transmissions in the broadcasting service

or in other primary terrestrial services

operating in conformity with the Radio

Regulations, …

Provision 5.1.3(cont.)

…provided that the peak power density

in any 4 kHz of the above-mentioned

notified assignments shall not exceed the

spectral power density in the same 4 kHz

of the digital entry in the Plan.

Coordination - Further remarks

� Coordinate early

� Coordinate regularly

� Mutual respect

� Good technical bases

�Identified as affected only the first step

�Use measurement data

16



31

Some more remarks

� Don’t forget administration outside GE06

�Establish criteria for coordination



GE06 is complex!

The Bureau are ready to assist!
