Return of CB (or towards the Proximal Internet)

Motivation: why/what proximal Internet

Requirements

Some multidisciplinary research questions

2


Vision of a wireless futurePervasive computing Internet of Things Smart

everything

Competition Innovation Growth : virtuous cycle !

3

Wireless certainly,

but does it require the Internet, or a

Mobile Service Provider? - A: No. Does not require, but complements

To require is bad for competition, openness, robustness

Real and Virtual Worlds

Radio

Internet

Near ------------------ Range ------------------ Far -- tech allows us to virtualize the real world

-- where the boundary is, is a design decision!

-----------------------

Virtual


Some questions this vision raises

Q: To merge the real/virtual worlds – do we need a new radio? Is something like FlashlinQ the kind of radio we need?

- A: Something like this is worth experimenting with at scale, but this is only one possible path (and maybe far from best)

Q: How closely (and where/how in architecture) should we merge real/virtual worlds?

-A: Lots of policy, user acceptance, business model issues here

Q: Assuming we need a new radio and FlashlinQ is a good place to start, what needs to happen to get the ball rolling?

- A: What we hope to investigate…

Return of CB: Proximal Radio Requirements

Features: “as easy to use, as available, as cheap as CB Radio”

-- Anyone can buy and use to communicate (point-to-point(s), link-layer) without requiring a subscription (“unlicensed”).

-- Works without an infrastructure network. But, functionality/flexibility limited

-- Not data/m2m friendly. -- Not flexible architecture for radio (business models or policy)

8


Technical Requirements for Proximal Internet

“Moving through sea of connectivity and resources, sensing what is available and communicating peer-to-peer with resources”

Discovery: what devices are proximal? “Aura-Sense” - Shared medium (air=sound, smell, light=vision) RF - Always on automatic, continuous, passive, energy

efficient - Scalable 1000s of devices ( Spectral efficiency)

Communicate: point-to-point (any-to-any) links, proximally- Range (~1km but not ~5km) “Local” ( Mobility)

- Capacity (kbps-10 Mbps but not 100Mbps+)- Secure communication Private

9


Radio flexibility & Spectrum Management

Q: Does radio need to live in licensed spectrum (as FLQ)? - aka, protected/protocol-constrained (non-technology neutral) - But, not assigned to operator as exclusive-licensed (which not

open) - how to have flexibility of unlicensed (business model) with

interference protection/availability of licensed (technical/protocol)?

Q: If we need a “Proximal Radio” Band, how to get there? - need for international harmonization (scale economics) v.

stagnation - candidate bands? Below 3GHz – TV bands?? FRS/CB?? - mobilizing policy debate: public safety? Killer app? Niche focus?

Q: Relationship to Dynamic Spectrum Access (DSA) vision? - aka, Cognitive/software defined/”waveform” agile radios - with shared spectrum, decoupling of RF/radio/service - Is Proximal Radio a new “narrow waist” for Internet?

10


End-user control, silo apps, and platform design

Proximal radio : allow end-user to learn about resources in environment and selectively communicate with them

Q: Who controls what is sensed? - aka, is this sensing or surveillance? - is giving user choice really a choice? Q: Do different domains require different defaults? - e.g., health info v. “just-in-time” coupons - if yes, who manages the virtualization? What’s the platform? - what is the “killer app” (domain) to get the ball rolling? - how do we get these radios into the hands of users?

11


Public safety v. Retail (coupons) v. Health (monitoring)Value proposition - who pays?: public good v. ad support v. bundled niche app - when/how used?: Rare v. daily; necessity of ubiquity? - $ benefit/cost margin

Value-chain structure - who adopts? consumer v. business; B2C v. B2B - regulatory/institutional?

User experience - push/pull/ambient, automated v. manual mode - experience, not search good (?) : learning - social/network, not individual (?): influencers - etc.

12


Summing up…

Proximal Internet is key to value chain growth opportunities

A new radio is needed, a new kind of CB …

Qualcomm’s FLQ puts a worthy stake in the ground

BUT lots of research questions …

-- What’s the right spectrum management model? -- Implications of new radio platform for Internet arch? -- How will pervasive computing change our lives?
