  14. Planning process • Analysis • Acceptable channels • Potentially available channels • Compatible/incompatible requirements • Synthesis • Order requirements • Assigning channel RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  15. Band III - Results RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  16. Band III – Your results RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  17. Band IV and V - Results RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  18. Band IV and V – Your results RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  19. Analysis – Impact of OS and BC • Case 1 – OS and BC – 104569 available channels identified • Case 4 – No OS and No BC – 407602 available channels identified • OS and BC ‘consume’ nearly ¾ spectrum available • 2 coverage is expected if taking OS and BC into account RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  20. Band III - Case1 (OS and BC) • 9582‘requirements’ for synthesis • 4474 (~47%) without available channels => not assigned with a channel. • Some of these may be submitted with one or few acceptable channel. • 2.7 available channel for each requirement • 25 incompatibilities for each requirement RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  21. Band III - Case1 (OS and BC) • 9582‘requirements’ for synthesis • 330 (3%) have no incompatibility • 4067 (~42%) with 1 available channel and between 1 to 214 incompatibilities • If many incompatibilities => unlikely assigned with a channel • As many as 227 IC for a requirement RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  22. Band III – Case 4 (No OS/BC) • 9582‘requirements’ for synthesis • 991 T-DAB with 32 available channels • 6 available channels for each requirement • 75 ncompatibilities for each requirement • As many as 607 ICs for a requirement RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  23. Band III – Case 4 (No OS/BC) • 9582‘requirements’ for synthesis • All requirements have at least 1 AC • 1678 – No IC => get a channel • 1665 – only 1 AC => get a channel => coordinated well • 5962 (~63%) with 1 available channel and between 1 to 379 incompatibilities • If many incompatibilities => unlikely assigned with a channel RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  24. Band IV/V - Case1 (OS and BC) • 38602‘requirements’ for synthesis • 13534 (~35%) without available channels => not assigned with a channel. • Some of these may be submitted with one or few acceptable channel. • 1081 with 49 available channels RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  25. Band IV/V - Case1 (OS and BC) • 38602‘requirements’ for synthesis • 3274 (<10%) have no incompatibility • 18881 (~49%) with 1 available channel and between 1 to 300 incompatibilities • If many incompatibilities => unlikely assigned with a channel RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  26. Band IV/V – Case 4 (No OS/BC) • 38602‘requirements’ for synthesis • 7207 with 49 available channels • Each AC requested by 7800-8400 requirements –‘evenly’requetsed RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  27. Band IV/V – Case 4 (No OS/BC) • 38602‘requirements’ for synthesis • All requirements have at least 1 AC • 11948 – No IC => get a channel • 11866 – only 1 AC => get a channel => coordinated well • 28521 (~74%) with 1 available channel and between 1 to 1170 incompatibilities • If many incompatibilities => unlikely assigned with a channel RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  28. Results in RRC countries • High percentage of requirements assigned with channels • coordination activities • Administrative declarations • Areas where channels not assigned <= protection of analogue services (unintended) • Some border areas – low success rate need more studies RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  29. Elements impact on the results • Excessive input requirements for the available spectrum and errors in the preparation and submission of input requirements by administrations • Internal incompatibilities between requirements and existing assignments/requirements (from the same countries) RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  30. More important element.. • Modification to planning software to enable some intervention in the “random” approach in the synthesis process => equitable access • Very high transmitter power assignments (sometimes linked with allotments) RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  31. More important elements… • Submissions of administrative declarations, both internal and with neighbouring countries which can, for example, take account of realistic terrain features. RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  32. Less important elements • Test points/reference networks in the sea • Assignments and/or allotments for very large service areas RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  33. How many coverage? • in Band III, sharing between T-DAB and DVB-T services, a possible target could be one (1) DVB-T and three (3) T-DAB • in Bands IV and V, a nominal target of 6-7 layers may be possible; • in areas of extreme propagation conditions, the number of layers is expected to be less; RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  34. One recommendation • First - identify areas where there are a large number of incompatibilities • Consider how to resolve these incompatibilities. • This was found to an effective planning approach by some administrations. RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  35. Plan for very large service area assignments/allotments? • consider the potential of self interference and interference to the neighbouring areas; • combination of small and large allotments in the same geographical area is likely to result in unbalanced distribution of channels; • the size of an allotment area should generally be slightly greater than the co-channel ‘reuse distances’ RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  36. Three sure ways to achieve better results • Coordination • Negotiation • Coordination and Negotiation RRC information meeting and workshop - Damascus, Syria 16-18 August 2005

  37. Thanks for your attention RRC information meeting and workshop - Damascus, Syria 16-18 August 2005
