Researchers have successfully transmitted data at 1.5 gigabits per second using far-UVC LEDs. The breakthrough set a new record for wireless optical communication at wavelengths below 235 nanometers.
Why it matters
By utilizing light wavelengths below 280 nanometers, this system avoids interference from solar radiation, which is naturally absorbed by the upper atmosphere. This advancement could enable high-speed, secure wireless data transmission in environments where traditional radio signals are problematic.
The system reached a transmission speed of 1.5 gigabits per second over a distance of 30 centimeters. The team achieved this by segmenting the LED emitting surface into small areas to reduce junction capacitance and boost current density.
The players
Ferdinand-Braun-Institut
This is a Berlin-based research center specializing in microwave technology and optoelectronics.
University of Strathclyde
This is a public research university located in Glasgow that leads significant engineering and technology projects.
University of Cambridge
This is a prestigious collegiate research university in the United Kingdom known for its world-class scientific output.
Engineering and Physical Sciences Research Council
This is the primary United Kingdom government agency responsible for funding research and training in engineering and the physical sciences.
The details
The experiment used a direct line of sight between the transmitter and receiver under ambient room lighting conditions. Scientists utilized far-UVC light, which is considered safe because it is absorbed by the outer, non-living layers of human skin.
Timeline
September 30, 2026: The research findings were formally published.
The Tech Race
This study follows the developmental objectives established by the Engineering and Physical Sciences Research Council funding programs. It marks a shift toward utilizing the far-UVC spectrum to solve the growing problem of signal congestion in traditional wireless bands.
This breakthrough could lead to the development of new, interference-free wireless networks that operate safely in populated areas. Future iterations aim to increase transmission distances, which is necessary before the technology can be deployed for consumer or industrial use.
The takeaway
This development proves that far-UVC light can serve as a viable medium for high-capacity wireless data transmission. Researchers are now shifting focus toward optimizing hardware to support longer distances and testing stability in various atmospheric environments.
