Visible Light Communication is data transmission using visible light by sending data through a LED light bulb that varies in intensity faster than the human eye can follow. The term Li-Fi refers to visible light communication (VLC) technology that uses light as a medium to deliver high-speed communication in a manner nearly same as Wi-Fi. The Wi-Fi is useful for general wireless coverage within buildings while Li-Fi is ideal for high density wireless data coverage in confined areas where there are no obstacles. A free, unlicensed spectrum is used by Li-Fi and is not affected by RF noise. It provides additional security because Li-Fi cannot penetrate through walls. Since visible light is present everywhere, the main idea of this paper is to create internal navigation systems for the visually impaired using Li-Fi technology
