China’s award-winning 6G tech turns every wall and pipe into a sensor

China’s 6G engineers have built a special metasurface system that can bounce wireless signals around like a precision mirror to fill in dead spots, while still sensing people moving about – just like a radar. The innovation earned a gold award at the International Exhibition of Inventions in Geneva in March, the online results of which were announced on June 14. The innovation is named Distributed Integrated Sensing and Communication Metasurface (DISACM). It uses intelligent reconfigurable...
