Li-Fi Technology

Hey guys its my first post on my blog.Hope you will enjoy and get an idea about the technology I am going to talk about.
I am going to talk about Li-Fi technology, I think most of you already know about this but for those who don't know here it is.

Li-Fi Technology
                                                         Li-Fi means 'light fidelity'.It is a high-speed and fully networked wireless communication technology similar to Wi-Fi and is a form of visible light communication.
It is wire and uv visible-light communication or infrared and near ultraviolet instead of radio-frequency spectrum, part of optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations.

Harald Haas, coined the term "Li-Fi" at his TED Global Talk where he introduced the idea of "Wireless data from every light.He is the co-founder of pure li-fi.

This technology uses light from light-emitting diodes (LEDs) as a medium to deliver networked, mobile, high-speed communication in a similar manner to wi-fi The Li-Fi market is projected to have a growth rate of 82% per year from 2013 to 2018 and to be worth over $6 billion per year by 2018.

Visible-light communication (VLC) works by switching the current to the LEDs off and on at a very high rate, too quick to be noticed by the human eye. Although Li-Fi LEDs would have to be kept on to transmit data, they could be dimmed to below human visibility while still emitting enough light to carry data. The light waves cannot penetrate walls which makes a much shorter range, though more secure from hacking, relative to Wi-Fi. Direct line of sight is not necessary for Li-Fi to transmit a signal; light reflected off the walls can achieve 70 mbps.,which is almost 100 times that of wi-fi.

Hope you guys got an idea about Li-Fi technology.
