Revolutionizing Wireless Connectivity with Cross-Band Metasurfaces

EasyChair Preprint no. 10390

Abstract

Current network technology encounters difficulties in establishing seamless indoor connections, particularly in higher frequency bands such as Wi-Fi 5GHz and mmWave, which suffer from severe signal attenuation caused by inevitable occlusions. To surmount this challenge, tunable metasurfaces emerge as a promising solution by redirecting incoming waves to circumvent obstacles. However, the absence of a theoretical framework hinders the design of metasurfaces that can effectively operate across multiple frequency bands. This work attempts to provide a general method for cross-band metasurface design, extend wireless link coverage by using a new metasurface prototype called CrossFlit, which can maximize the link quality with efficient aperture usage and low cost. our proof of concept implementation is for Wi-Fi 5 GHz and mmWave bands. The empirical evaluation demonstrates that CrossFlit can enhance widely used mmWave and Wi-Fi links simultaneously.
