It's a new technology it may be available in future. It is introduced by Mr. Harald Haas a German scientist professor at Edingburg University. In this technology we use light as wireless communication device for more information see it in TED Global talk by mr. Harald haas.

    • Li-Fi Technology
    • What Is Li-Fi?  LI-FI is transmission of data through illumination, sending data through a LED light bulb that varies in intensity faster than human eye can follow -German physicist, DR. Harald Haas
    • Genesis Of Li-Fi Harald Haas, a professor at the University of Edinburgh who began his research in the field in 2004, gave a debut demonstration of what he called a Li-Fi prototype at the TED Global conference in Edinburgh on 12th July 2011. He used a table lamp with an LED bulb to transmit a video of blooming flowers that was then projected onto a screen behind him. During the event he periodically blocked the light from lamp to prove that the lamp was indeed the source of incoming data. At TEDGlobal, Has demonstrated a data rate of transmission of around 10Mbps. Two months later he achieved 123Mbps.
    • Present Scenario 1.4 Million 5 Billion
    • Present Scenario Radio Spectrum is congested but the demand for wireless data double each year .Every thing, it seems want to use wireless data but the capacity is drying up. So what can carry this excess demand in the future. Drawbacks - Capacity, Availability, Security & Efficiency.
    • Why Only Vlc  Gama rays cant be used as they could be dangerous.  X-rays have similar health issues.  Ultraviolet light is good for place without people, but other wise dangerous for the human body.  Infrared, due to eye safety regulation, can only be used with low power.
    • Bandwidth comparison
    • How Li-Fi Works ? • If the led is on, you transmit a digital 1, if its off you transmit a 0.
    • Working process
    • Difference Between The Technologies
    • Advantages Capacity Availability Efficiency High Security Easy To Use Fast Data Transfer Harmlessness Low-cost
    • Where we use in real world Aero planes Remote operated vehicles in sea Petro chemical plants Traffic control
    • Concussion The possibilities are numerous and can be explored further. If this technology can be put into practical use, every bulb can be used something like a Wi-Fi hotspot to transmit wireless data and we will proceed toward the cleaner, greener, safer and brighter future.
