A survey on Transmission of data through illumination - Li-Fi
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 12
Abstract
Li-Fi is a new wireless technology to provide the connectivity with in localized network environment. The main principle of this technology is we can transmit the data using light illumination by using light-emitting diodes where radio frequency is media in Wi-Fi and LED bulb light intensity is faster than human eye can follow. Prof Harald Haas an expert in optical wireless communications at the University of Edinburgh, he was demonstrated how an LED bulb equipped with signal processing technology could stream a high-definition video to a computer. By using this technology a one-watt LED light bulb would be enough to provide net connectivity to four computers. He coined the term "light fidelity" or li-fi and set up a private company, Pure VLC, to exploit the technology. . He envisions a future where data for laptops, smart phones, and tablets is transmitted through the light in a room. And security would be snap – if you can’t see the light, you can’t access the data.
