VIAVI Unveils Groundbreaking Advances in 6G and AI Research with Introduction of 6G City-Scale Digital Twin and AI-Native Air InterfaceCHANDLER, 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. 6G City-Scale Digital Twin The digital twin research has expanded to include:
"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." "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." 6G AI-Native Air Interface (AI-AI) To enable comprehensive testing of neural receivers, VIAVI has developed and demonstrated its own receiver as part of an end-to-end test and training environment. The base station employs an AI-aided constellation design, where the modulation block is replaced with a neural network to design custom constellation for the receiver. The VIAVI in-house developed neural receiver is generalizable over various channel models and modulations, delay and doppler, signal-to-noise ratio (SNR) and other conditions, which is vital for deployment in practical systems. VIAVI used open-source and in-house libraries to implement the transceiver architecture. "VIAVI continues to explore and develop groundbreaking future generations of wireless technology, and we are at the frontier of AI-native 6G," said Dr. Stephen Wang, Managing Director, VIAVI Marconi Labs. "From neural receivers to rate-splitting multiple access for semantic networks, our 6G research helps the industry create networks that dynamically adapt to different environments and conditions. We look forward to working with research labs and network equipment manufacturers to accelerate development of these technologies." About VIAVI Media Inquiries:
