3. FUTURE CR DEVELOPMENT SCENARIOS& (planned) WORK AREAS FOR COST-TERRA

4. Main issues Part I. High-level scenarios for CR business Part II. Future work areas for COST-TERRA: Cataloguing and categorising CR Use Cases Understanding impact of TVWS regulation Considering impact of CR Licensing Schemes Co-existence issues

5. High-level scenario planning Need 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

6. COST-TERRA scenarios Cost (complexity) of CR technology POLAR EXPEDITIONS PARTY AT DAVOS HIGH CHINA BOX TAKE-AWAY PARTY RISE OF VINEYARDS LOW NO YES Does a viable business case emerge for CR as enabler of new wireless service opportunities?

7. 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)

8. 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)

9. 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)

10. 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

11. Part II: Future work areas The 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

12. 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?

13. Ongoing TVWS regulation Understanding 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?

14. Impact of Licensing Schemes How 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?

15. Co-existence issues Mapping 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?
