Researchers from Peking University (PKU) and the City University of Hong Kong have unveiled a groundbreaking advancement in 6G wireless communication technology, potentially revolutionizing global connectivity. Their newly developed ultra-wideband photonic-electronic integrated system addresses long-standing challenges in cross-band signal transmission, achieving wireless speeds exceeding 100 Gbps — fast enough to stream 1,000 simultaneous 8K videos.
The innovation, detailed in Nature this week, solves critical limitations of traditional electronic hardware by enabling seamless operation across frequencies from 0.5 GHz to 115 GHz. Professor Wang Xingjun of PKU likens the technology to creating a 'super-wide communication highway,' where signals can dynamically switch lanes to avoid congestion and interference.
This breakthrough comes as global tech leaders race to develop 6G infrastructure capable of supporting advanced AI applications and IoT ecosystems. The Chinese-led project demonstrates particular promise for maintaining signal reliability in complex environments, from smart cities to industrial automation systems.
While current prototypes require further miniaturization, researchers confirm plans to integrate AI algorithms for real-time environmental sensing and interference avoidance. The development marks a significant step toward meeting 6G's ambitious performance targets while potentially reshaping global standards for next-generation networks.
