Challenges and Opportunities in Wireless Fronthaul
IEEE Access, 2023 To date the evolution from traditional distributed radio access networks (D-RAN) towards fronthaul oriented centralized (C-RAN) architectures has imposed significant challenges for the underlying transport network.

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 ...

Optical Fronthaul Options for Meeting 5G Requirements [PDF]
2018 20th International Conference on Transparent Optical Networks (ICTON), 2018 New functional splits for the 5G Radio Access Network have been identified so that fronthaul will no longer need to transport sampled time-domain waveforms. However, the different functional split points place differing demands on the fronthaul transport, while also posing different constraints to 5G techniques, such as massive MIMO. According to these
