FUTURE CR DEVELOPMENT SCENARIOS&

(planned) WORK AREAS FOR COST-TERRA

Main issuesPart I. High-level scenarios for CR business

Part II. Future work areas for COST-TERRA:Cataloguing and categorising CR Use CasesUnderstanding impact of TVWS regulationConsidering impact of CR Licensing SchemesCo-existence issues

High-level scenario planningNeed for scenarios for future development of CR

Scenarios to be limited in number and transcending the entrenchments of institutional mind-sets

To provide abstracted view of the overall CR business landscape and “eco-system”

To expose the most critical issues defining the development path for CR evolution

NB: “most critical” = beyond the will of any of the stakeholders in the field

e.g. regulatory regime in this context could not be seen as really critical unpredictable factor as it is adjustable under will of the respective governments, usually as co-evolutionary response to changing business and technological environment

COST-TERRA scenarios

Cost (complexity) of CR technology

Does a viable business case emerge for CR as enabler of new wireless service opportunities?

LOW

HIGH

NO YES

CHINA BOX TAKE-AWAY PARTY

RISE OF VINEYARDS

POLAR EXPEDITIONS PARTY AT DAVOS

Description of scenarios (I)“Polar expeditions” – this scenario would be characterised

by the absence of proven business opportunities for CR and high costs of technology (i.e. more or less the situation we see today)

In such environment it could be envisaged that the CR deployments would be limited to some experimental pilot deployments or, alternatively, employed by high demanding users that might value some benefits more than the costs (e.g. government applications, military)

Environmental response (policymakers, businesses) – being in stand-by and observing if any shift from this situation is likely

Year 2020 prediction for deployment of CR: Nowhere (did not leave laboratories; geeks)

Description of scenarios (II)“China box take-away party” – this scenario would be

characterised by the absence of proven business opportunities for CR within telco-grade services but yet availability of some affordable equipment

In such environment it could be envisaged that the CR developments would be limited to private/local deployment islets (“CR Hot-spots”), of which the TV White Space opportunistic deployments would be an obvious example

Environmental response (policymakers, businesses) – localised regulation, opportunities for small businesses (both on vendor and on service provision sides)

Year 2020 prediction for deployment of CR: Mass market but specific customers (e.g. machine-to-machine

(ITS (Intelligent Transport Systems); SRD in factory)

Description of scenarios (III)“Party at Davos” – this scenario would be characterised by

emergence of a viable business case(s) but developments being hampered by high costs (CAPEX)

In such environment it could be envisaged that the CR developments would be driven by a few rich market-players, e.g. big telcos or the likes of Apple or Google, who might use the new service opportunities provided by CR for entering new market segments or cementing their existing market positions regardless (at least for a while) of high initial costs

Environmental response (policymakers, businesses) – market/competition regulation, attempts at the international standardisation (global frequencies/standards), playground of big businesses

Year 2020 prediction for deployment of CR: Few niche markets (e.g. defence, R&D, high yield businesses)

Description of scenarios (IV)“Rise of vineyards” – this scenario would be characterised by

existence of a viable business case(s) and availability of affordable technologies

In such environment it could be envisaged that the number of market players would grow, yet it is likely that the high-tech specifics of technology would remain the barrier limiting the overall number of global market players to a certain number of regional or specialised providers

Environmental response (policymakers, businesses) – the international standardisation likely to get a boost (global frequencies/standards), rich and varied business eco-system

Year 2020 prediction for deployment of CR: Mass market and accessible to general population (e.g.

ubiquitous IP-based access to www) Intelligent devices rule

Part II: Future work areasThe following represents the ideas for the work areas and issues to be addressed by the COST-TERRA research community with the highest priority:

Cataloguing and categorising CR Use Cases

Understanding impact of TVWS regulation

Considering impact of CR Licensing Schemes

Co-existence issues

Cataloguing CR use cases It is important to catalogue and categorise the various CR

Use and Business Cases: different classes of use and business cases:

depending on licensing scheme depending on who keeps the infrastructure depending on “who pays” for services/infrastructure maintenance

dynamism of scenarios over time/changing environment apply tags to categorize use cases seek eventual refinement of CR definition: today multiple

definitions exist leading to confusion

As of today two types of scenario building: technical system configurations (as used in ETSI TC RRS,

OneFIT) business development scenarios (as reported by AaltoU) How to map these two to each other?

Ongoing TVWS regulationUnderstanding business cases?

Understanding the technical solutions for implementing the proposed regulatory schemes?

Co-existence between secondary users?

Role/relation/complementarity of geolocation database vs. sensing solutions?

Possibility of “exporting” TVWS regulatory solutions into other bands, e.g. with peer-to-peer communication where all transceiver could be detected more easily?

Impact of Licensing SchemesHow licensing scheme should interveawe into

business case and technology modelling: licensed? light-licensed (incl. database-interrogation-based

authorisations)?unlicensed?

How frequency band access regime come into picture:overlay (“white spaces” concept)?shared dedicated CR bands (ISM bands, commons)?self-managed CR bands?what about “underlay” (UWB-like)? Other innovative

combinations?

Co-existence issuesMapping needed between ETSI and IEEE coexistence

models/approaches?

Exploring the role of innovative techniques (FBMC, spectrum “sculpting”, else) in physical layer to facilitate co-existence?

Simultaneous multi-band CR operation?

Advanced co-existence (e.g. the one employing above methods) modelling in terms of probability of interference estimates?

Promotion of “self-regulation”/”good-neighbour” protocol concepts? Understanding of “cheating” risks in this context.

Common signalling/control approaches? IP-based Over-The-Air/wireline infrastructure for that?
