Advancement in Wireless Communication using Li-Fi


Li-Fi stands for Light Fidelity. This is veritably new technology and it was proposed by German physicist Harald Haas in 2011 TED (Technology, Entertainment, Design) A Global Talk on Visible Light Communication (VLC). Li-Fi makes use of light emitting diodes (LEDs) for transmission of data. This term Li-Fi refers to visible light communication (VLC) technology and uses light as medium to deliver high-speed communication in a manner analogous to Wi-Fi and complies with the IEEE standard. This new technology known as “data through illumination” which means transmission of data through LED lights which vary in intensities faster than the human eye can follow. This technology is grounded on intensity and eventuality of light emitting diode.This paper draws its attention on construction and working of Li- Fi based system and compares its performance with the being wireless network technologies
