From sharing to dynamic spectrum to realtime MNO-aaS

Static allocations

• National MNOs

• P2P licenses

• Manual processes

• High costs / auction model

• SP-led focus

Basic Spectrum Sharing

• Local / private / neutral MNOs

• Some manual, some SAS-based (CBRS)

• Some innovators

Automated / dynamic sharing

• Spectrum market-places inc. 2ndary

• Basic APIs

• Non realtime

• Expert buyers / integrators

Full Network-aaS

• MNO design / operation from cloud

• Spectrum, RAN, core, SIM, transport

• Looks like a toolkit

• Broad channels to market

Will harmonisation be as important in future, as in the past?

Other areas to consider

◼ Device SDR

◼ Blockchain (eg for spectrum)

◼ Intra-device wireless connections

Very-short range wireless (eg on-chip)

◼ Better 3-dimensional spectrum rights, maps & tools

◼ More device-to-device comms

◼ Post-Brexit divergence on spectrum

◼ Redefining ITU’s IMT definition beyond just “services”
