Results in RRC countriesResults 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


Elements impact on the resultsElements 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)


More important element..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)


More important elements…More important elements…

Submissions of administrative declarations, both internal and with neighbouring countries which can, for example, take account of realistic terrain features.


Less important elementsLess important elements

Test points/reference networks in the sea

Assignments and/or allotments for very large service areas


How many coverage?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;


One recommendationOne 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.


Plan for very large service area Plan for very large service area assignments/allotments?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’


Three sure ways to achieve better resultsThree sure ways to achieve better results

1. Coordination

2. Negotiation
