Fiber-Wireless Fronthaul/Backhaul Network Architectures for 5G

Abstract

5G-PHOS R &D project aims at architecting and evaluating 5G broadband networks for dense, ultra-dense and hotspot area use cases by capitalizing on existing wireless and optical technologies, while migrating from CPRI -based towards integrated Fiber-Wireless (FiWi) fronthaul/backhaul supporting mmWave mMIMO communications. This paper provides a revolutionary approach for the definition of the 5G-PHOS use cases by developing realistic usage/traffic scenarios for a real geographical area with known characteristics, taking into account specific 5G services mix. In addition, the paper presents network solutions to support the 5G-PHOS use cases.
