Data at a rate of two billion bits per second.

After invention of Li-Fi, scientists have been found an another method of transferring data with a speed of up to 2 GBPS using LEDs.

This research is conducted at the King Abdullah University of Science and Technology (KAUST), the researchers have found a method of transferring data using LEDs at a speed of up to 2 GBPS. A team of researchers developed a nanocrystalline material that swiftly makes white light out of blue light showing data speeds of up to 2GB per second which can change the world of Wi-Fi.

So-called visible-light communication (VLC) makes use of parts of the electromagnetic spectrum that are unregulated and is potentially more energy-efficient. VLC also offers a way to combine information transmission with illumination and display technologies — for example, using ceiling lights to provide internet connections to laptops. Many such VLC applications require light-emitting diodes (LEDs) that produce white light.

Visible light communication (VLC) is a data communications variant which uses visible light between 400 and 800 THz (780–375 nm). VLC is a subset of optical wireless communications technologies.

When illuminated by a blue laser light, the nanocrystals emitted green light while the nitride emitted red light. Together, these combined to create a warm white light. The team could transmit data at a rate of two billion bits per second.

“The rapid response is partly due to the size of the crystals,” said Bakr in a university statement. Meanwhile, Ooi said, “We believe that white light generated using semiconductor lasers will one day replace the LED white-light bulbs for energy-efficient lighting.”
