Achievable Rate: ASK

[La14a]L. Landau, G. Fettweis, Information Rates employing 1-bit Quantization and Oversampling at the Receiver, SPAWC

• Significant benefit fromoversampling in terms ofachievable rate

• Significant loss of information,when considering only symbolbased detection.

Open Challenges not Addressed by 5G (1)

True network architecture for distributed/hierarchical• Security, Privacy: e2e• AAA (authentication, authorization, accounting)• Storage, Computing, Control (MEC and more)• Learning• Resilience

New PHY reaching towards 100Gb/s to 1Tb/s• New modulation (OFDM “dead” for these rates?!)• Frequencies: 100GHz• Massive MIMO 2.0

• Machine learning (antenna coupling, SON, ICIC, PA,…)• Beam acquisition & tracking for 1000 antennas and more

Secure IoT Platform

Open Challenges not Addressed by 5G (2)

Tactile Internet 2.0• True e2e 1ms latency• True network slicing 2.0: addressing plenty of “niche” markets!

Mobile Industry 4.0, Mobile Farming 4.0, Mobile Building 4.0,…

Resilience• Availability, Reliability, Recoverability – within which intervals!

Premises• Wireless Premises Networks (WPN)• Cognitive & automated

Connecting the planet: • ER cells with 100km range• Satcom?
