Demonstration of a real-time E/W-band wireless transmission system over a 20-km SSMF and a 3.7-km wireless link with 24-hour continuous field testing.
The fifth-generation (5G) communication provides rapid growth in global data traffic, bringing millimeter waves into focus due to its large available bandwidth. Here we successfully demonstrate a real-time long-haul photonics-aided E/W-band wireless transmission system, achieving 12.5 Gb/s over a practical 3.7-km wireless link. A continuous 24-hour field test under fluctuating humidity, temperature, and wind speed conditions robustly validates the system's reliability and confirms its feasibility for real-world deployment. We also carried out experiments combining a 20-km standard single-mode fiber (SSMF) with the 3.7-km wireless segment, analyzing the fiber-induced performance impairments. The proposed millimeter-wave wireless communication system thus demonstrates significant potential to meet the evolving requirements of next-generation mobile networks.
