6G’s Evolutionary Challenges “Stretching 5G”
Reduce latency → below 5ms end-2-end (e.g. for robotics)
Increase data rate → beyond 10Gb/s (e.g. for VR)
Expand coverage → connect 4B people missed-out
Scalable HW/SW → enable cost-efficient applications (e.g. verticals)
Cleanup NFV → entangle NFV & Openstack (e.g. “lean NFV”?)
