6G City-Scale Digital Twin

According to Viavi, the cornerstone of this research initiative lies in the creation of a city-scale digital twin for 6G networks. Leveraging AI and machine learning (ML) technologies, Viavi says it is collaborating with Northeastern University’s Institute for Wireless Internet of Things and the Open6G cooperative research center. The focus is on large-scale radio frequency (RF) propagation channel modeling based on AI and ML technologies to develop a city-scale digital twin of a 6G network.

Key highlights of the digital twin research include the integration of AI/ML to enhance RF propagation modeling, real-world measurement campaigns conducted using Viavi Ranger rugged RF capture and playback instruments, and the incorporation of higher-layer key performance indicators (KPIs) to accurately model the impact of network conditions on application performance.

“Our research collaboration with Northeastern University has led to breakthroughs in the use of AI/ML for radio propagation modeling,” said Ian Wong, CTO Office, Viavi. “We believe this research is critical in enabling large-scale network digital twins, which Viavi is well poised to deliver given our leading network emulation solutions in the lab and network monitoring and optimisation solutions in the field, gathering data from actual operator networks.”
