:: What is Li-Fi ?

Li-Fi (Light Fidelity) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi.
It is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission.

The term Li-Fi was explored by Harald Haas, who teaches at the University of Edinburgh in the UK.
He claimed to be the inventor of Li-Fi.
It is so far measured to be about 100 times faster than some Wi-Fi implementations, reaching speeds of 224 gigabits per second.
Li-Fi is an innovative idea in IT, one that aims at eventually replacing radio frequency wireless signals with those that come from light sources.
This type of technology is still being developed, and may have the potential to introduce vastly improved wireless services.

LiFi is designed to use LED light bulbs similar to those currently in use in many energy-conscious homes and offices.
However, LiFi bulbs are outfitted with a chip that modulates the light imperceptibly for optical data transmission.
LiFi data is transmitted by the LED bulbs and received by photoreceptors.

LiFi's early developmental models were capable of 150 megabits-per-second (Mbps).
Some commercial kits enabling that speed have been released.
In the lab, with stronger LEDs and different technology, researchers have enabled 10 gigabits-per-second (Gbps), which is faster than 802.11ad.

By using LiFi in all the lights in and around a building, the technology could enable greater area of coverage than a single WiFi router.
