“…This paper is an extended version of the works [16][17] originally presented partly in 2018 IEEE 29 th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), Bologna, Italy, 9-12, Sep. 2018 [16] and in 2018 IEEE Globecom'18 Workshop on Cloudified Architectures for 5G and beyond Systems, Abu Dhabi, 9-13 Dec. 2018 [17]. Both conference articles [16][17] have been used as the basis of this new journal version, which differs mainly from [16][17] in terms of enhancement of background material, expansion of discussion, and inclusion of new problems and results.

In this paper, we address two major issues regarding architectural migration of radio access network (RAN). Firstly, an overview and explicit interpretation of how different enabling technologies over generations are brought up and coordinated for migration from a distributed, to a centralized, and then to a virtualized RAN for 5G and beyond cellular; and secondly, the proof-of-concept (PoC) evaluation to understand the feasibility of these enabling technologies, are addressed. In doing so, we first give an overview of major enabling technologies and discuss their impact on RAN migration. We then evaluate the PoC of major enabling technologies proposed mainly for 5G CRAN, namely functional split options, TDM-PON systems, and virtualization techniques using a mobile CORD based prototype in LTE systems with ideal fronthauls. PoC experimental results with split options 2 and 5 are presented and compared using TCP and UDP traffic. Experimentally, it is shown that the throughput improvement is significant for TCP as compared to UDP with virtualized BBUs, which are about 30%-40% and 40%-45% higher in mean throughputs respectively in downlink and uplink with split 5 than that with split 2. Finally, we point out the major experimental limitations of PoC and future research directions.

5G mobile networks will soon be available to handle all types of applications and to provide services to massive numbers of users. In this complex and dynamic network ecosystem, an end-to-end performance analysis and optimisation will be "key" features to effectively manage the diverse requirements imposed by multiple vertical industries over the same shared infrastructure. To enable such a challenging vision, the MARSAL EU-funded project [1] targets the development and evaluation of a complete framework for the management and orchestration of network resources in 5G and beyond by utilizing a converged optical-wireless network infrastructure in the access and fronthaul/midhaul segments. In this paper, we present the network architecture of the MARSAL, as well as how the experimentation scenarios are mapped to the considered architecture.

The 5G technology offers a higher complexity than earlier generations, introducing a new type of network designed to connect virtually everyone and everything together, including vehicles, smart devices, and road infrastructure, while ensuring security, coverage, and increased performance. Therefore, following all these aspects introduced by 5G technology, different reliability assessments are necessary for optimal operation. This paper presents a practical method of real-time data measurement, which aims to obtain the necessary information to thoroughly evaluate the 5G network. The used hardware setup is based on the SIM8200EA-M2 platform for connecting to different mobile terminals. Moreover, different types of measurements are illustrated, as well as the validation of various 5G network parameters. To evaluate the 5G network performance, several performance indicators resulting from data measurement were analyzed, such as 5G network coverage, signal strength and quality, signal-to-noise ratio, throughput, communication channel quality, and transmission power. The obtained results deal with different aspects of cellular communication and can be used to analyze the 5G networks performance.
