  1. Regional Radiocommunication Conference Information session Results of the second synthesis of the draft Plan Pham Nhu Hai PXT Team Leader Radiocommunication Bureau

  2. Second synthesis and beyond.. • Main features of the synthesis programs • Second synthesis • Input data • results • Conclusions RRC-06 Information session 15 May 2006 Geneva Switzerland

  3. RRC-06 DA VINCI CODE • Maximise assigned requirements/spectrum available • Unbiased – it does not know • Source of requirement • Types of requirement • Allotment or assignment • Single or linked set of requirements • DVB-T or T-DAB (Band III) RRC-06 Information session 15 May 2006 Geneva Switzerland

  4. The production of the draft Plan • Draft Plan (Case 1) • RRC-04 decisions • ATV & OPS included • 3 study cases (WPIPG) • ATV only (Case 2) • OPS only (Case 3) • Neither ATV nor OPS (Case 4) RRC-06 Information session 15 May 2006 Geneva Switzerland

  5. Input data (COM 5/1) • Digital requirements • Reference situation • ATV • OPS • Administrative declarations RRC-06 Information session 15 May 2006 Geneva Switzerland

  6. Digital requirements • Reference date: 31 October 2005 • 109 Member States and one observer (the Palestine Authority) submitted • The remaining 10 • AGL asked to convert ATV • ISL and SEY request NOT to generate • GNE,LBR,MWI,RRW,SOM,SRL and STP – PXT generated following advice of WPIPG RRC-06 Information session 15 May 2006 Geneva Switzerland

  7. Total requirements RRC-06 Information session 15 May 2006 Geneva Switzerland

  8. Requirements – Band III RRC-06 Information session 15 May 2006 Geneva Switzerland

  9. Requirements – Band IV & V RRC-06 Information session 15 May 2006 Geneva Switzerland

  10. Analogue TV - Total RRC-06 Information session 15 May 2006 Geneva Switzerland

  11. Analogue TV break-down RRC-06 Information session 15 May 2006 Geneva Switzerland

  12. Other primary services - Total RRC-06 Information session 15 May 2006 Geneva Switzerland

  13. OPS break-down RRC-06 Information session 15 May 2006 Geneva Switzerland

  14. Administrative declarations RRC-06 Information session 15 May 2006 Geneva Switzerland

  15. AD files and statistics All details can be found at http://www.itu.int/ITU-R/terrestrial/pub-reg/rrc/admdecl/index.html RRC-06 Information session 15 May 2006 Geneva Switzerland

  16. Band III – second synthesis RRC-06 Information session 15 May 2006 Geneva Switzerland

  17. Does the synthesis favour T-DAB? • Bandwidth: T-DAB < DVB-T • Protection criteria: T-DAB < DVB-T >> Fewer incompatibilities • Synthesis does not know the type of requirement >> statistically better chance of getting a frequency! >> results shown in some areas RRC-06 Information session 15 May 2006 Geneva Switzerland

  18. Band IV and V - Results RRC-06 Information session 15 May 2006 Geneva Switzerland

  19. Band IV&V – PE/DP1/DP2 in % RRC-06 Information session 15 May 2006 Geneva Switzerland

  20. Band III – Case 1 & 4 RRC-06 Information session 15 May 2006 Geneva Switzerland

  21. Band IV/V – Case 1 & 4 RRC-06 Information session 15 May 2006 Geneva Switzerland

  22. CNG 2 – Band IV/V RRC-06 Information session 15 May 2006 Geneva Switzerland

  23. CNG 3 – Band IV/V RRC-06 Information session 15 May 2006 Geneva Switzerland

  24. CNG 4 – Band IV/V RRC-06 Information session 15 May 2006 Geneva Switzerland

  25. CNG 5 – Band IV/V RRC-06 Information session 15 May 2006 Geneva Switzerland

  26. CNG 6&7 – Band IV/V RRC-06 Information session 15 May 2006 Geneva Switzerland

  27. Initial target used for synthesis • First planning exercise • Administrations with no requirements satisfied • IPG-1 and WP-IPG to • firstly determine a nominal maximum equal number • Normal synthesis continues RRC-06 Information session 15 May 2006 Geneva Switzerland

  28. PXT considerations • The use of a large target number for the synthesis process may result in • distorted distribution of assigned requirements for small geographical areas that include a number of administrations of significantly different geographical sizes. • The higher the target number the lower the overall number of satisfied requirements. RRC-06 Information session 15 May 2006 Geneva Switzerland

  29. PXT considerations • While a number between one to 21 could arbitrarily be used, it is difficult to justify with sound reasons why any such number is the most suitable, because of the differences in the planning configuration used by different administrations. • The higher a number that is used the more potential for distortion of the distribution of assigned requirements. RRC-06 Information session 15 May 2006 Geneva Switzerland

  30. PXT recommendation • The use of one as a target number, in order to avoid the situation where administrations may receive no assigned requirement, is recommended before the synthesis software continues to assign channels in an anonymous and maximising manner as originally designed. RRC-06 Information session 15 May 2006 Geneva Switzerland

  31. Conclusions • Results are getting better! More requirements satisfied • Band III still a challenge! • Impact of ATV on the overall results is significant • Impact of OPS on the overall results is not significant RRC-06 Information session 15 May 2006 Geneva Switzerland

  32. Conclusions (..) • Computers will NOT bring results!!! • You and only You will…. • Coordination and negotiation do not end at RRC-06 RRC-06 Information session 15 May 2006 Geneva Switzerland

  33. Thanks for your attention GOOD LUCK TO US ALL! RRC-06 Information session 15 May 2006 Geneva Switzerland
