This year’s event will also highlight VIAVI Open RAN installation and testing solutions.
With more than 20 companies, VIAVI Solutions stated that it will present the innovations supporting the major changes in the telecom industry at MWC Barcelona, March 3-6, 2025. The event’s demonstrations will highlight the value of industry cooperation and the telecom ecosystem as communication networks grow more intricate and open.
To showcase its technology in action, the VIAVI Solutions will be collaborating with industry leaders from the network, device, infrastructure, system integrator, service, and academic sectors.
For network testing, MWC will partner with Calnex Solutions; for cloud-based network management, it will leverage Infosys Cobalt; and for AI-RAN, it will partner with Samsung, NVIDIA, the Singapore University of Technology and Design (SUTD), and Yonsei University.
Qualcomm Technologies, Nokia Bell Labs, King’s College London, and the A*STAR Institute for Infocomm Research (A*STAR I2R) will collaborate on 6G.
Rohde & Schwarz, KT, and the Industrial Technology Research Institute (ITRI) will be among the non-terrestrial networks (NTN) showcases.
This year’s event will also highlight VIAVI Open RAN installation and testing solutions. VIAVI’s collaborations 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 will be highlighted in the Open RAN demos.
“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.
