Engineered Randomness Speeds 6G Signal Lock-On Precision

Think lighthouse, not laser. In a study out of Rice University, researchers show that carefully randomized radio waves can help next-generation wireless devices find each other almost instantly at terahertz frequencies, with angle estimates finer than one tenth of a degree. The promise of 6G rests on higher frequencies that carry far more data, but those same signals fade fast and need tight, line-of-sight alignment. The Rice-led team and collaborators at Los Alamos, Sandia, and Brown report a..
