Presently internet has become a major demand; communities are in search of Wi-Fi hot spots. Light Fidelity was invented by Professor Harald Hass of university of Edinburgh. Li-Fi is a latest technology in present day communication system which makes the use of LEDs, Light Emitting Diodes that helps in the transmission of data much faster and flexible than the data that can be transmitted through Wi-Fi. It is basically a technology of visible light communication system which utilizes light emitting diodes as a medium of high speed communication in similar manner as Wi-Fi. Orthogonal Frequency Division Multiplexing (OFDM) based light fidelity (Li-Fi) scheme provides the opportunity of high speed data transmission along with room illumination.
