South Korean scientists from Pyonhan University of Science and Technology have developed a method for broadband data transmission via visible light. The study was published in the scientific journal magazine Advanced Materials (AdMa).
According to experts, the technology they developed, called Li-Fi, can exceed the speed of modern Wi-Fi networks by more than 100 times. It eliminates the need for additional devices by using existing lighting.
One obstacle to the development of Li-Fi remained due to the overlap of electromagnetic waves of visible light of the same length. Engineers solved the problem by combining red, blue and green organic LEDs in lamps that mimic conventional lighting with a minimal interference zone.
The white light the team created showed a significantly lower transmission error rate than traditional light sources.
“We see this technology as a potentially useful tool for a variety of industries, serving as a next-generation wireless communications solution using traditional lighting systems,” said research leader Professor De Sunchun.
