新方法给通信信号装上“瞬时GPS”为6G超高速数据网络奠定技术基础

Core Insights - Researchers from Rice University, in collaboration with Los Alamos and Sandia National Laboratories, have developed a new signal control method that can determine the direction of a signal with an accuracy of 0.1 degrees, improving upon existing technologies by approximately tenfold [1][2] - This breakthrough is likened to equipping 6G communication signals with "instant GPS," addressing the challenge of quickly aligning high-frequency signals, which is crucial for ultra-high-speed data communication [1][2] Group 1 - The high-frequency bands are expected to be a key support for future 6G networks, catering to high-data applications such as wireless virtual reality headsets and real-time perception systems [1] - The developed method allows for almost instantaneous connections, enabling wireless links to be established or restored with extremely low latency, facilitating automatic identification and alignment of devices within milliseconds or even picoseconds [1][2] Group 2 - The technology functions like a "lighthouse" emitting multi-colored light, where each color's intensity varies randomly in different directions, allowing receivers to deduce their precise position relative to the transmitter [2] - The use of a super-thin electronic surface enables the scattering of signals into unique patterns based on direction and frequency, creating distinct "electromagnetic fingerprints" for rapid signal source identification [2] - This foundational breakthrough resolves the issue of rapid alignment of 6G signals, paving the way for widespread applications in wireless VR, holographic communication, and remote precision surgery, all of which require near-zero latency for massive data transmission [2]
