MWC Barcelona 2025: VIAVI Collaborations Showcase Importance of Ecosystem in Advancement of AI-RAN, 6G, NTN and Open Networks

MWC collaborations will include Calnex Solutions for network test, Infosys for cloud-based network management, leveraging Infosys Cobalt, and Samsung, NVIDIA, the Singapore University of Technology and Design (SUTD) and Yonsei University for AI-RAN. 

Collaborations on 6G will feature A*STAR Institute for Infocomm Research (A*STAR I²R), King's College London, Nokia Bell Labs and Qualcomm Technologies, Inc.

Showcases for non-terrestrial networks (NTN) will include Industrial Technology Research Institute (ITRI), KT and Rohde & Schwarz.

VIAVI's solutions for Open RAN implementation and testing will also be prominent at this year's event. Open RAN demonstrations will showcase VIAVI's work with CableLabs, Calnex Solutions, Capgemini, Digital Catapult, Ericsson, i14y Lab/EANTC, Mavenir, Pegatron 5G, Quanta Cloud Technology (QCT), Radisys, Rohde & Schwarz, StarHub, SUTD, Synergy Design Technology and VVDN Technologies.

"In order to monetize their investments, operators must optimize and secure increasingly complex network architectures comprising 6G, AI and the cloud. It will take a community of trusted vendors to dynamically address the resulting challenges. The ecosystems being put in place and the standards being developed will, therefore, play a key role in the technology being delivered," said Sameh Yamany, VIAVI's Chief Technology Officer.

"With over a century in network test and optimization, VIAVI is playing a leading role in modeling, developing and enabling next-generation and mission-critical networks and we are delighted to have the support of the ecosystem at MWC."
