“DZS is proud to have collaborated in the Turin OTIC lab with Mavenir and a strong complement of other O-RAN ALLIANCE members in defining the future of 4G and 5G O-RAN architectures in Europe and around the world,” said Charlie Vogt, President and CEO, DZS. “This highly successful PlugFest in Italy showcased DZS open fronthaul transport solutions and demonstrated how we, in combination with our industry partners, can enable a path forward for service providers seeking to modernize their networks with the flexibility and efficiencies of O-RAN architectures. The success of the Global O-RAN Plugfest 2021 clearly shows that O-RAN is emerging as a compelling solution for not only greenfield networks, but also for established service providers who are already pioneering large-scale 5G deployments.”

Starting in Q3 2021, the third O-RAN ALLIANCE Global Plugfest was held in 7 venues across the world including 94 participating companies – demonstrating the commercial readiness of many O-RAN implementations. Vendors participating in the Turin OTIC lab multi-vendor interoperability test network included:
