Digital Twin For RIS-Aided Systems
The practical deployment of reconfigurable intelligent surfaces (RIS) faces significant challenges in accurate modeling and seamless integration. Traditional analytical approaches often rely on idealized assumptions, which limits their ability to capture the complexity of real-world environments. At CCSL, we leverage Digital Twin (DT) technology to create high-fidelity representations of practical scenarios, enabling more realistic analysis and bridging the gap between theoretical models and real-world RIS implementations.
Overview
Introduction
Beyond 5G networks are expected to deliver ultra-reliable, low-latency, and high-capacity connectivity. One of the key enabling technologies for achieving these goals is a reconfigurable intelligent surface (RIS), which is a programmable metasurface composed of many passive elements, each capable of adjusting the phase of incident signals. By intelligently controlling these elements, RIS can manipulate wireless propagation environment to enhance coverage, increase capacity, and improve energy efficiency. To accurately model the behavior of RIS within complex and dynamic environments, digital twins are used to capture realistic performance of RIS-aided systems. This work introduces digital twin framework for three RIS-aided systems in indoor environments: single RIS-aided, cascaded RISs-aided, and RIS partitioning. The proposed digital twin model is validated through experimental measurements and theoretical calculations, with performance evaluated in terms of the received signal strength indicator (RSSI).
