Project Objectives

• Design a flexible backhaul/fronthaul network for serving current and future RAN deployments in a dynamic, service oriented, and cost-effective way

• Enable seamless integration of future-proof technologies in the optical and wireless (Sub-6 GHz, mm-Wave) metro/access domains, through a converged software-based control plane

• Provide a self-consistent transport network design able to operate in a RAN agnostic way. Additionally, 5G-XHaul will make interfaces available to future RAN technologies
