Requirements for 5G fronthaul

2016 18th International Conference on Transparent Optical Networks (ICTON), 2016
This paper first overviews possible evolved NodeB (eNB) functional splits. Then it illustrates which requirements the Radio Access Network (RAN) shall satisfy to effectively transport 5G protocol data units (PDUs) as a function of the considered functional split.

Things you should know about fronthaul

2014 The European Conference on Optical Communication (ECOC), 2014
This paper provides a review of the new fronthaul network segment that appears in centralized radio access network (C-RAN) architecture. C-RAN drivers are presented under an operational, economic, and radio point of view. The different fronthaul interfaces are briefly described as they have to be taken into account to build a fronthaul transport ...

Coaxial Networks for 5G Fronthaul

2018 IEEE 23rd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 2018
In 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 ...

Joint Design of Fronthaul and Access Links for C-RAN With Wireless Fronthauling

IEEE Signal Processing Letters, 2016
This letter studies a joint design of fronthaul and radio access links for a cloud radio access network (C-RAN) with wireless fronthauling, where a baseband unit (BBU) controls a number of remote radio heads (RRHs) via wireless fronthaul links to communicate with user equipments.

PWM fronthauling in reflective PON

2016 European Conference on Networks and Communications (EuCNC), 2016
Pulse width modulation (PWM) has recently been proposed for analog optical fronthauling in centralized radio access networks (CRANs) to avoid the bandwidth expansion of digital fronthauling (e.g., common public radio interface protocol, CPRI). At the transmitter, the radio-signal is mapped onto the duration of an on/off keyed optical signal, while at ...

Rethink fronthaul for soft RAN

IEEE Communications Magazine, 2015
In this article we discuss the design of a new fronthaul interface for future 5G networks. The major shortcomings of current fronthaul solutions are first analyzed, and then a new fronthaul interface called next-generation fronthaul interface (NGFI) is proposed.

Next Generation Mobile Fronthaul Architectures

Optical Fiber Communication Conference, 2015
The evolution to ever higher radio bandwidths and the massive introduction of new services and technologies in 5G networks, along with their challenging requirements in the time and frequency domain will warrant revisiting the present CPRI fronthaul approach.

Optical solutions for fronthaul application (invited)

2015 14th International Conference on Optical Communications and Networks (ICOCN), 2015
Fronthaul using CPRI between BBU and RRU equipments is carried by bare fiber currently. As BBUs are more and more centralized as a pool, tremendous amount of connections may exhaust the dark fiber resource. Various optical solutions are proposed to carry CPRI.

Diversity coded 5G fronthaul wireless networks

2017 Wireless Telecommunications Symposium (WTS), 2017
In 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

Jitter impact on mobile fronthaul links

Optical Fiber Communication Conference, 2014
An innovative setup for thorough jitter characterization in fronthaul links is introduced. Tests have been carried out on an operating LTE fronthaul link measuring jitter impact on BER, EVM and frequency deviation.
