VIAVI Unveils Groundbreaking Advances in 6G and AI Research with Introduction of 6G City-Scale Digital Twin and AI-Native Air Interface

About this update from Viavi Solutions Inc.

[{"type":"text","content":"CHANDLER, Ariz., April 4, 2024 /PRNewswire/ -- Viavi Solutions Inc. (VIAVI) (NASDAQ: VIAV) today shared milestones in 6G and AI research based on the company's 6G Forward Program. As 6G is the first AI-native generation of wireless communications, data sources such as a 6G city-scale digital twin will be vital for training other elements of the network such as the 6G AI-Native Air Interface.\n\n \n \n \n \n \n \n\n \n6G City-Scale Digital TwinIn 2022, VIAVI announced support for research at the Institute for Wireless Internet of Things and the Open6G cooperative research center at Northeastern University, as part of the VIAVI 6G Forward Program. A key aspect of the research was large-scale RF propagation channel modeling based on AI and ML technologies to develop a city-scale digital twin of a 6G network.\nThe digital twin research has expanded to include:\nUse of AI/ML to augment ray tracing for radio frequency (RF) propagation modeling to drive the digital twinConducting real-world measurement campaigns in the Northeastern Boston campus using the VIAVI Ranger rugged RF capture and playback instrumentIncorporating higher-layer KPIs in the digital twin, to more effectively model effects 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 Dr. 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 optimization solutions in the field, gathering data from actual operator networks.\"\n\"At Northeastern's Institute for the Wireless Internet of Things (WIoT), we have been using VIAVI's state-of-the-art testing and measurement equipment to model and deploy high-fidelity digital twins of real-world wireless networks on our Open RAN Digital Twinning platform, Colosseum,\" said Professor Tommaso Melodia, Director of WIoT at Northeastern University. \"This will facilitate the research, development, and experimentation of AI-driven solutions for 5G and beyond networks in a risk-free digital-twinned world with hardware in the loop.\" \n6G AI-Native Air Interface (AI-AI)The AI-Native Air Interface (AI-AI) has appeared as a shift...
