Introduction-
Li-Fi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission.
Li-Fi is designed to use LED light bulbs similar to those currently in use in many energy-conscious homes and offices.
However, Li-Fi bulbs are outfitted with a chip that modulates the light imperceptibly for optical data transmission.
Li-Fi data is transmitted by the LED bulbs and received by photoreceptors.
History-
Professor Harald Haas, from the University of Edinburgh in the UK, is widely recognised as the original founder of Li-Fi.
He coined the term Li-Fi and is Chair of Mobile Communications at the University of Edinburgh and co- founder of pure Li-Fi.
Haas promoted this technology in his 2011 TED Global talk and helped start a company to market it.
In October 2011, companies and industry groups formed the Li-Fi Consortium to promote high-speed optical wireless systems.
The first Li-Fi smartphone prototype was presented at the Consumer Electronics Show in Las Vegas from January 7–10 in 2014.
How it is different?
Li-Fi technology is based on LEDs for the transfer of data.
The transfer of the data can be with the help of all kinds of light, no matter the part of the spectrum that they belong.
That is, the light can belong to the invisible, ultraviolet or the visible part of the spectrum.
Wi-Fi vs Li-Fi
Li-Fi can be thought of as a light-based Wi-Fi. That is, it uses light instead of radio waves to transmit information.
Instead of Wi-Fi modems, Li-Fi would use transceiver-fitted LED lamps that can light a room as well as transmit and receive information.
Wi-Fi is great for general wireless coverage within building and Li Fi is ideal for high density wireless data coverage in confined area and for relieving radio interference issues.
So the two technologies can be considered complimentary.
