The UK 5G Testbeds and Trials Programme ● The 2016 Autumn Statement included £740m capital funding from July 2017 to 2020-21 across the Local
Full Fibre Networks and 5G Testbeds & Trials Programme
● The 5G Testbeds & Trials Programme is seeking to contribute to the development of a ‘5G ecosystem’ in the UK by supporting both technology trials and deployment pilots to stimulate the development of 5G use cases and business models and, we hope, work towards solving some of society’s biggest challenges
● The 5G Testbeds & Trials Programme intends to:
• Stimulate the UK to become a strong contributor to the 5G sector, with leadership in specific industry verticals
• Help to accelerate 5G deployment in the UK
• Foster a diverse and efficient 5G ecosystem in the UK

5GUK TEST NETWORKS
The capabilities of the 5GUK Network were successfully demonstrated at Mobile World Congress, the World’s largest exhibition for the mobile industry, in February 2018.
The networks were created and showcased in the UK in March 2018● In Bristol, at the City’s Central Square (Millennium Square)● The KCL Campus Area- Central London● On campus at the University of Surrey.
The demonstrations highlighted the achievement of several world firsts, including testing applications over their end-to-end 5G network.

Our Vision• 5G is a Networks of Networks
• Integrating heterogeneous technologies (specific focus on fibre and wireless technologies)
• Needs to be future proof (i.e. design to evolve and change and not to be replaced)-Not 6G anytime soon!
• New business opportunities meeting the requirements of large range of use cases and service providers (enabling verticals, neutral hosting)

5G Smart Tourism: Who is Involved
Smart Internet Lab
5G enabled Smart Tourism Use Cases• Mobile AR for heritage locations – (the Roman Baths, BBC, Aardman, UoB); exploring mobile immersive video
on demand over 5G in a complex world heritage location
• Network slicing for visitor safety – (Zeetta Networks, Bristol City Council Operations Centre, UoB); demonstrating how 5G network slicing aided by SDN control can enhance visitor safety through real-time managing mission critical comms infrastructure
• 5G-enabled 3D motion tracker – (Mo-Sys, UoB); demonstration of venue-specific content over the 5G network to a person that is moving along a space wearing without the need for secondary tracking sensors, and with contextual content delivered in real-time
• Streaming 4K 360 degree content to multiple users in a small space environment for synchronous play –(Mativision, UoB)
• Grand Appeal with Aardman: opportunity Link with the 2018 “Gromit Trail”
The challenge is to bring the use cases together to aggregate impact.

Create on-demand ‘network slices’ with guaranteed QoS & full control to support media applications, CCTV video analytics & Digital Signage
Dynamically re-configure the network on external triggers e.g. emergency
5G Network Slicing & Safety Use Case- March’19
5G Technologies used in Safety Use Case:• 5G Network Slicing
• Providing visitors venues with their own “network slice” to acquire & deliver dedicated content• On-demand generation of an “first responders’ slice” in case of emergency providing instant
connectivity to compliment existing networks• mmWave or fibre Backhauling• 4G/5G Small Cell and Wi-Fi seamless access connectivity

• End-to-end orchestration and interconnection platform of individually island-orchestrated SDN and NFV infrastructure resources
• End-to-end Service Orchestration mainly at 5GUKex • No resource orchestration (delegated to Island Orchestrator) –
thin layer in order to scale
• Islands provide NS and optionally VNF information (virtual entities) to 5GUKex • Rather than infrastructure resource capabilities and
configuration information
• Experimenters to combine island NSs/VNFs to build innovative network services across islands
• ETSI NFV MANO-compliant API• Support open source orchestrators (e.g., OSM, Tacker,
OpenBaton)
• Facilitates island introduction

Smart Internet Lab
• Marketplace of VNFs, NSes, infrastructures/testbeds, past trials/test information
• AI-based inter-domain orchestration
• Development of ontology models to introduce semantics about the NSe/VNF models, QoS, location, cost for NSes/VNFs, infrastructures and trial information – facilitate
automation and introduction of AI algorithms on top to enable:• Service intents: High level requests agnostic to system implementation
• User profiling and service suggestions based on user profiles
• Smart contracts: Automatic and on-demand creation, negotiation, verification and enforcement of agreements tailored to vertical requirements
5G Exchange Evolution
Smart Internet Lab
• Networks are becoming too complex (CONNECTIVITY + DATA + AI + VERTICALS…)• Disaggregation of HW and Functions (SW)- full commoditisation of HW
• Multitenancy, multi-ownership, neutral hosting…
• Advanced very large scale monitoring (for AI, ML, DL…)
• Automated and then Autonomous network management and operations
• Programmable
• Resilient
• Low delay with high reliability: <1msec (guaranteed)
• Up to 100 Gbps connectivity to the end-user
• Geolocation accuracy better than 1 cm
• Synchronisation with 10 msec
• ….
