ANSWER: Light Fidelity
Li-Fi or Light Fidelity is a new technology going mainstream where LED will be used to access the Web and not just give light. The term Li-Fi was coined in 2011 by Professor Harald Haas of the University of Edinburgh. Li-FI is a technology which could revolutionise business models, create fresh opportunities and be a USD 113 billion industry by 2022. RF or radio frequency spectrum would not be enough for wireless data communication because visible light spectrum is much larger. Use of Light Spectrum for Li-Fi overcomes issues in traditional wireless communication such as spectrum shortage and network disruption on account of interference. Through Li-Fi, anyone who has access to light can remain online and access the Internet without losing network connections. Li-Flame described as the world’s first true Li-Fi system was displayed at Barcelona’s Mobile World Congress in March 2015.
About Li-FI
Light Fidelity is a new technology using light waves instead of radio frequency waves as a medium for carrying out data whereby improved LED bulb work as a router. Li-Fi works by connecting LED bulb to device which is in turn connected to the net. Internet data flows in through the device into the bulb and carried by light waves. At the other end, light waves carrying the net data fall on receive/USB connected to computer.
