“…The generation and transmission of a radiofrequency (RF) signal is based on optical heterodyning with an ARoF communications scheme [22,23]. Within the ONUs, two optical signals that have a spacing equal to the carrier frequency of the desired RF electrical signal (ω RF = 2πf RF ) beat inside a high-speed photodiode (PD) [24].…”

This manuscript introduces a 5G radio access network architecture concept based on ultra-dense wavelength division multiplexing (UDWDM) and incorporating an optical fronthaul network that uses a novel wireless antenna system for radio frequency transmission and reception. A ring topology is proposed where optical signals travel within the 5G UDWDM passive optical networks and millimeter waves are generated in the optical line terminals by optical heterodyning. The wireless transmission of the millimeter waves is conducted by an innovative phased array fed reflector antenna approach for mobile communications that grants high antenna gain due to highly focused radiation characteristics, as well as multiplexing gain by multiple beam generation. Furthermore, beam steering is provided by a radio frequency analog beamformer network.Finally, implementation options synthesizing the total system are discussed.

“…This is achieved both in the optical and wireless domain. A fiber optic network is deployed underground, connecting all the important network nodes of the city and establishing connectivity with high bandwidth that enables 5G [8]. Households are connected to the network either through fiber to the home (FTTH) or through lamp posts in the city that provide high-capacity wireless broadband access [22].…”

“…SDM also allows both digital radio-over-fibre (D-RoF) and analog radio-over-fiber (A-RoF) signal transmissions [28], [29] to coexist in the same network. Finally, an SDM-based RAN system can be seamlessly combined with passive optical networks (PONs) [30], [31] and consequently offer a unique solution for a selfcontained fiber infrastructure that can be reconfigured by software-defined networking (SDN), network function virtualization (NFV) [32], adaptive beamforming techniques, and massive MIMO [35]. This future proof fronthaul infrastructure will push the radio frequency (RF) spectrum towards the mmWave range, which results in the latter already playing a key role in 5G network trial setups, especially for vertical industries that require the 5G KPIs to be fulfilled [36].…”

The next wave of innovation will certainly generate numerous new opportunities for emerging technology solutions based on networking services and applications with stringent key performance indicators (KPIs) such as ultra-low 1 ms latency, a 1000 fold bandwidth increase, 99.99 % reliability and availability, which are immensely above those supported by current mobile networks. A new architecture of mobile networking called cloud radio access network (C-RAN) has been introduced over the last few years not only to supporting these indicators, but also to increasing scalability, manageability, and flexibility of mobile systems. In this context, this paper addresses the principal technology enablers and their features for C-RAN fronthaul architectures of the 5 th generation (5G) mobile networks, namely space-division multiplexing (SDM), massive multiple-input multiple-output (MIMO) signaling, analog radio-over-fiver (A-RoF), and millimeter wave (mmWave) frequency technology. These technologies pave the way towards a truly viable and efficient fronthaul infrastructure for 5G mobile communications with connectivity for thousands of users and strict latency control. In this fashion, we perceive a network infrastructure scenario with seamless starting and ending interfaces by exploiting space diversity in both radio frequency and optical domains with efficient integrated photonics technology-all combined with adaptive softwaredefined network programming, so as to satisfy the 5G KPIs. Furthermore, we address the most relevant features of these technologies as a potential guideline for potential fronthaul infrastructure deployment of next generation mobile networks.
