Li-Fi

Light Fidelity or Li-Fi is a Visible Light Communications (VLC) system running wireless communications travelling at very high speeds..As more and more people and their many devices access wireless internet, clogged airwaves  make it difficult to latch onto a reliable signal. But radio waves are just one part of the spectrum that can carry our data. What if we could use other waves to surf the internet?A new  technology uses a part of the electromagnetic spectrum that is not greatly utilized- The Visible Spectrum.The solution,called as “Data Through Illumination”—taking the fiber out of fiber optics by sending data through an LED light bulb that varies in intensity faster than the human eye can follow.D-Light, can produce data rates faster than 10 megabits per second, which is faster than average broadband connection.Hence LED lamps that can light a room as well as transmit and receive information. It is possible to encode data in the light by varying the rate at which the ...
