Detailed Table of Contents:

Technology (1h)

Definition: What is 5G (IMT-2020)?
- For the first time: Evolution rather than Revolution
- Beamforming centric
- Deployment possible on mmWave Bands
- First steps of 5G: step 1. NSA step 2. SA
- With SA: Fully virtualized core network
Migration from 4G to 5G
- Step 1: Non-Stand-Alone (NSA) with Option 3(x)
- Step 2: Stand-Alone with Option 2
- NSA <=> SA: Which Features are supported?
Key Technical Features of 5G
- The Cloudified 5G Core Network (5GC)
- mMIMO & Beamforming: Key Enablers of 5G
- Flexible Subcarrier Spacing
  - DSS

Services and Evolution (0.75h)

List of 5G Service Enablers
- Higher Throughput (what a surprise :-))
- But watch out: 5G is not faster just because it is (4+1)G!
- Focus on lower latency (target: < 1 ms e2e)
- Beyond Cellular: 5G also contains FWA, Industry, IoT Car-2-X
- Virtualization paves the way to entirely new service areas
Cartoon: 5G around the World
Network Slicing
