- The researchers have established a new registration of wireless data over 4.6 km with infrared
- The data beams allow many high -speed parallel connections without interference
- Researchers think it can fill the connectivity gaps of the 5G and 6G Futures network
Researchers at the Eindhoven University of Technology (Tu / E) have transmitted data between the Tu / E campus and the high -tech campus over a distance of 4.6 km using infrared light.
This feat occurred at an astonishing rate of 5.7 terabits per second, the equivalent of the broadcast of 1.9 million Netflix emissions in HD simultaneously, which makes it the fastest wireless data transmission ever demonstrated over this long distance in urban areas.
The record connection was established using advanced optical antennas of Aircion, a TNO spin-off based on high-tech campus. These antennas transmit data through invisible infrared beams instead of cables or radio signals. This technique, known as the Optical Communication (FSO), allows ultra-fast and interference data transmission.
Pave the way for its future applications
“We need new ways to meet the growing demand for rapid and reliable connectivity,” said Vincent Van Vliet, a doctoral researcher Tu / e involved in the project. “Infrared wireless communication combines the speed of high data known from optical fibers with the flexibility of wireless communication systems.”
The team used Reid Photonloop’s test bed to make the breakthrough. This permanent configuration allows high -speed wireless communication experiences and uses advanced technology to combine several wavelengths in a single transmission.
“Because the infrared light transmitted is very targeted, an almost unlimited number of communication links can exist side by side without interference, allowing the growth of the capacity of the wireless network on an unprecedented scale,” said Van Vliet.
Reid Photonloop’s test bed, named after the late John Reid, an engine behind the deceased project before its realization, extends between the Flux building in Tu / E and building 37 on the high -tech campus, at a distance of 4.6 km through Eindhoven.
“This installation will allow us to refine wireless communication at high speed and optimize its reliability and availability in all weather conditions,” said Chigo Okonkwo, associate professor and head of the high -capacity optical transmission laboratory of TV / E.
Aircision sees the future applications of this technology in the connection of 5G and 6G antennas where the installation of fibers is not practical.
“We redefine how the data is transmitted in the air. This record achievement proves that our technology is ready to make broadband internet accessible to millions of people faster than ever, “said Luis Oliveira, co-founder of Aircision.
The results were presented at the 2025 Communications Fiber Conference (OFC) in San Francisco.
