    Yes, it's time to shift from Wi-Fi to Li-Fi — an alternative technology that is 100 times faster than the average speeds of Wi-Fi.



    Scientists have just field-tested the new wireless technology called Li-Fi for the first time and achieved marvelous wireless speeds that are 100 times faster than current WiFi speeds.


    What is Li-Fi Technology?



    Li-Fi is a new wireless technology that transmits high-speed data using light (i.e. Visible Light Communication or VLC) rather than radio bands.


    In short, Li-Fi is a Super-Fast alternative to Wi-Fi.

    Earlier this year, scientists achieved mind-blowing speeds of 224 gigabits per second (Gbps) in the lab using Li-Fi. It's believed that this technology has the potential to change everything about the way we use the Internet today.


    And Yes, it will.


    Test Results: Li-Fi is 100 times Faster than Wi-Fi



    An Estonian startup company called Velmenni took the technology out of the laboratories and into the real-world offices, and industrial environments in Tallinn for the first time and, believe me, it's really, really fast.

    The company was able to transmit data at 1GB per second, which is almost 100 times faster than the Wi-Fi speeds.

    Unlike Wi-Fi network signals, Li-Fi is based on light and can't penetrate through walls, which makes it more secure from external sniffing. Meanwhile, it also means there is less interference from other devices.


    Who Invented Li-Fi?



    The Li-Fi technology was originated in 2011 by German physicist Harald Haas, who outlined the idea of using light bulbs as wireless routers during a TED Talk. He demonstrated that with a flickering light from an LED, one could transmit more data than a cellular tower.





    P.S- Want more info, search on Google :p a49ffc87e321c5fb2010938d5902c801.600x.jpg

    They're gonna have to find a way to make processing power faster and more affordable now.

    Hello,

    Just one question: if the signals can't penetrate through walls, it means your computer and your Li-FI box must be in the same room, right? You can't move your computer ?

    They will be transmitting signal through special bulbs - so your lamps/light sources will be distributors. If you ask me the idea is ridiculous stupid for spaces besides offices since you will need to be in range to use this. So if you think you can go to your backyard, have bbq and still be able to use net - not really.

    Not really, but I think more that I can take my portable computer, go in my bedroom, and watch a streaming movie while the Li-Fi box is in the living room (and I don't even talk about homes with floors).

    Even in offices it would be pointless compared to existing wired connection, since they would need to all be using quad channel DDR4 ram disks to even consider needing the kind of speeds li-fi offers.

    Yeah but think about how widespread light is nowadays :p

    I'm sure there will be some workarounds once it is settled in 2-3 years when they go live.

    Yes, I have heard about that. Currently it's still in testing phase, then probably the Army would implement it and use it for a couple of years. After that.. it will be available to the general public. So don't expect to see it in your home 2 soon.
