5G contradictions

• Multi access (including new radios)

• Higher reliability

• Lower latency

• Full coverage

• New topologies

• NFV/SDN

Thank you!

Takeaways

Signaling increase due to MANO and

extremely dynamic control plane

Rethink architecture to improve service &

support all use cases

Upcoming Trends

Simplification of core network

New business models for operators
