Field Trial of AR-based Radio Signal Visualization for Better Deployment of mmWave 5G and Beyond

Millimeter-wave (mmWave) and terahertz (THz) technologies are under consideration for Beyond 5G (B5G) and 6G. However, mmWave/THz bands suffer from high propagation loss and blockage effects, making it challenging to deploy communication areas. To address these issues, we propose a digital twin platform for future wireless communication that expands communication coverage areas for mmWave bands in 5G and beyond. In this study, we construct cyberspace based on simulation results and measurement data for the mmWave environment and use augmented reality (AR) to visualize them. We also present the effectiveness of the proposed system by verifying it in an outdoor experimental field as a proof-of-concept using an actual mmWave base station.
