A Review Paper on Light-Fidelity (Li-Fi)

Li-Fi that is light fidelity is one of the future technologies in wireless communication sector. It is a bidirectional, with a very high speed and is a fully networked communication which is wireless technology similar to Wi-Fi. It was developed by the German Physicist Harald Hass who has come up with an idea of sending and receiving data through LED (Light Emitting Diode) light bulb that varies the intensity faster than the human eye. According to Hass, one can use this technology in mobile phones, tablets & laptops and it would be highly secured that is if you can’t see the light that you can’t access the data. It uses light instead of radio waves to transmit information. Instead of Wi-Fi Modems, LI-Fi uses transceiver which has fitted led lamps which can glow a room as well as send and receive information. It is 100 times faster than Wi-Fi reaching at a speed of 224 gigabits per second.
