Demo: Creating Large-Scale Digital Twins for the Wireless Spectrum Through a Communication Link

Digital Twins (DTs) have become predominant for wireless spectrum emulation thanks to their realistic virtual mod-e~ing to test and optimize wireless network performance, enabling efficient spectrum management. In this work, we propose and demonstrate a bidirectional, near-real-time communication link between real-world wireless spectrum scenarios and DT replicas by utilizing the MQTT protocol. Results show that our link can achieve data transfer times with an average latency of 14 ms, which is suitable for real-time communication, allowing for our DT to be within the required latency threshold for applications such as voice communication, video streaming, and Internet of Thin2:8 (loT) control.
