Organisations, Industry)  Nearly 145 years old (17-05-1865)  Worldwide harmonisation of, co-operation in, and development of telecommunications 3 11 May 2009 IBBTWRC-07 Workshop
  • 4. Radio Regulations (RR’s)  ITU activities are based on an international treaty ( Constitution and Convention)  Binding Complementary parts:   Radio Regulations   International Telecommunications Regulations  Radio Regulations have treaty status 4 11 May 2009 IBBTWRC-07 Workshop
  • 5. Objectives of RR’s   Promote international co-operation for improvement of telecommunications of all kind:   Allocation of spectrum   Orbital Positions   Allotments of frequencies   Registration of Assignments both for Terrestrial and Space Services 5 11 May 2009 IBBTWRC-07 Workshop
  • 6. RR’s: to avoid problems  Radio Regulations concern relations between countries  If no risk for interference, no need, but  Radio waves don’t stop at borders  One has to co-ordinate orbital positions, and  Trade is international, and  There is a need for common language 6 11 May 2009 IBBTWRC-07 Workshop
  • 7. RR’s: to enjoy benefits  Worldwide use, e.g. Maritime  Harmonisation, e.g. IMT  Common sharing criteria, e.g. UWB  Common protection criteria, e.g. Passive Services  Common procedures, e.g. Satellites  Common approach to new technology, e.g. BWA or CR 7 11 May 2009 IBBTWRC-07 Workshop

  • 9. 7 Committees  1: Steering  2: Credentials  3: Budget  4, 5 and 6: On Substance  Each of these creates Working Groups  7: Editorial 9 11 May 2009 IBBTWRC-07 Workshop
  • 10. The formal process Negotiation process The formal Plenary Plenary process is strictly hierarchical Committee Committee WG WG DG DG 10 11 May 2009 IBBTWRC-07 Workshop
  • 11. The informal process  Stamina: lengthy negotiation process, late night sessions  An informal process may exist in making a deal:  including an issue not for ITU  on issues covered by the agenda  Package deal: We give you a bit more on this item, and you get a bit less of that one ! 11 11 May 2009 IBBTWRC-07 Workshop
  • 12. Some Non-technical problems  Palestine / Israel  Cuba / USA  State monopoly / private industry  Poor / rich  Culture  Conservative / innovative  Cost of technology /cost of labour  International or national only Broadcast 12 11 May 2009 IBBTWRC-07 Workshop
  • 13. Preparing a WRC 6 Regional Organisations:  CEPT (Europe)  RCC (ex Sovjet)  CITEL (N + S America)  APT (Asia)  League of ARAB States  ATU (Africa) 13 11 May 2009 IBBTWRC-07 Workshop
  • 14. Agenda setting: Criteria  Worldwide or regional character  Need for changes in the RR  Required Studies should be completed   Resources required should remain manageable  Not yet at two successive preceding conferences 14 11 May 2009 IBBTWRC-07 Workshop
  • 15. Agenda setting: Proposals Some standard items +  CEPT 22  Arab States 15  CITEL ≈ 14  RCC ≈ 10  USA ≈ 21  Many proposals from individual admin.’s  Much common, but still large variety 15 11 May 2009 IBBTWRC-07 Workshop
  • 16.  CEPT: 1.17: to consider spectrum requirements and a global allocation to support cognitive radio systems in the context of heterogeneous radio networks environment, based on the results of ITU- R studies, in accordance with Resolution [EUR/ 10A25/12] (WRC-07)  ARAB: 1.10: to consider spectrum requirements and global allocation to support cognitive radio systems and/or radio software systems based on results of ITU-R studies 16 11 May 2009 IBBTWRC-07 Workshop
  • 17. To Negotiate  On support, and priority  On text of Agenda Item and Resolution  CEPT : SDR in ITU-R Recommendations  ARAB: SDR in Agenda, or no agenda item 17 11 May 2009 IBBTWRC-07 Workshop
  • 18. Interim result To consider spectrum related matters and regulatory measures to enable the introduction of cognitive radio systems and/or self configuring / software defined radio networks, based upon the results of ITU-R studies, in accordance with Resolution [EUR/10A25/12] (WRC-07) 18 11 May 2009 IBBTWRC-07 Workshop
  • 19. Result  WRC-11 Agenda item 1.19: To consider regulatory measures and their relevance, in order to enable the introduction of software defined radio and cognitive radio systems based upon the results of ITU-R studies, in accordance with Resolution 956 (WRC-07)  Support by CEPT, ARAB, RCC  Neutral: Africa  No support from APT,  US, Can and Aus: can be done in SGs 19 11 May 2009 IBBTWRC-07 Workshop
  • 20. Resolution 956 (WRC-07) resolves to invite ITU-R 1) to study whether there is a need for regulatory measures related to the application of cognitive radio system technologies; 2) to study whether there is a need for regulatory measures related to the application of software-defined radio, resolves further that WRC-11 considers the results of these studies and takes the appropriate actions. 20 11 May 2009 IBBTWRC-07 Workshop
  • 21.   At ITU-R level – Working Party 1B of Study Group 1 Concerned groups: SG3, SG4, SG5, SG6, SG7   At CEPT level – CPG PTA 21 11 May 2009 IBBTWRC-07 Workshop
  • 22.  CEPT will actively contribute to regulatory studies within the ITU-R to investigate this issue before defining any position on this Agenda Item.  Software-defined radio and cognitive radio system are not radio services as listed in Article 1 of the Radio Regulations.  Software-defined radio and cognitive radio system may be operated under any radio services.  Europe is of the view that frequencies or frequency bands (tuning range) for specific applications can be harmonised regionally by regional telecommunications organizations or on world wide basis in ITU-R Recommendations. 22 11 May 2009 IBBTWRC-07 Workshop
  • 23. 1)  SDR and CRS are technologies that may allow more efficient use of the spectrum by any number of radiocommunications but are not radiocommunication services; such in accordance with RR No. 1.16; allocations are made only to radiocommunication services or the radio astronomy service; 2)  SDR and CRS are two capabilities related to equipment which can be combined. 3)  Comments from concerned groups. 23 11 May 2009 IBBTWRC-07 Workshop
  • 24. WP 1B: Definition SDR A radio in which the RF parameters including, but not limited to, frequency range, modulation type, or output power can be set or altered by software, and/or the technique by which this is achieved. NOTE 1 – Excludes changes to operating parameters which occur during normal pre‑installed and predetermined operation of a radio according to a system specification or standard. NOTE 2 – SDR is implementation technique applicable to many technologies and standards. NOTE 3 – SDR techniques are applicable to both transmitter and receivers.” 24 11 May 2009 IBBTWRC-07 Workshop
  • 25. WP 1B: Definition CRS (1) A radio system that has the capabilities: – to obtain the knowledge of radio operational environment and established policies and to monitor usage patterns and users’ needs; – to dynamically and autonomously adjust its operational parameters and protocols according to this knowledge in order to achieve predefined objectives, e.g. more efficient utilization of spectrum, and – to learn from the results of its actions in order to further improve its performance. 25 11 May 2009 IBBTWRC-07 Workshop
  • 26. WP 1B: Definition CRS (2) NOTE 1 – Radio operational environment encompasses radio and geographical environments, and internal states of the Cognitive Radio System. NOTE 2 – To obtain knowledge encompasses, for instance, by sensing the spectrum, by using knowledge data base, by user collaboration, or by broadcasting and receiving of control information. NOTE 3 – Cognitive Radio System comprises a set of entities able to communicate with each other (e.g. network and terminal entities and management entities).” 26 11 May 2009 IBBTWRC-07 Workshop
