Chinese scientists have recently successfully developed an ultra-wideband optoelectronic integrated system, achieving for the first time full-band, flexibly tunable high-speed wireless communication, which is expected to provide support for smoother and more reliable 6G wireless communication in the future.
As the next generation of wireless communication networks, 6G needs to meet high-speed transmission of wireless signals across various frequency bands in diverse scenarios. However, traditional electronic hardware is only suitable for a single frequency band, and devices for different bands have different designs, structures, and materials, making it difficult to achieve cross-band or full-band operation.
To address this, a joint research team spent four years independently developing an ultra-wideband optoelectronic integrated system. This system enables high-speed transmission at any frequency point from 0.5GHz to 115GHz—a full-band compatibility capability that is internationally leading. The system also features flexible tunability; when signals are interfered with, it can dynamically switch to a secure frequency band to establish a new communication channel, improving communication reliability and spectrum utilization efficiency.
“This technology is like building an ultra-wide highway where vehicles are electronic signals and lanes are frequency bands. In the past, vehicles could only crowd into one or two lanes, but now there are many lanes to choose from. If one lane is blocked, vehicles can flexibly change lanes and continue moving, allowing faster travel without congestion.”
By integrating AI algorithms, this new system will enable more flexible and intelligent AI wireless networks. It can not only be applied in various complex scenarios, achieving real-time data transmission and precise environmental sensing simultaneously, but also automatically avoid interfering signals, making network signal transmission safer and smoother.
