Our “5G” Technical Approach• 5G and B5G 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)
• New business opportunities meeting the requirements of large range of use cases and service providers
(enabling verticals, neutral hosting)

5G Network Slicing for Public Safety
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

• To allow any service to mix-and-match and use compute, storage and
network resources upon request (at atomic level and on-the-fly)
• To support high scale: on demand levels (services, users); devices (IoT,
bodynets, etc.); points and types of technologies of access
• Distributed/decentralised solution focusing at the edge where requests arrive
(access, service, etc.)
• Targeted, customised solutions tailored for local network conditions and dynamics
(temporal and space locality)
• Enable high network dynamics: variable amounts and types of traffic;
devices (IoT, etc.); on-the-fly service composition
