WiFi runs our life. In fact, according to a survey carried out by Direct Line by Opinium Research online, it is the number one thing that their respondents couldn’t live without. 

But no matter where you are in the world, you’ve probably experienced internet connectivity problems at one point or another.

Enter LiFi, a type of wireless connection that can be up to 100 times faster than
WiFi.
* Imagine a world where you can connect to high-speed internet by just flicking 
on your light switch.
* LiFi is a wireless optical networking technology that uses LEDs for 
data transmission. 
* In simpler terms, LiFi is considered to be a light-based WiFi that uses light 

instead of radio waves 

TO transmit information. 

* Using light to transmit data allows LiFi to deliver a couple of advantages 

such as working in areas susceptible to electromagnetic interference like hospitals 

and aircraft cabins and working across higher bandwidth while offering higher 

transmission speeds.

* The LiFi technology is currently being developed by numerous organizations 

around the world.

 

How does LiFi work?

* LiFi is a Visible Light Communications system transmitting wireless 

internet communications at very high speeds. 

* The technology makes a LED light bulb emit pulses of light that are undetectable 

to the human eye and within those emitted pulses, data can travel to and 

from receivers. 

* Then, the receivers collect information and interpret the transmitted data. 

* This is conceptually similar to decoding Morse code but at a much faster rate – 

millions of times a second.

* LiFi transmission speeds can go over 100 Gbps, 14 times faster than WiGig, 

also known as the world’s fastest WiFi.


Whereas WiFi technology effects data transfer on radio waves, LiFi takes the next revolutionary step in wireless evolution and embeds and transfers data in visible light beams, thereby allowing LiFi to take full advantage of the vastly greater light spectrum bandwidth capacity that is provided by the light spectrum.

How it works exactly

Data is captured in modulated light frequencies of a solid-sate LED light source and is then transmitted and received by LiFi-enabled devices. A photosensitive detector demodulates the light frequency signal and converts it back into an electronic data stream and – in so doing – allows for faster-than-ever, more secure, bi-directional wireless communication.
