Energy-saving Light Emitting Diodes (LEDs) could replace WiFi technology for transmitting digital data, without compromising the quality of light or environmental benefits, a study has shown.
Researchers from the University of Edinburgh in the UK found that transmitting digital data via LEDs at the same time as using them to generate light does not make the light dimmer or change its colour. It also does not make LEDs more energy-hungry.
These concerns have held back the more widespread adoption of Light Fidelity, or LiFi, which uses household LEDs to enable data transfer, said Wasiu Popoola of the University of Edinburgh, who led the research.
However, the findings help eliminate key hurdles to using LEDs to help satisfy the increasing global thirst for wireless communications. Read More…
