“…A detailed study of existing approaches to the optimal configurations of B5G networks and our experience in researching the optimal principles for designing analog fronthaul networks with the distribution of RF signals in the MMW band [16][17][18][19][20][21] suggest that for an NG-RAN, the optimal approach would be to use A-RoF as an architectural concept and MWP as a technological concept for designing an RU containing both optoelectronic and microwave-electronic (MWE) elements. However, the developer of new MWE devices including MWP units is facing a problem of choosing an appropriate computer platform for their modeling and design.…”

Specialties of an analog fronthaul based on Radio-over-Fiber architecture and key principles of exploiting microwave photonics technology when designing a millimeter-wave Radio Unit (RU) are reviewed and discussed. To clarify, in this paper we perform a comparative simulation for a specific example of developing an obligatory RU's node as a reference oscillator with an output radio frequency (RF) of more than 100 GHz, which is typically implemented by means of a circuit that includes a relatively low-frequency RF oscillator followed by a high-order frequency multiplier. Following the principles and approaches outlined, we propose and describe two alternative schemes for implementing a frequency multiplier from 4.25 to 102 GHz using microwave-electronics or microwave-photonics approach. Further, using Cadence AWRDE software with an additional introduction of the previously proposed models of optoelectronic devices, their main characteristics are considered. To ensure the practical orientation of the model experiments, the parameters of each of the models used are selected based on the specifications of commercially available discrete components.

“…An important element of a RoF-based mobile communication network (see Figure 3) is a remote station, through which an interactive fiber-wireless interface is implemented. Recently, we have proposed and previously investigated advanced design concept of cost-and power-efficient base station for emerging FiWi networks, in which for a multifrequency conversion of a RF carrier, a MWP-assisted optical frequency comb generator (OFCG) based on an optical recirculation loop (ORL) technique using two SC-SSB optical modulators was developed [19]. Leveraging the application of this OFCG for a realistic case, the simulation results by the same computer tool imitating multiwavelength optical frequency comb generation and transmission of quadrature amplitude-modulated RF signals through OFCG-based FWI of a FiWi-architected RS are discussed.…”

“…Nevertheless, transmission in IF band (see Figure 20(b)) provides versatility, as there is a simple possibility of RF conversion at a RS, both in the LR and in the HR (see Figure 1). For the effective implementation of it, we have proposed and described two RS schemes [14,19] capable of frequency converting both LR and HR.…”

For today, much attention in the upcoming 5G New Radio (NR) mobile networks is paid to radically expanding the available spectral bands up to millimeter wavelengths (MMW). Following this tendency, currently, the local telecommunication commissions of various countries are proposing and harmonizing the plans of frequency allocation in MMW band, which will be reviewed this year at the World Radio Conference (WRC-2019). Another milestone of great importance is the development of access networks. Here, well-known radio-over-fiber (RoF) technology is considered as the most promising approach, which is implemented based on fiber-wireless (FiWi) architecture. Elaborating the direction, in this chapter we review the worldwide progress of RoF-architected 5G NR access networks and highlight our last simulation results on design and optimization of millimeterphotonic-based FiWi interface. All schemes are modeled using VPIphotonics Design Suite software tool. In the result of simulation experiments, optimal design principles of optical distribution network (ODN), fiber-wireless interface (FWI), and fiber-wireless fronthaul network (FWFN) as a whole have been proposed, described, and validated.
