<p>The Radio Access Network (RAN) architecture evolves with different generations of mobile communication technologies and forms an indispensable component of the mobile network architecture. The main component of the RAN infrastructure is the base station, which includes a Radio Frequency unit and a baseband unit. The RAN is a collection of base stations connected to the core network to provide coverage through one or more radio access technologies. The advancement towards cloudnative networks has led to centralizing the baseband processing of radio signals. There is a trade-off between the advantages of RAN centralization (energy efficiency, power cost reduction, and the cost of the fronthaul) and the complexity of carrying traffic between the data processing unit and distributed antennas. 5G networks hold high potential for adopting the centralized architecture to reduce maintenance costs while reducing deployment costs and improving resilience, reliability, and coordination. Incorporating the concept of virtualization and centralized RAN architecture enables to meet the overall requirements for both the customer and Mobile Network Operator. Functional splitting is one of the key enablers for 5G networks. It supports Centralized RAN, virtualized Radio Access Network, and the recent Open Radio Access Networks. This survey provides a comprehensive tutorial on the paradigms of the RAN architecture evolution, its key features, and implementation challenges. It provides a thorough review of the 3rd Generation Partnership Project functional splitting complemented by associated challenges and potential solutions. The survey also presents an overview of the fronthaul and its requirements and possible solutions for implementation, algorithms, and required tools whilst providinga vision of the evaluation beyond 5G second phase.</p>

“…Spain released the all-optical policy, which plans to achieve 100% all-optical coverage in 2021. South Korea began to implement the "Giga Korea (Gigabit South Korea) Strategy" in April 2012, with the goal of reaching 100% gigabit broadband coverage in 2020 [16]. At present, South Korea has achieved more than 95% gigabit coverage, and South Korea KT Company has begun to deploy 10 gigabit broadband network.…”

The rapid rise of the digital economy is aided by the new generation of information networks. Optical Fiber networks are foundation stone of cost-effective sustainable mode of communication of our society by leveraging high bandwidth, low latency, reliability, security, stability, enabling long-term economic growth through cutting-edge services and applications for industries, business and users. F5G intends to lay the groundwork for a systematic structure to the growth of fixed networks, including generational planning and pushing the technology's innovations and expansion into as many industries as feasible through Fiber-To-The-Everywhere-and-Everything. Fixed networks have become a crucial public infrastructure in the growing global digitization process, and their development level is an essential metric for evaluating a country's overall strength. This article introduces the trend for F5G networks along with recommendations for their development.

“…Recent advances in powerful digital engines have led to the reconsideration of Digital Signal Processing-assisted (DSP-assisted) analog transport schemes for high-speed fiber-wireless connectivity in centralized topologies [6]. Additionally, when combined with advanced baseband processing software for Multiple-Input Multiple-Output (MIMO) platforms and leveraging mmWave technology, analog RoF solutions demonstrate the capability to provide multigigabit Distributed Antenna System (DAS) services at the network edge [7]. In addition to the opportunities presented by centralized DSP architectures, significant attention has been directed towards the development of integrated analog RoF transceivers, offering notable cost reductions and power efficiency for ultra-dense 5G topologies [8].…”

We introduce an ML-driven optical signal processor for dispersion compensation in B5G RAN. This approach leverages a reconfigurable, energy-efficient MRR structure, effectively mitigating power fading. Our study exploits M-QAM digitally up-converted A-IFoF transmission simulation results to fiber distances up to 25km to prove the capabilities of the designed machine learning-based analog photonic processing unit. Analytical MATLAB calculations show enhanced output power, corroborated by VPI simulations demonstrating improved EVM values, including 16.9% EVM for 1GBd QPSK at 8.5GHz over 25km, meeting the 3GPP standards.
