Title:Digital Twins for Wireless Networks, Bridging Real-World Deployments and Wireless Network Emulation
Abstract:Wireless network emulators, as Digital Twins of real systems, are becoming a staple of wireless networks design and evolution. Creating an accurate digital copy of a real system is critical to study and analyze its performance, and to design and validate robust and reliable solutions in a risk-free environment before applying them to the physical world. In this talk, we will walk through the methodology and steps to enable high-fidelity large-scale emulation-based digital twins of wireless networks. We implement these steps on Colosseum, the world’s largest wireless network emulator with hardware-in-the-loop, demonstrating unprecedented accuracies with above 98% resemblance in network parameters compared to the real-world scenarios. We will then discuss a few exemplary twinning scenarios with application in network design and performance optimization. Finally, we will touch on real-time twinning capabilities, and live-link communication between the twins as an enabler of applications such as AI-driven continuous analysis, control and performance optimization of dynamic wireless networks such as those involving UAVs.
