parameters of the radiocommunications receivers as recorded in the Register;

         (b)     use the level of protection set out in the subsection 145(4) Determination;

         (c)     make use of a suitable propagation model to model path loss between the fixed transmitters and radiocommunications receivers; and

         (d)     take into account terrain and any other relevant factors.

    Note An example of a suitable propagation model is that set out in section 4.5.2 of ITU-R Recommendation P.526-13 Propagation by diffraction.
      (3) In the event that coordination performed under subsection (2) indicates harmful interference may occur, spectrum licensees should consider:

         (a)      replanning the deployment of the fixed transmitters to avoid causing harmful interference; or

         (b)      negotiating with the affected spectrum licensee to find a resolution.
       (4)   In the event a solution under subsection (3) is not possible, interference is managed in accordance with any synchronisation requirement condition included in the spectrum licence, unless other arrangements are agreed to by the affected licensees.

    Note: For a device with an active antenna system, the radiated power in the direction of a receiver operated under another licence, is defined as the sum of the gain of the antenna towards in the direction of the receiver (accounting for azimuth and elevation) and the Total Radiated Power (dBm). This allowance is based on the assumption that beam pointing angles and/or power can be controlled dynamically to ensure a defined level of radiated power in a specific direction is not exceeded.

             Part 9 Earth station protection zones

      9.1 Background
      The ACMA has identified a number of locations that may be suitable as earth station protection zones (ESPZs) in eastern and western Australia. The purpose of these ESPZs is to define areas outside of reasonably sized population centres that provide long-term certainty and flexibility for investment in and operation of commercial space communications teleport facilities in Australia. The general protection requirements for these ESPZs are defined in RALI MS44.
      9.2 Protection requirements

      Radiocommunications transmitters operated under a spectrum licence in the 3.4 GHz band must comply with the coordination and protection requirements specified in RALI MS44.
           Note: The ACMA may vary RALI MS 44 to change the ESPZs.

              Part 10 Earth station facility near Uralla

      10.1 Background
      There is an Earth station facility located near Uralla (the Uralla facility) within the HCIS NU7K4. Services at the Uralla facility operate at various frequencies in the 3400-4200 MHz band.
      10.2 Protection requirements
      (1) Radiocommunications transmitters operated under a spectrum licence in the 3.4 GHz band must protect earth stations operating in the 3400-4200 MHz band at the Uralla facility to the levels specified in RALI MS44.

      Note 1: Given some of the services operating at the Uralla facility are temporal in nature and/or may only
