Li-Fi much more faster than Wi-Fi

Li-Fi (light fidelity) the future generation of networking can soon replace your wifi. It was first invented in 2011 when Prof Harald Haas demonstrated that he could transmit more data than a cellular tower by flickering light from a single LED. It is a bidirectional, high speed and a networked wireless communication technology. It transmits data and information using visible light communication. 

Lighting reaches almost everywhere, so communications through it can ride along for nearly free. Flicking LED on and off at extreme high speeds can be used to write and transmit data in binary code almost like Morse code. In scientific terms it is a visible light communication or infra-red and ultraviolet (instead of a radio frequency wave) spectrum. With Li-Fi, you can associate with the web just by being inside of scope of a LED pillar, or you could possibly transmit information utilizing your auto headlights.

Li-Fi has been tested to give speeds of upto 224 gigabits per second in the lab and is now being tested in offices in Tallinn, Estonia. Velmenni an Estonian setup has developed smart LED bulbs that can implement Li-Fi tech and they are testing it in offices environment. In 2014 a Mexican company by the name Sisoft was able to transfer data at speeds of up to 10Gbps across a light spectrum emitted by LED lamps. Li-Fi signals are narrowly-focused ‘beams’ that don’t travel through walls, it makes it a whole lot more secure. 

This OWC innovation uses light from LEDs as a medium to convey data, versatile, fast correspondence in a comparative way to Wi-Fi. Li-Fi could prompt the Internet of Things, which is everything electronic being joined with the web, with the LED lights on the hardware being utilized as Li-Fi web access points. The Li-Fi business sector is anticipated to have a compound yearly development rate of 82% from 2013 to 2018 and to be worth over $6 billion every year by 2018.

Philips lighting organization has built up a VLC framework for customers at stores. They need to download an application on their cell phone and afterward their cell phone works with the LEDs in the store. The LED lights help in pinpointing where they are actually situated in the store and give them relating coupons and data in light of which passageway they are on and what they are taking a look at.

Li-Fi has the upside of being valuable in electromagnetic touchy zones, for example, in aircrafts, hospitals and nuclear power plants without bringing about electromagnetic impedance. It has been put to utilize in hospital where RF signs are a danger because of impedance issues with medical instruments, for example, blood pumps and other life supporting instruments.

Li-Fi will presumably not totally replace Wi-Fi in the coming decades, the two advancements could be utilized together to accomplish more proficient and secure networks.Our homes, workplaces, and industry structures have as of now been fitted with foundation to give Wi-Fi, and tearing the majority of this out to supplant it with Li-Fi innovation isn't especially practical.
