LiFi tested and its 100 times faster than WiFi

Well, we all know WiFi. With WiFi you have the ability to connect to the internet without having to be wired to a connection. It allows computers, mobile phones, ipads, game consoles, and many other devices to communicate over a  high-frequency radio signal. Accessing WiFi is synonym to accessing internet.

What is LiFi ? How does LiFi work ?
Simply put, WiFi uses high-frequency radio signal to transfer data, LiFi transmits data using light, yes using off-the-shelf LEDs and that too 100 time faster. The technology was first discovered by Professor Harald Haas in 2011 of the University of Edinburgh. Li-Fi uses light to beam information through the air, all we need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities: illumination and wireless data transmission.

Is it the next big thing and really better than WiFi?
With speeds of 1GBps, this technology could enable a high-definition film to be downloaded in seconds. So this technology has the potential to revolutionize how we access internet, and how the internet of things would connect in future. Check out the below video explaining LiFi a bit in detail.

When would LiFi be used by masses to access internet?
Before mass adoption of Li-Fi can be realized, techniques need to be developed to retrofit current devices with the technology. It is very difficult to create a whole new infrastructure for Li-Fi so they need to integrate LiFi system with the current system.
