End-to-End Demonstration of Fiber-Wireless Fronthaul Networks Using a Hybrid Multi-IF-Over-Fiber and Radio-Over-Fiber System

IEEE Photonics Journal, 2021
This paper reports an end-to-end demonstration of a fiber-wireless mobile fronthaul (MFH) network based on hybrid intermediate-frequency-over-fiber (IFoF) and radio-over-fiber (RoF) links using a 28-GHz millimeter-wave (MMW) band.

All-Optical Network Capacity for 5G Cellular Fronthaul

2019 21st International Conference on Transparent Optical Networks (ICTON), 2019
In this paper, we have investigated the use of fast wavelength switching optical transmitters and a wavelength selective space switching all-optical network for cellular fronthaul applications. System capacity is calculated by using hard-deadlines that arise from the radio requirements and the physical constraints of the optical network.

Joint Time Synchronisation and Localisation Method by TDOA Observation in 5G Networks

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This work proposes a method for joint time synchronisation and localisation problems and proposes to obtain the initial values of the alternating iteration algorithm through solving the MVIE problem. The simulations showcase the satisfying positioning accuracy and clock synchronisation accuracy of the proposed method.

Performance Analysis of Power Control Algorithms in Uplink Cell‐Free Massive MIMO Systems

Journal of Engineering, Volume 2026, Issue 1, 2026.
Cellular massive multiple input multiple output (MIMO) technology has revolutionized wireless communication by enhancing spectral efficiency (SE). However, its ability to meet the growing data rate demands of future networks beyond fifth generation (5G) is limited by challenges like intercell interference.

SDN-based management of time-sensitive networks in 5G fronthaul

, 2018
Software Defined Networking is a key element in the 5G architecture, as it allows a more flexible, dynamic network management. Cloud RAN is another enabler of 5G, due to the expected increased based station density in the fronthaul.

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

Advanced Photonics Research, Volume 6, Issue 7, July 2025.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...
