A handy invention

November 22, 2016 A Vision for Wireless Testbeds 7

If we built an RF equivalent . . . ?

RF illumination patterns Fading and reflections Even select by modulations Probably feasible to build / demo

November 22, 2016 A Vision for Wireless Testbeds 8

What will we see in 20 years ?

• A world drenched in RF
• Much fuller spectrum occupancy than today
• Many, many illuminators with a wide variety of radiation

patterns (lots of beams)

• Many very agile illuminators (beam steering, spectrum,

coding, distributed beam forming, etc etc)

• Many flickering, mobile illuminators

November 22, 2016 A Vision for Wireless Testbeds 9

Kind of like this, everywhere

When everything is the cloud,

Wireless is the Cloud’s Skin

Edge datacenters Regional datacenters Core datacenters

Ubiquitous high-capacity wireless “skin”

November 22, 2016 A Vision for Wireless Testbeds 12

A first step into this new world

Cloud Radio Access Networks (CRANs)

November 22, 2016 A Vision for Wireless Testbeds 13

A more radical architecture

• A fundamentally sliced (multi-tenant) architecture
• SDRs w/ multiple back ends (pub sub)
• Multifunction RF, all software-defined
• Cloud-style, not telco-style

Multi-tenant cloud Multi-tenant cloud

Sliced processing chains with SDR Sliced processing chains with SDR

A very simple case

Why not use the knowledge you have ?

I know where I’m going I know where I’m going Cloud scheduling wireless assets / handoff

November 22, 2016 A Vision for Wireless Testbeds 17

City-wide traffic orchestration?

Why should cars be autonomous ? Even more so, why should drones be ? Surely they should leverage all existing knowledge about everything in the city…..

November 22, 2016 A Vision for Wireless Testbeds 18

Can every network access point help robots navigate ?

From E911 -> wifi -> wallplug appliance ?

November 22, 2016 A Vision for Wireless Testbeds 19

Can every city get, as a service, a realtime, distributed radar system ?

Run radar slice in parallel with comms Leverage dense RF transmitters Maybe add tailored waveforms for weather, drones, etc etc (SDR…) Multistatic transmitters & receivers

November 22, 2016 A Vision for Wireless Testbeds 20

Urban transport / automobiles ?

• DARPA GXV-T
• Extreme mobility
• (Why have 4 wheels?)
• No windows
• Augmented cloud-based

reality instead

• Looking forward . . .

– Perhaps divorce “coach” from chassis, a personal “living room” with a leased-per-drive chassis ? – “Coach” as in trimodal containers, joining “buses” within city, parking bins, slide into hyperloop, etc – Chassis can service people, freight haulage, etc

November 22, 2016 A Vision for Wireless Testbeds 21

Extremely fine-grain realtime sensing ?

• Lidar on every car ?
• Projected cost: $250 / unit
• Current Velodyne stats

– 120m range, < 2cm accuracy – 64 channels (emitter/receiver pairs) – 2.2 Million points per second – About 100 Mbps data stream

• What if we harvested / pooled all those “data torrents”?

– Many looks at everything near a road (many cars, many angles) – Continuous, realtime infrastructure monitoring – Measuring weather and climate change (watch leaves) – Counting cars at walmart – Realtime RF channel models (e.g. leaves again) – Synthetic data for those windows

The best way to predict the future is to invent it
