“…The mature WDM technology, recognized already as a cost-efficient access solution for passive optical networks (PONs) [48,49]. With the same rationale, it can be also exploited in flexible and wavelength-reconfigurable fronthaul architectures [29] in order to meet the high-capacity 100 Gb/s KPI target for hotspot use cases [5] while at the same time, allowing for a smooth migration from the multi-SMF space division multiplexing (SDM) networks to simplified and more cost-effective single-SMF deployments [49]. Similarly, driven by the recent progress in the development of multi-core fiber (MCF) SDM hardware [50], SDM fronthaul architectures based on MCF single-fiber deployments have been also proposed as a long term solution for the hotspot use case [51].…”

“…Drawing from these latest achievements, we recently proposed an analog optical fronthaul 5G architecture that relies on PIC-based transceivers (TxRxs) and reconfigurable add/drop optical multiplexers (ROADMs) to synthesize a privately owned hotspot fiber-wireless (FiWi) network for stadiums [29], evaluated in terms of network throughput and latency [30]. Preliminary physical-layer simulation results of only the downlink fronthaul link have been also reported in [31].…”

Analog fronthauling is currently promoted as a bandwidth and energy-efficient solution that can meet the requirements of the Fifth Generation (5G) vision for low latency, high data rates and energy efficiency. In this paper, we propose an analog optical fronthaul 5G architecture, fully aligned with the emerging Centralized-Radio Access Network (C-RAN) concept. The proposed architecture exploits the wavelength division multiplexing (WDM) technique and multicarrier intermediate-frequency-over-fiber (IFoF) signal generation per wavelength in order to satisfy the demanding needs of hotspot areas. Particularly, the fronthaul link employs photonic integrated circuit (PIC)-based WDM optical transmitters (Txs) at the baseband unit (BBU), while novel reconfigurable optical add-drop multiplexers (ROADMs) cascaded in an optical bus are used at the remote radio head (RRH) site, to facilitate reconfigurable wavelength switching functionalities up to 4 wavelengths. An aggregate capacity of 96 Gb/s has been reported by exploiting two WDM links carrying multi-IF band orthogonal frequency division multiplexing (OFDM) signals at a baud rate of 0.5 Gbd with sub-carrier (SC) modulation of 64-QAM. All signals exhibited error vector magnitude (EVM) values within the acceptable 3rd Generation Partnership Project (3GPP) limits of 8%. The longest reach to place the BBU away from the hotspot was also investigated, revealing acceptable EVM performance for fiber lengths up to 4.8 km.

Enabling nonorthogonal multiple access (NOMA) in device-to-device (D2D) communications under the millimeter wave (mmWave) multiple-input multiple-output (MIMO) cellular network is of critical importance for 5G wireless systems to support low latency, high reliability, and high throughput radio access. In this paper, the closed-form expressions for the outage probability and the ergodic capacity in downlink MIMO-NOMA mmWave cellular network with D2D communications are considered, which indicates that NOMA outperforms TDMA. The influencing factors of performance, such as transmission power and antenna number, are also analyzed. It is found that higher transmission power and more antennas in the base station can decrease the outage probability and enhance the ergodic capacity of NOMA.

Network Function Virtualization (NFV)-based 5G networks deliver specific services to a set of users through the creation of Service Function Chains (SFCs), which are composed of a number of Virtualized Network Functions (VNFs) interconnected via a set of virtual links (vLinks). VNFs consume computational resources of the network's servers, while vLinks utilize the communicational resources of the network. The efficient utilization of network resources remains a challenge in NFV-based networks. To this end, in this paper, we propose an analytical framework for the calculation of the Admission Ratio (AR) in NFV-based converged optical-wireless 5G networks. The proposed methodology employs a network slicing architecture in which different network slices form end-to-end logically isolated networks and each slice delivers a specific service type to the users through its SFC(s). In the proposed analytical model, we not only take into account the occupancy distribution in both computational and communicational domains of the network resources (servers and fiber links), but we also consider the SFC establishment AR by taking into account different subservice-classes belonging to different slices. The accuracy of the model is evaluated through the comparison of analytical and simulation results and was found satisfactory. Furthermore, the network dimensioning is performed by employing the proposed model for the determination of the optimal (minimum) capacity for all SFCs elements (VNFs and vLinks) in a way that users belonging to a specific slice experience a predefined value of AR as minimum. Additionally, our calculations deploy recursive formulas, which have a low computational complexity, as opposed to time-consuming simulation approaches without requiring the application of complex optimization algorithms.
