Network slicing as a key enabler for different products/services on the same infrastructure

5G Networks need to support flexible levels

  • f:

Mobility, Latency, Bandwidth, Coverage, Functionality , …

Situation: Diversity

  • f use cases call for

flexibility

„All in One“ Network Multiple Networks

Challenge: Limitation

  • f classic solutions

Strong capabilities for tailored solutions, guaranteed resources and fast provisioning

Solution: Multiple logical network build on one physical infrastructure

Business Application Layer Infrastructure Control Layer Physical Layer

Existing Spectrum New Spectrum

  • Evolution of existing technology

adding new RAN technology

  • LTE+ and New Air Interface

combined allows rapid switching based on radio conditions

  • New Air Interface initially applied at

new spectrum (up to millimeter waves) with super channels, massive MIMO & beam forming

  • Gradual migration of New Air

5G in a nutshell

  • 5G is being developed as a solution for a multitude of existing problems
  • 5G will cause a revolutionary evolution of our existing network(s) and services
  • 5G development should be driven by Customer Needs
  • 5G should become (new) Service Enabler
  • 5G slicing is key for a successful implementation
  • 5G system orchestration is native SDN/ NFV* structure
  • 5G’s New Air Interface will require new frequency bands
  • Massive IoT, Energy, Autonomous driving and Ultra-Mobile-Broadband are foreseen

as the first applications for 5G
