“Open RAN requires a full understanding of technical architecture and the interdependent multi-vendor ecosystem.”
Chris PearsonPresident, 5G Americas
“SLA management and seamless integration with existing networks are critical to the success of Open RAN deployments. Artificial Intelligence and Machine Learning applications will be essential tools to help manage and monetize networks with multiple spectrum bands, network slices and varied applications in this new 5G environment.”Amit Mehrotra, Nokia’s Global Head of Sales for Network Planning, Optimization and Analytics
“The Open RAN approach has benefited from global collaboration in the telecom ecosystem and presents itself as an alternative worthy of consideration for greenfield deployments or any time operators embark on network upgrades or enhancements.”Durga Satapathy, Director, Advanced Technologies & Innovation at T-Mobile
“Managing the operations and the customer satisfaction of a heterogeneous-cellular network requires a complex and labor-intensive organization with specific objectives and key success factors. As cellular network operators transition to increasingly diverse heterogeneous 5G systems, AI and machine learning are increasingly needed to not only help manage capital investment, but also to manage the increasingly complex networks”Charlie Michaelis, Associate Director of Big Data for AT&T
