Energy-saving LEDs could help meet demand for wireless communications without affecting the quality of light or the environmental benefits they deliver, new research funded by the Engineering and Physical Sciences Research Council (EPSRC) has shown.
A University of Edinburgh team has found that transmitting digital data via LEDs, known as Light Fidelity or LiFi, at the same time as using them to generate light does not make the light dimmer or change its colour, nor does it make the LED more energy-hungry.
Dr Popoola of the University of Edinburgh, who led the research, said: “Our ever more connected world will need more bandwidth than the overcrowded Radio Frequency part of the spectrum can provide. 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. 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 downside to using LED lights to supplement WiFi.”
