21 Recommended preliminary coordination procedures

(1) Before a radiocommunications transmitter is included in the Register for a 2.3 GHz spectrum licence, the licensee should have regard to radiocommunications receivers included in the Register for other 2.3 GHz spectrum licences. (2) When planning to operate a fixed transmitter under a 2.3 GHz spectrum licence, the licensee should coordinate with any fixed receivers included in the Register for other 2.3 GHz spectrum licences. The coordination should: (a) use the details of each fixed receiver, as included in the Register; and (b) use the level of protection set out in the subsection 145(4) determination; and (c) use a suitable propagation model to model path loss between the fixed transmitter and each fixed receiver; and (d) take into account the terrain and any other relevant factors.

Note: Example for paragraph (c): The propagation model in the latest version of ITU-R Recommendation P.526 “Propagation by diffraction” is an example of a suitable propagation model.

(3) If such coordination indicates that harmful interference may occur to a fixed receiver as a result of operating the fixed transmitter, the licensee should consider: (a) replanning the fixed transmitter to avoid the harmful interference; or (b) negotiating with the licensee of the affected 2.3 GHz spectrum licence to find a resolution.
