Researchers from the University of Edinburgh have found that LED lights can be used to simultaneously transmit digital data and generate light at the same time. The findings can help eliminate the hurdles of using Light Fidelity or LiFi, which can help meet the growing demand for quality and reliable wireless communications.

 

LED products are now widely being used in many parts of the world. They are used not just in lighting but also in TV and other displays. They have been proven effective in transmitting data to and from mobiles, tablets, sensors and other devices. However, there were questions surrounding their ability to do so without affecting their core capabilities or “green” benefits.

 

Popoola explains: "Our ever more connected world will need more bandwidth than the overcrowded Radio Frequency part of the spectrum can provide,"

 

"Plugging a key knowledge gap, our results are very encouraging for the future of light-based communications that could help realise the full economic and social potential of a wireless future," he said.

 

"It's vital that LED manufacturers know what impact the incorporation of data transmission capabilities would have on their products. Our research shows that there's no dark side to using LED lights to supplement WiFi," he added.
