve high data rate. With this leading edge technology, data including text, video, audio, internet traffic, etc, can be transmitted at high speeds using LED light. One can off-load some traffic from existing RF channels, and extend cellular and Wi-Fi capacities using VLC as demand for RF frequency is increasing day by day. But VLC can’t totally replace RF frequency.
