Slide1

Current and Future Directions in Spectrum Sharing

Martin Weiss

University of Pittsburgh

Pittsburgh PA USA

mbw@pitt.eduSlide2

Overview

Current actions in the US

Underlying factors

Conclusions & research frontier

2Slide3

Overview

Recent developments in spectrum bands (covered in more detail by Doug Sicker)

TV White Spaces

CBRS in the 3.5 GHz band

5.8 GHz

Satellite C-Band downlinks

Other sharingModel city (from PCAST)Philadelphia spatial measurement projectMore generallyCSMAC process“Bi-directional” sharing

3Slide4

Underlying questions

How do we build “social capital” in the spectrum sharing ecosystem?

What is the “low hanging fruit” of the spectrum sharing ecosystem that we can focus on?

What are we building the ecosystem for?

4Slide5

What do we mean by the “spectrum sharing ecosystem”?

Constituents

Regulators

Incumbents

Entrants

Spectrum Managers/Database operators

Spectrum allocation and assignment methodsFramework for negotiating the terms of sharing

Resource governance

Nested hierarchy?

Collective action rightsEnforcement6Slide7

What is “social capital” and how do we build it?

Social capital

The foundation on which we interact with each other

Reduces “transaction costs”

Building social capital

Experience and history

Clear rights and rulesPredictable outcomes from dispute adjudicationA note on rights enforcementInvolves potentially all stakeholders

Goes beyond

usage rights

(i.e., interference) and includes

collective action rights

7Slide8

Enforcing collective action rights

Including governance mechanisms enables CPR governance

Accountability

Locally devised rules

Nested governance

Enforcement

8Slide9

What is the “Low Hanging” fruit?

What I learned from 15 years of DSA research

We (the community) were seduced by the challenging technical problem of distributed “non-cooperative” cognitive radio systems

Bypassed the “cooperative” approaches – until TV White Spaces

How does this apply?

Address the “easy” problems first

Address the “most likely to occur” problems firstAddress problems that have a greater impact on building social capital first

9Slide10

“Low hanging fruit” examples

E

nforcement infrastructure for “routine” events

Fixed sensor network (sensing as a service) for environmental sensing

Use “citizen science” framework to build data about spectrum environment

10Slide11

Purpose of the sharing infrastructure

Lessons from unlicensed services

Platform for innovative new service

11Slide12

Toward a research agenda

Numerous meetings have taken place

Research future meeting at DySPAN 2015

US National Science Foundation (NSF)

Enhance Access to Radio Spectrum (EARS) Report

(

http://www.nsf.gov/mps/ast/2015_ears_workshop_final_report.pdf) Spectrum Measurement workshop (http://www.cs.albany.edu/~mariya/nsf_smsmw/)

Wireless System Research and Development (WSRD

) workshops (

)

Perhaps others elsewhere in the world

What are the “tall poles in the tent”?
