    What is Li-Fi?
    Li-Fi is the use of the visible light portion of the electromagnetic spectrum to transmit information at very high speeds. This is in contrast to established forms of wireless communication such as Wi-Fi which use traditional radio frequency (RF) signals to transmit data.

    In common words Li-Fi uses light waves instead of radio waves to transmit high speed data upto 100Gbps.

    Invented By- Harald Hass in 2011.
    Why Li-fi?
    Since world is transforming, there is an abrupt need of a superfast way of internet and that only can be achieved by Li-fi, delivering speeds upto 100Gbps. The fastest Wi-fi is found to be of Korea which delivers a constant speed of 100mbps. So, Li-Fi is way ahead in speeds than Wi-Fi.

    What advantages do we get in Li-Fi over Wi-Fi?
    1) Superfast Speed - delivering upto 100Gbps.
    2) Cost Effective - since Li-Fi uses LED bulbs to transmit data, getting a Li-Fi is budget friendly.
    3) Li-Fi is not dependent on Nature conditions, where it be heavy raining or storm incoming, if u have electricity, you will have Li-Fi.
    4) Security - Since light cannot pass through walls, no one can hamper your network, until the person is under the same light.

    Are there any disadvantages too?
    Yes.
    1) Since light cannot pass through walls, and cannot bend, you must stay under the influence of light in order to be connected.
    Solution- Install several LED Li-Fi connected bulbs in every room, thus staying connected wherever the light is.

    2)Electricity- Light has to stay on in order to transmit data, thus increasing energy consumption.
    Solution- Since LED uses much low electricity it wont make a hole in your pocket for electricity.

    3) How to use at Night?
    Solution- Li-Fi enabled bulbs has the option of dimming the light to that extent that the human eye wont be able to see the light, but the data will still be transmitted.

    Is there any device which we can use for testing Li-Fi?
    Not confirmed, but there are rumours that the upcoming Iphone7 can be used for Li-Fi.

    lifi sounds good but needs hell load of development, well the worst problem is it cannot travel through walls.
    Well, this tech was discussed way back in 2015 and as you suggested (LIGHT ENABLED BULBS) would be a pathetic Idea. Instead a person should go with IR (infrared) lights which would not be seen through naked eyes thus enabling us to see during night ;)

    lifi bulbs can be dimmed too, human eyes wont detect the light but still data will be transmitted, only drawback is that since intensity of the light is dimmed, the speed of data transfer will be affected too. More light intensity=More Speed and vice versa.

    Think new, be creative. That's all I am saying. Finding an alternative without losing any speed, won't that be great ?

    Sharing what's already known is good but being creative is even better ;)
