Time-Sensitive Networking for 5G Fronthaul Networks
ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020In 5G radio access networks, meeting the performance requirements of the fronthaul network is quite challenging. Recent standardization and research activities are focusing on exploiting the IEEE Time Sensitive Networking (TSN) technology for fronthaul networks.

Secure Open Fronthaul Interface for 5G Networks
Proceedings of the 16th International Conference on Availability, Reliability and Security, 2021The 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 ...

Delay-Aware Uplink Fronthaul Allocation in Cloud Radio Access Networks
IEEE Transactions on Wireless Communications, 2017 In cloud radio access networks (C-RANs), the baseband units and radio units of base stations are separated, which requires high-capacity fronthaul links connecting both parts.

Coaxial Networks for 5G Fronthaul
2018 IEEE 23rd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 2018In this paper, we present an investigation about the potential of coaxial networks for 5G fronthaul. The study is motivated since some countries have a big coaxial infrastructure that could potentially be used for 5G applications. In this context, we propose here a fronthaul scheme with analog radio over coaxial cables and evaluate the maximum number ...

Optical Access Network Solutions for 5G Fronthaul
2018 20th International Conference on Transparent Optical Networks (ICTON), 2018This paper first highlights the capacity and latency requirements of the 5G mobile fronthaul and the fronthaul architecture detailing also the motivations for these requirements. The it overviews the optical access network solutions that could be used for the fronthaul and for which functional split they are deemed more appropriate.

Diversity coded 5G fronthaul wireless networks
2017 Wireless Telecommunications Symposium (WTS), 2017In this paper we study the application of Diversity Coding to enable near-instantaneous recovery from link failures in 5G wireless Cloud Radio Access Network (C-RAN) networks. We focus on networks where remote radio heads in a C-RAN are connected to the baseband unit in two hierarchical tiers with optical and wireless fronthaul links. In order to avoid

Design of C-RAN fronthaul for LTE networks
2018 21st Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN), 2018C-RAN is a mobile network architecture that enables the share of network resources in a centralised data centre, being cost- effective to the operators. This work consists of a study on the impact of C-RAN in an operator's network, addressing models for the latency and the capacity needed per data centre. The costs associated with the implementation of

MmWave Fronthaul-to-Backhaul Interference in 5G NR Networks
2021 IEEE 32nd Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2021Fixed point-to-point microwave links (P-P links) are widely used for vital backhaul connections in cellular networks. One frequency range allocated to P-P links by the International Telecommunications Union ranges from 24.25GHz to 29.5GHz. The same frequency range was also allocated to mobile services, with bands dedicated to 5G new radio (NR ...
