Light Fidelity (Li-Fi) - 5G visible light communication system

Picture this - You woke up in the morning and you order your coffee machine for a coffee with just a text from your phone. OR take this - Your refrigerator sends you a text that today you are out of orange. Sounds weird and out of the world, is it?? But actually the fact is at the forefront of this connectivity phenomenon popularly known as the "Internet Of Things", is an optical telecommunication technology that is taking the world by a storm. Li-Fi, is an exciting breakthrough in 5G communication system and the future of wireless internet access.

Theory : -

1)With Li-Fi, information hitches a ride along a spectrum of visible light.
2)Light-emitting diode(LED) bulbs, transmit data when they are switched on and off so rapidly in nanoseconds,that the human eye cannot see it.
3)The data is registered by special equipment, making it possible to provide wireless internet connectivity at a current experimental speed up to 10Gbps,which according to my research, is estimated to be 250 times faster than "super fast" broadband. 

Other Advantages Of Li-Fi : - 

1) Zero electromagnetic interference, allowing connectivity connectivity even in areas where Wi-Fi is not accepted - hospitals and nuclear plants among others.
2) It provides better data defense as light waves can't pass walls,making it impossible to hack any internal systems in high-security buildings.
3) As radio waves used by Wi-Fi get more congested and the demand for faster and more efficient wireless communication escalates , the future is bright for Li-Fi as a reliable, affordable and more secure solution

Research : -

1) Harold Haas from the university of Edinburgh, who first demonstrated Li-Fi to the world, evisioned turning light bulbs into super-speed broadband wireless internet systems.
2) Smartphones will soon be able to download traffic information from traffic lights or a program guide from a television.This is the tip of the iceberg.
3) In the future , shops will transmit advertisements to your phone as you pass byand bus schedule changes will be transmitted to a screen at the stop.
4) In fact, the Li-Fi industry is set to become a $6 billion industry by 2018.



How else do you think that Li-Fi will revolutionize the way we connect with man and machines?
