Li-Fi : The Next Generation High Speed Wireless Network

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
 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.
