Lifi: The Dawn of Visible Light Communication



In the “new world” your average neon sign, store front lighting or lamp post won’t just be there to illuminate. They will peddle digital information as well as offer high speed access to the Internet. This is the dawn of the “Lifi Age” and it is all being made possible by Visible Light Communications System.

 It is interesting to note that information transmission via visible light spectrum actually predates that over radio waves. Alexander bell in 1880 actually demonstrated the transmission of speech over modulated sunlight using what he called the Photophone. So far today, visible light communication has already achieved 500Mbits/s and this can only get better.The Visible Light Communications Consortium initiated in 2004, has a lot of role to play in the coming years to facilitate the growth of this promising alternative in data and information dissemination.
