Viavi Solutions Inc. announced that Capgemini collaborated with the company through Capgemini Engineering in Portugal to deliver an 5G and O-RAN lab test capability, powered by VIAVI's O-RAN Lab as a Service (LaaS). The success of 5G open networks depends on both end-to-end performance and core testing. Open networks need to provide the same performance or better than traditional networks for operators to reap the benefits of reduced infrastructure costs, with the added pressure to deliver new functionality faster than ever. Compounding these challenges is the rise of many new entrants in the supply chain, as open networks depend on a diversity of radio types and manufacturers. To address the burgeoning demand for 5G and O-RAN validation, Capgemini and VIAVI have collaborated to ensure successful network integration in 5G open environments. The VIAVI portfolio of test tools enables comprehensive measurements for the entire network lifecycle, providing functional, system integration and performance testing of gNBs, core networks, core network components and O-RAN subsystems, delivering true end-user QoE visibility.
