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 precision by approximately 10 times compared to existing technologies [1] Group 1: Technology Development - The new method acts like an "instant GPS" for 6G communication signals, addressing the challenge of quickly aligning high-frequency signals, which is crucial for ultra-high-speed data communication [1] - High-frequency bands are expected to be key for future 6G networks, catering to high-data applications such as wireless virtual reality headsets and real-time perception systems [1] Group 2: Methodology - The developed method allows for almost instantaneous connections, enabling high-precision angle estimation of signals in a very short time, facilitating low-latency wireless link establishment or recovery [1] - The research team utilized a super-thin electronic surface that scatters signals into unique patterns based on the direction and frequency of the waves, creating distinct "electromagnetic fingerprints" for each direction [2] - The receiver can determine the signal source within a few picoseconds by comparing received signals with a pre-established signal library [2]
