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

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
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
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
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
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
Conclusions (..)

Computers will NOT bring results!!!

You and only You will….

Coordination and negotiation do not
end at RRC-06

Thanks for your attention
GOOD LUCK TO US ALL!
