Assessment of socio-techno-economic factors affecting the market adoption and evolution of 5G networks: Evidence from the 5G-PPP CHARISMA project

5G networks are rapidly becoming the means to accommodate the complex demands of vertical sectors. The European project CHARISMA is aiming to develop a hierarchical, distributed-intelligence 5G architecture, offering low latency, security, and open access as features intrinsic to its design. Finding its place in such a complex landscape consisting of heterogeneous technologies and devices, requires the designers of the CHARISMA and other similar 5G architectures, as well as other related market actors to take into account the multiple technical, economic and social aspects that will affect the deployment and the rate of adoption of 5G networks by the general public. In this paper, a roadmapping activity identifying the key technological and socio-economic issues is performed, so as to help ensure a smooth transition from the legacy to future 5G networks. Based on the fuzzy Analytical Hierarchy Process (AHP) method, a survey of pairwise comparisons has been conducted within the CHARISMA project by 5G technology and deployment experts, with several critical aspects identified and prioritized. The conclusions drawn are expected to be a valuable tool for decision and policy makers as well as for stakeholders

Towards Mobile Data Centres: Provision of End-to-End 10 and 40 Gbit/s Ethernet Train Backbones on International Rolling Stock

The next generation of railway customer-oriented services are expected to generate a large volume of data ( ≈ 10s of TB). As a result, passengers' applications, safety, security, and Internet-on-Board (IoB) sensors challenge current Train Communication Networks. With the present Ethernet Train Backbone (ETB) specification of just 100 Mbit/s in total, railway passenger services will not support intelligent, seamlessly connected and mobile media on-board trains. In this paper, we propose a novel ETB design with experimental results demonstrating end-to-end 10 Gbit/s and 40 Gbit/s throughput results over existing conducting media on commercial railway carriages. This is equivalent to 100 Mbit/s per user on real-world railway rolling stock and shows that standard RailCat 5e cabling and new rail-approved 10 Gbit/s ETB active nodes (switches) fully support emerging trends and future-proof ETB configurations

High capacity communications at 24 GHz and 60 GHz for converged 5G networking

Next-generation 5G converged networks need to support applications requiring ultra-high speed wireless links exceeding 1 Gb/s, e.g. large file transfer and high definition video streaming, e.g. for D2D and D2I communications. Here, we describe wireless networking throughput beyond gigabit rates employing the 24 GHz (unlicensed ISM), and 60 GHz (802.11ad standard) bands. 802.11ad offers large available spectrum (>8.6 GHz) and defines protocols to enable throughput intensive applications such as wireless uncompressed video. Investigation of real-time, 24-GHz, wireless data communication in non-line-of-sight (NLoS) and multipath-rich scenarios is also presented. 24 GHz can also deliver 1 GbE in typical modern building environments while penetrating a range of commonly used construction materials. Security and latency are also important 5G issues, where mm-wave technologies are additionally expected to play an important enabling role

Ultra-High-Definition Video Transmission for Mission-Critical Communication Systems Applications: Challenges and Solutions

With the standardization of ultra-high-definition formats and their increasing adoption within the multimedia industry, it has become vital to investigate how such a resolution could impact the quality of experience with respect to mission-critical communication systems. While this standardization enables improved perceptual quality of video content, how it can be used in mission-critical communications remains a challenge, with the main challenge being processing. This chapter discusses the challenges and potential solutions for the deployment of ultra-high-definition video transmission for mission-critical applications. In addition, it examines the state-of-the-art solutions for video processing and explores potential solutions. Finally, the authors predict future research directions in this area

Security

Future 5th generation (5G) technologies are anticipated to address next generation network’s challenges and tackle the novel business requirements associated with different vertical sectors. This implies that 5G technologies will not only encompass new wired and wireless network technologies to support higher data rates, bandwidths, numbers of devices, etc., as elaborated in Chapter 2, but also need to be cohesively aligned from a technological as well as business standpoint with the different vertical sectors, for their optimized and efficient use of the network, for instance through customized network slices. Furthermore, convergence, automation and flexibility are expected to be intrinsic traits of any 5G system. The introduction of this multitude of complex new requirements and novel technologies immensely impacts the security landscape of 5G, and therefore the need to revisit its properties becomes essential
