Almost anyone you know is using the World Wide Web to fulfil their tasks for business or for leisure activities through a wired or wireless network. After all it is 2017 – with 2018 on the horizon – who isn’t connected to the internet these days? But, have you heard of Li-Fi before?

This state of the art technology was introduced from The University of Edinburgh by Professor Harald Haas during a TED Talk in 2011. The concept of Li-Fi is a data communication on fast flickering of light which is not detected by the human eye.

You may have heard of Wi-Fi more than Li-Fi, but in fact they can be quite similar. Both of these transmit data electromagnetically. The functioning of new Li-Fi technology is just as easy:- you will have a light source at one end like an LED and a photo detector (Light Sensor) on the other end. Although, Wi-Fi uses radio waves while Li-Fi runs on visible light.   

Because Li-Fi makes use of light waves instead of radio technology to deliver data, the resulting connection delivers up to 224 gigabits per second. The speed of internet is an important issue, as well as the time taken to load a page with images or video content, and this affects everyone. All business sectors want the correct information and prefer to operate in real time.

The Li-Fi is a wireless communication system in which light is used as a carrier signal instead of traditional radio frequency as in Wi-Fi. Li-Fi is a technology that utilises a light emitting diode to transmit data wirelessly. Li-Fi uses Visible Light Communication (VLC), a format that harnesses visible light between 400 and 800 terahertz (THz).

A Li-Fi format could be compared to a, very advanced, form of Morse code, like switching a torch on and off to relay a message. However, in this case flicking an LED on and off at extreme speeds can allow binary code to be transmitted – it uses a bidirectional and the wireless mode of communication using light.

Light receivers including solar cells, efficient computational algorithms and networking potential can be deployed in an extensive range of communication scenarios and in a diversity of device platforms. Light is used for data transmission in fibre-optic cables and for point to point links. Nevertheless, Li-Fi is a special and a novel combination of technologies that permits it to be universally adopted for mobile extremely high speed internet communications.

The main advantages are Li-Fi utilization LEDs and visible light to transmit data wirelessly as a substitute for short-range radio. It does not require any special LED bulbs, however, only standard LED bulbs which are already used in houses and offices today.

In conclusion, Li-Fi system will provide a greener, safer, optimal and healthier environment for communication systems. Li-Fi has a thousand times greater swiftness than Wi-Fi. It provides extra security as visible light is unable to infiltrate through walls.

It is simply far superior and implementable in different fields that Wi-Fi and other technologies are not able to match.
