Li-Fi (Light Fidelity) is the latest high speed and fully networked wireless communication technology.Original founder of Li-Fi is Professor Harald Hass from the University of Edinburgh in the UK, he is also a Co-Founder of pureLiFi, a company that has taken a lead in bringing this ground breaking-research to market.
Some of amazing Fact about this technology are as follows:
0. Very High Speed
In real-world office and industrial environments a speed of 1 Gbit/s has been achieved but Researchers have reached a data rate of over 224 Gbit/s in a laboratory environment, at this speed you can download 18 feature-length movies in single second.
1. No limitations on capacity
This technology uses visible light or infra-red and near ultraviolet spectrum, it does not uses Radio wave frequency which can cause a potential spectrum crisis because Wi-Fi is close to full capacity. Li-Fi has almost no limitations on capacity.
2. Use of LEDs bulbs as a data transmitter
Lifi will transmit data with the help of LED light bulbs by turning them ON and OFF at a very high rate, too quickly to be noticed by a human eye.At night time bulbs can be dimmed to below human visibility while still emitting enough light to carry data.
3. Can be used in Aircraft Cabins
Li-Fi can be used in electromagnetic sensitive areas such Aircraft Cabins, Hospitals and Nuclear power plants.
4. Direct line of sight isn't necessary

4. Direct line of sight isn't necessary
For Li-Fi to transmit signals, light reflected off walls can achieve a speed of 70 Mbit/s.
5. More Privacy and Security
Light waves can not pass through walls which makes it a short range network, though making it more secure from hacking, relative to Wi-Fi.
In short Li-Fi is expected to be Ten times cheaper than Wi-Fi. But Short Range, Low Reliability and high installation costs are the potential downsides.
