You are may be familiar with the term WIFI(Wireless Fidelity) we all know this ,but have you heard about Lifi Which is 100 Times Faster than Wifi ?No.Then mark this page it'll give you detailed review of Lifi .

 LIFI(Light Fidelity) is High speed Communication technology introduced by Prof. Harald Haas at University of Edinburgh.He Promoted His Tech On Global TED talks have a look 





How LIFI Works?
LiFi uses the visible light portion of the electromagnetic spectrum to transmit information at very high speed. Where wireless communication such as Wi-Fi which use traditional radio frequency (RF) signals to transmit data. Li-Fi is wireless and uses similar 802.11 protocols; but it uses visible light communication (instead of radio frequency waves), which has much wider bandwidth.
Future OF lifi
Scientist are already experimented getting results of 224GB/sec .Yes you heard it Gb per second you can download 10 movies of 10gb in 10 seconds .Illuminating Led uses visible light between 400 and 800 terahertz (THz). It works basically just like switching a torch on and off according to a certain pattern can relay a secret message, flicking an LED on and off at extreme speeds can be used to write and transmit things in binary code.

When it will be available for Dailyuse?

Lifi is fast but it has it's limitations for now it is expected to be working fully on smartphones and other portable devices by 2022.homes, offices, and industry buildings have already been fitted with infrastructure to provide Wi-Fi, about to replace it with Li-Fi technology isn’t particularly feasible, so the idea is to fit the devices we have right now to work with Li-Fi.

 Li-Fi experts reported that Haas and his team have launched PureLiFi, a company that offers a plug-and-play application for secure wireless Internet access with a capacity of 11.5 MB per second, which is comparable to first generation Wi-Fi. And French tech company Oledcomm is in the process of installing its own Li-Fi technology in local hospitals.


"Lifi will change the whole experience of using the internet ,we hope for a better and faster future and by these technology we are taking steps for the future"
