12  Background
 (1) Area-wide licences authorise the operation of radiocommunications devices in the frequency ranges 24.7 GHz–25.1 GHz and 27.5 GHz–30 GHz Australia wide, and in the 26 GHz band outside of the geographic areas subject to 26 GHz band spectrum licensing. Frequency assignment instructions and technical arrangements for area-wide licences are set out in RALI MS 46.
 (2) Radiocommunications transmitters operated under a spectrum licence in the 26 GHz band have the potential to cause interference to adjacent-area and adjacent-band area-wide licensed receivers.
 (3) The device boundary criterion, as defined in the Subsection 145(4) Determination, is the primary mechanism for managing interference across geographical boundaries. However, at times it may be necessary for licensees operating radiocommunications transmitters in the 26 GHz band to negotiate with area-wide licensees when deploying services in order to avoid harmful interference.
 (4) The primary mechanism for managing interference across frequency boundaries is adherence to the unwanted emissions limits defined in the 26 GHz band spectrum licence. However, as the technical frameworks for 26 GHz band spectrum licences and area-wide licences are optimised for services which operate in the time-division duplex mode, there is potential for interference even when devices comply with those limits. Therefore, at times it may be necessary for spectrum licensees operating radiocommunications transmitters in the 26 GHz band to negotiate with area-wide licensees when deploying services in order to avoid harmful interference.
 (5) The procedures detailed in section 13 are to be used to guide the management of both adjacent-area and adjacent-band interference from radiocommunications transmitters operated under a spectrum licence in the 26 GHz band to receivers that are both:
(a) receiving communications from a transmitter operated under an area-wide licence in or adjacent to the 26 GHz band; and
(b) located in the geographic area authorised by the area-wide licence.
  The ACMA will take the application of these procedures into account when resolving an interference dispute.
