Toward scalable passive optically powered fronthaul networks

Journal of Optical Communications and Networking
The evolution of wireless networks toward 5G and beyond has introduced challenges in designing efficient and cost-effective fronthaul networks. This paper focuses on the power-enabled optical fronthaul design (POFD) problem, which seeks to optimize the placement of optical splitters and their connections to radio units and distributed units while ...

Design of C-RAN fronthaul for LTE networks

2018 21st Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN), 2018
C-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

Reliable and resilient coordinated multi point fronthaul networks

2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON), 2018
Very fast link failure recovery and high throughput can be achieved via the synergistic combination of Diversity and Network Coding (DC-NC), an open-loop coding technique, in a wide variety of network architectures. In this paper, DC-NC is applied to enable recovering from a wireless link/node failure in the fronthaul portion of downlink Coordinated ...

Fiber-Wireless Fronthaul/Backhaul Network Architectures for 5G

2018 IEEE 23rd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 2018
5G-PHOS R &D project aims at architecting and evaluating 5G broadband networks for dense, ultra-dense and hotspot area use cases by capitalizing on existing wireless and optical technologies, while migrating from CPRI -based towards integrated Fiber-Wireless (FiWi) fronthaul/backhaul supporting mmWave mMIMO communications.

Handling Delay in 5G Ethernet Mobile Fronthaul Networks

2018 European Conference on Networks and Communications (EuCNC), 2018
In this paper we discuss how to handle delay in 5G Ethernet mobile fronthaul networks. The reasons for the delay requirements, addressing both service and protocol specific requirements, are discussed together with prime carrier needs of scalability of networks and easy migration to new network solutions.

Firefly Ultra Dense Networks with mmWave Fronthaul Links

2018 IEEE Globecom Workshops (GC Wkshps), 2018
We consider the uplink of firefly ultra dense networks which combine the promising features of ultra dense deployment and centralized processing. In these networks, a large number of radio units, also referred to as firefly nodes (FNs), are spatially distributed over an area.

Solutions for future mobile fronthaul access-network convergence

Optical Fiber Communication Conference, 2016
• Solutions for future mobile fronthaul □ In the short to mid term, how to carry CPRI/OBSAI/ORI is the key. The solutions include IQ-data compression, and fronthaul with WDM. □ In the mid to long term, a new function split is under study. It realizes a packet-based fronthaul, which allows the use of the cost-effective TDM PON technology. □ DSP-assisted

Enhanced Diversity and Network Coded 5G Wireless Fog-Based-Fronthaul Networks

2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018
The synergistic combination of Diversity and Network Coding (DC-NC) was previously introduced to provide very low end-to-end latency in recovering from a link failure and improve the throughput for a wide variety of network architectures. This paper is directed towards further improving DC-NC to be able to tolerate multiple, simultaneous link failures ...

Joint relay selection and beamforming for mmWave fronthauling network

2017 IEEE/CIC International Conference on Communications in China (ICCC), 2017
Millimeter-wave (mmWave) fronthaul for Cloud-RAN has been considered as a promising 5G technique to meet the surging demand for high data rate. However, the Non-line-of-sight (NLOS) transmission problem seriously impacts the reliability of fronthauling network, and may leads to the breakdown of network.
