Abstract

Li-Fi is the term used to describe inexpensive and fast wireless communication system and is the future optical version of Wi-Fi. Light-Fidelity(Li-Fi) enable transmission of data through illumination by sending data using light emitting diode(LED) light bulb that varies in intensity faster than the human eye can follow. Li-Fi is part of visible light communication that applied to high speed wireless communication. It uses visible spectrum of light which is a part of electromagnetic spectrum, that could transfer thousands of streams of data simultaneously, in parallel at high speeds. Wi-Fi is excellent for general wireless application within a limited geographical area, while Li-Fi is most suited for high density wireless data coverage in a confined area and for mitigating radio interference problems. Li-Fi promote better bandwidth, efficiency and security than Wi- Fi. By taking advantage of low cost of LEDs and lightning elements, there are several window of opportunities to employ this medium, from public internet access through street lights to autonomous cars that can communicate through their headlights. It is envisaged that data for laptops, smartphones and tablets will be transmitted through light in a living space.
