16
RRC-06 Information session 15 May 2006 Geneva Switzerland Band III – second synthesis
17
RRC-06 Information session 15 May 2006 Geneva Switzerland 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
18

26
RRC-06 Information session 15 May 2006 Geneva Switzerland CNG 6&7 – Band IV/V
27
RRC-06 Information session 15 May 2006 Geneva Switzerland 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
28
RRC-06 Information session 15 May 2006 Geneva Switzerland 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.
29
RRC-06 Information session 15 May 2006 Geneva Switzerland 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.
30
RRC-06 Information session 15 May 2006 Geneva Switzerland 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.
31
RRC-06 Information session 15 May 2006 Geneva Switzerland 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
32
RRC-06 Information session 15 May 2006 Geneva Switzerland Conclusions (..) Computers will NOT bring results!!! You and only You will …. Coordination and negotiation do not end at RRC-06
