Millimeter wave for 5G mobile fronthaul and backhaul [PDF]
2017 European Conference on Networks and Communications (EuCNC), 2017 The paper aims to provide a high-level view of 5G fronthaul and backhaul wireless transport over millimeter wave (mmWave). In particular, an overview of data rate and latency requirements for three emerging fronthaul interfaces (functional split options) in addition to the backhaul will be given first.

Secure Open Fronthaul Interface for 5G Networks
Proceedings of the 16th International Conference on Availability, Reliability and Security, 2021 The open fronthaul interface is a standard protocol for a link between the radio units and the distributed unit in RAN, enabling different vendors interoperable. We study the security requirements of the open fronthaul interface for 5G networks. The O-RAN management plane (M-plane) mandates an end-to-end security using SSHv2, whereas the O-RAN control ...

A Converged Evolved Ethernet Fronthaul for the 5G Era [PDF]
IEEE Journal on Selected Areas in Communications, 2018 We assess the performance of two distinct functional splits based on latency/latency variation and mapping efficiency, both individually and in unison. By considering hardware-offloading possibilities for a low-layer split (especially a pre-resource mapper split) using an Option-6 software-based LTE split as an example, we show how data rate, Ethernet ...
