    Light Fidelity or Li-Fi is the latest technology that will use LED bulbs as an access point to Internet, using light as the medium through which data will be carried. As such, the technology hasn't been yet released commercially.
    The term Li-Fi has been coined by Dr. Harald Haas of the University of Edinburgh, who predicted that the Li-Fi industry could become a $113 billion industry by 2022.

    So basically, whoever has access to light can access the Internet. Sounds neat.

    Plazma Inferno!, where did you get the "...who predicted that the Li-Fi industry could become a $113 billion industry by 2022" from ?
    The article that you Linked : https://en.wikipedia.org/wiki/Li-Fi#cite_note-international.to-5 , clearly states : " The Li-Fi market is projected to have a compound annual growth rate of 82% from 2013 to 2018 and to be worth over $6 billion per year by 2018.[5] "
    Possibly you could Cite a Source for your statement : " The term Li-Fi has been coined by Dr. Harald Haas of the University of Edinburgh, who predicted that the Li-Fi industry could become a $113 billion industry by 2022. "

    Also, Plazma Inferno!, could you explain the reasoning that led you to state : " So basically, whoever has access to light can access the Internet. " ?

    Literally everyone on Earth (the surface of Earth, that is!) currently "has access to light". Yet, not everyone that currently "has access to light can access the internet".

    Also, my mistake. I meant light from bulbs. It should say electricity.

    Well, again, no. If a guy in Tanzania buys an Internet light bulb and screws it in, nothing happens.

    These light bulbs have to have access to the Internet itself - through Ethernet, or satellite radio, or WWAN, or Wi-Fi. The "light link" is just the last meter of connectivity. It is not much different than a wireless access point - it just uses a different frequency.
