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

An Insight into the Total Cost of Ownership of 5G Fronthauling
2018 20th International Conference on Transparent Optical Networks (ICTON), 2018This paper provides an assessment of the total cost of ownership (TCO) of a number of 5G fronthauling solutions based on digital and analog radio-over-fiber (RoF) architectures in cloud radio access network (C-RAN). We computed the capital and operational expenditures (CAPEX, OPEX) in the case of an optical fiber aggregation network based on a ring ...

5G Fronthaul Enabled by WDM Radio-over-Fiber
Frontiers in Optics / Laser Science, 2020We propose a low-cost DML-based hybrid fiber-wireless WDM radio-over-fiber transmission system for 5G fronthaul networks with resource allocation flexibility under different traffic loads and demonstrate it with a proof-of-concept experiment.

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 ...

Fronthaul in 5G Transport Networks: IEEE1914.1 Architecture and Requirements
2020 22nd International Conference on Transparent Optical Networks (ICTON), 2020The deployment of 5G New Radio (NR) implies the capability both to deliver new mobile services (eMBB, URLLC, mMTC) and to perform critical functions as massive MIMO, beamforming, carrier aggregation, CoMP and scalable centralized/virtualized radio access network (C-RAN/V-RAN).

Enhanced Fronthaul for 5G and Beyond
2022In the radio access network (RAN) infrastructure, fronthaul links territorially disperse remote units (RUs) to distributed units (DUs) in regular or open RAN. With the fifth generation (5G) rollout worldwide and the active research on technologies beyond 5G, fronthaul has become a critical part of RAN to balance throughput, delay, reliability, and ...

Processing Resource Allocation in 5G Fronthaul
2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC), 2019A dynamic simulator is, for the first time, proposed to evaluate solutions generated by a meta-heuristic based on the greedy randomized adaptive search procedure (GRASP) and variable neighborhood descent (VND) to ensure reliability in the optical fronthaul with the functional split recommended to the fifth generation (5G) cellular network architecture.

Efficient Airborne Network Clustering for 5G Backhauling and Fronthauling
2020 16th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2020Interests in the exploration and use of Unmanned Aerial Vehicles (UAVs) for service provision have risen in recent years. However, the use of UAVs to extend or solely provide Fifth Generation (5G) wireless network coverage in rural and low income areas is one application area that is yet to be extensively researched.
