New Future Invention Light Fidelity Li-Fi

Visible Light Communication is the wireless communication technology used in LEDs for communication and illumination. Li-Fi represents the Light Fidelity. Li-Fi allows better bandwidth, efficiency, availability and security as compare to Wi-Fi. Professor Harald Haas from the University of Edinburgh has invented the wireless technology very much like to Wi-Fi that allows data to be sent at high speeds using technology uses transmitter, receiver, modulators and demodulators for communication. Visible light communication is a new broadband transmission technology that uses standard visible light LED to transmit broadband data streams. The Li-Fi technology can be used for both dispersion of high-definition video streaming likewise two-way communication covering the whole range from internet access to video conferencing. Harlad promises a theoretical speed of Li-Fi is 10 Gbps that’s meaning using this wireless technology we can download high-definition film in just 30 seconds. Li-Fi is now part of the VLC as it is implemented using LED light Bulbs. easy to access if we access in real life then it will give high speed, high security, low maintenance charge and mainly it doesn't have any side effect because it uses visible light as transmission medium.
