Initial target used for synthesisInitial target used for synthesis

First planning exercise– Administrations with no requirements

satisfiedIPG-1 and WP-IPG to

– firstly determine a nominal maximum equal number

– Normal synthesis continues


PXT considerationsPXT 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.


PXT considerationsPXT 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.


PXT recommendationPXT 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.


ConclusionsConclusions

Results are getting better! More requirements satisfied

Band III still a challenge!Impact of ATV on the overall results

is significantImpact of OPS on the overall results

is not significant


Conclusions (..)Conclusions (..)

Computers will NOT bring results!!!

You and only You will….

Coordination and negotiation do not end at RRC-06


Thanks for your attentionThanks for your attention

GOOD LUCK TO US ALL!
