In this paper, a hierarchical, distributedintelligence 5G architecture is described, offering low latency, security, and open access as features intrinsic to its design. SDN and NFV principles are employed to create a networking solution applicable to a large number of high-specification 5G use case scenarios.

From the infrastructure perspective safety, security, maintenance and crime prevention must be enhanced in line with reduced journey times even on international services. At present, the gross information capacity of intra-train guided media at 100s Mbit/s is already inadequate ($< \mathbf{200}$ Kbit/s per user) even as the roll-out of 5G technologies continues apace. This paper presents a new approach to providing higher data rates ($\approx \mathbf{100}$ Mbit/s per user) with rail-approved assemblies of media, such as twisted-pair copper cables and enhanced connectors. We present experimental throughput results on realworld railway rolling stock showing that standard Cat 5e and higher specification twisted-pair copper cable assemblies offer 40 Gbit/s data capacity between present-day train carriages.

Such an ultra-high speed 5G network can be utilised in intelligent transport system (ITS) applications, and we describe a public transport bus-based use case that takes advantage of the CHARISMA capabilities.

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.

In this paper, we present the key drivers and requirements towards a hierarchical, distributed-intelligence 5G architecture, supporting low latency, security, and open access as features intrinsic to its design. We also investigate the business perspective of the proposed 5G solution and the changes that can be foreseen for the telecom ecosystem.
