In November 2025, Rice University in the U.S., in partnership with Los Alamos and Sandia National Laboratories, unveiled an innovative signal control technology. This technology can achieve directional positioning with an impressive precision of 0.1 degrees right at the instant a signal is sent out, boasting an accuracy tenfold higher than that of current technologies.

By utilizing an ultra-thin electronic surface, this technology creates a distinct electromagnetic wave "fingerprint" with a designated direction. This allows for ultra-precise alignment between devices handling 6G high-frequency signals within picoseconds. It effectively tackles the issues of connection disruptions stemming from the rapid attenuation of signals and their weak penetration capabilities in high-frequency scenarios.

The relevant research findings were published in the journal Communications Engineering. This breakthrough offers crucial technical backing for applications that demand zero-latency transmission, including wireless virtual reality (VR), holographic communication, and remote surgery. Moreover, it propels the advancement of 6G networks towards greater intelligence and reliability.
