Abstract: The fifth generation of mobile networks is emerging as a primary enabler of modern factory automation applications that ensure timely and accurate data exchange between network components. To map the service level agreement to the network attributes, regression techniques are used to develop a success model for each slice. To improve radio access network performance models, interference coordination techniques for switched beam systems have been suggested. The prediction success rate increases when more recent data is used, according to a study by regression analysis.

Cell phone network design must be drastically improved in order to satisfy these demands. However, FSO standalone is insufficient in tumultuous weather conditions. In addition, it is highly dependent on weather conditions; the FSO's results in bad weather conditions such as fog and snow have markedly decreased; these factors contribute to FSO's performance. This paper reviews the current projects in the same field of study, as well as the hybrid FSO/Radio frequency communication protocol, by naming each method used for each model in order to ensure optimal results in terms of data rate and bit Error Rate in 5G networks.

Current 4G - the fourth-generation wireless communications, available in many countries, is an improvement over the previous 3 generation wireless technologies. The most common issues of the current 4G system are increasing the proliferation of smart devices, the creation of new multimedia applications, and the increasing demand for high data rates. As a solution, the wireless system designers have started investigating on the fifth-generation wireless systems as a solution. This 5G will be the paradigm shift that could result in ultra-high data rate, low latency, an increase in the base station capacity, and improved service quality. This paper is a recap of the changes as a result of the evolution of existing cellular networks toward 5G. It was a comprehensive review of 5G, the benefits of 5G, and challenges that were not present. We will discuss the architecture changes in U2013: The radio access network, air interfaces, smart antennas, cloud RAN, and HetNet will be discussed.

The latency issue is minimized by the Cloud Radio Access Network, which has reduced the latency problem. For the edge devices, there is a need to maintain a trust level in the C-RAN node by monitoring the rates of those devices that are allowed to share information among other devices. The SDN controller is turned into a macro-cell that performs the functions of a cluster head. The edge devices are automatically authenticates by assigning a unique identifier that is shared by the cluster head with all C-RAN nodes connected to it.

As the new generation of cellular mobile communication technologies, the fifth-generation mobile communications technology is designed to create a network-based society. The 5G technology has higher security demands than previous ones, and secondary authentication is a critical device to ensure the privacy of 5G.

We report in this paper very recently on the latency characterization of a novel bidirectional visible light communication device for vehicular applications, which may be useful in automated transportation system safety applications, such as the assisted and automated braking of cars and motorbikes in critical situations. We performed a comprehensive statistical review of the observed error distribution in the communication process, determining the most likely statistical estimates of expected latency based on the observed packet error rate.

This next-generation 5G wireless standard represents the evolving face of connectivity by enabling increased automation by continuous improvement of several key performance indicators, including latency, reliability, connection density, and energy savings. While providing high-speed and low-latency services to deploy energy-efficient 5G networks with reduced carbon footprint, operators must innovate and implement innovative technologies and solutions to minimize network power consumption and minimize network emissions consumption. The simulation results demonstrate a comparative analysis between the conventional time-series forecasting methods and the new ML model that uses learned parameters. During various network load scenarios against other data-driven and statistical learning models, we feature simulations using our ECO6G model for a given dataset and show that the intended ECO6G model is accurate within $ 4. 3 million over 100,000 BSs over five years, compared to three other models that would raise OPEX costs from $ 370 million to $1. 87 billion.

Theoretic and experimental research of a wideband circularly polarized rectangular dielectric resonator antenna fed by a single feeding device has been investigated both experimentally and experimentally. The purpose of the investigation is to determine if adding a parasitic strip to the flat surface metallic feed would have an effect on various far- and near-field antenna properties. The antenna-B's result was good as compared to antenna-A, but it needed to expand the data even more, so a parasitic patch was introduced next to the Yagi-Uda antenna on the rectangular DRA at an optimized location to further enhance the results. These results reveal that parasite patches in addition to providing CP are also responsible for the return loss up by a factor of almost three times when compared to those obtained with the Yagi-Uda-shape feed alone. The proposed antenna geometry prototype was both constructed and measured.

One of the most prominent access networks in the forthcoming beyond-5G era is Wired-wireless convergence, with one of the best examples being the radio-over-fiber technology that moves broadband radio data from/to/the edge cloud to/from the antenna sites in a scalable manner. In recent years, digital signal processing has been able to play an increasingly significant role in RoF system/processing, thanks to the advancements of field-programmable gate arrays, application specific integrated circuits, and high-speed data converters. This paper aims to provide comprehensive review of three main DSP-enhanced RoF methods, namely, DSP-based intermediate-frequency over fiber, analog-to-digital compression RoF, and delta-sigma RoF.
