Physical 5G Network Infrastructure

4

Network Slices, or logical networks, will be used to deliver services to multiple industry verticals over the 5G infrastructure

To realize 5G we need support in all domains

•New spectrum

•New 5G radio units

•New antennas

•High capacity and low latency

•Fibre

•Time sync

•New 5G core network

•Virtualized infrastructure (Cloud Native, NFV, SDN)

•Distributed sites

Some key 5G as-a-service concepts

7

Continuous Integration, Continuous Deployment and Automated Testing.

“Testing-as-a-Service”

“Certification-as-a-Service”Interworking across operators gives the possibility to deliver services using other network infrastructures

“Security-as-a-Service” for vertical industries (e.g. application, content and user security)

Automated infrastructure security.

Distributed Data Fabric Service to extract, compute and move data across the distributed network facility

“Data Fabric-as-a-Service”

All of these Services must be Orchestrated!
