Scientists have successfully demonstrated a new communication technology that can reliably transmit information using light beams even in harsh weather conditions with strong winds and poor atmospheric conditions. Researchers from South Africa's Wits University and France's Bordeaux University collaborated to transmit data through free space using light beams up to a distance of 270 meters in the open atmosphere.
The secret behind this success is the use of a specially designed light pattern called optical skyrmions. While ordinary laser light beams tend to distort due to wind and temperature changes, this special light pattern can preserve the original data without loss. As a result, researchers were able to successfully recover information with 86% accuracy even in the worst atmospheric conditions, and achieved over 98% accuracy in normal conditions.
This achievement represents a major step forward for future free-space optical communication technology without the need for fiber optic cables. Although further research is needed to enable longer-distance transmission, this breakthrough could soon lead to the creation of ultra-fast internet and communication networks between buildings, aircraft, satellites, and ground stations in the near future.
