Researchers at Eindhoven University of Technology (TU/e) have demonstrated a high-speed wireless data transmission of 5.7 Tb/s (Terabits per second) across a distance of 4.6 kilometers (2.85 miles) using invisible infrared light beams. This achievement is said to represent the highest data rate recorded for wireless communication over such a distance in an urban setting.
The high-speed connection was established between the TU/e campus in the north and the High Tech Campus (HTC) in the south of Eindhoven. Utilizing advanced optical antennas developed by Aircision, a local telecommunications equipment supplier, the system employs free-space optical (FSO) communication. This technique transmits data through focused infrared beams, offering ultra-fast, interference-free wireless communication without relying on traditional cables or radio signals.
