Scope and Misconceptions in Li-Fi Technology

  • prakash chalumuri



  • Everyone Already know Wi-Fi..
    So now get ready there's LI-FI....
    Which is 100times faster than Wi-Fi And interesting fact is that, IT RUNS ON LIGHT RAYS FROM BULBS..!!
    A new technology called Li-Fi (Light Fidelity) promises connections up to 100 times faster than Wi-Fi.The term Li-Fi was first coined by Prof Harald Haas from Edinburgh University, who demonstrated the technology at a Ted (Technology, Entertainment and Design) conference in 2011. His talk, which has now been watched nearly two million times, showed an LED lamp streaming video. Prof Haas described a future when billions of light bulbs could become wireless hotspots. In Li-Fi method the data will be deliver by using the visible spectrum rather than radio waves. Li-Fi can deliver internet access 100 times faster than traditional Wi-Fi.In this Li-Fi method is the use of specialized LED driver chips. These can dim and brighten LEDs encoding data much like a fast form of Morse code. The entire process happens so fast that it is completely imperceptible to humans.

    Advantages of Li-Fi over Wi-Fi
    1. Even then, there is a more important question. Why do we need an alternative means of connecting to the Internet when Wi-Fi works so well? Wi-Fi is indeed a great success, says Mr. Haas, so much so that the radio spectrum is getting overcrowded. We have deployed so many wireless access points that they interfere with each other and slow down the actual data rates. We need other pipes, fatter pipes, and light is a big pipe for wireless connectivity.
    2. Security benefits. He also maintains that there are security benefits. Light-generated Internet connections do  not travel through walls, so cannot be intercepted like a Wi-Fi signal. The professor looks  forward to a future where the much-hyped Internet of things becomes a reality; where there  is wireless connectivity everywhere; where your fridge talks to your toaster. This provides  the means to achieve that.
    People's misconception about Li-Fi working. 
    People would be forgiven for thinking that staying online with Li-Fi would need the lights left on. Haas’s Li-Fi system is so sensitive that he’s demonstrated it working with LED bulbs dimmed to such low levels that they appear turned off.
    “Currently so many companies designed a smart lighting solution for an industrial environment where the data communication is done through light. They are also doing a pilot project with a private client where we are setting up a Li-Fi network to access the Internet in their office space.”However, Velmenni was not the only company interested in bringing Li-Fi to the real world. Other names, such as Oledcomm and pureLiFi by the creator of technology Harald Haas, are also working to commercialize the technology. As Li-Fi is based on light, it cannot go through walls and would have a more limited range than Wi-Fi – which also means greater security.
