incumbent FSS Earth receive stations operating in the 3600-3800 MHz band under earth receive licences
      (1) An incumbent earth receive station is one that operates in the 3600–3800 MHz band under an earth receive licence and falls within one of the frequencies and areas contained in the following re-allocation declarations:

          (a) Radiocommunications (Spectrum Re-allocation—3.6 GHz Band for Adelaide and Eastern Metropolitan Australia) Declaration 2018;

          (b) Radiocommunications (Spectrum Re-allocation—3.6 GHz Band for Perth) Declaration 2018;

          (c) Radiocommunications (Spectrum Re-allocation – 3.6 GHz Band for Regional Australia) Declaration 2018;

          (d) Radiocommunications (Spectrum Re-allocation – 3.4 GHz and 3.7 GHz Bands) Declaration 2022.
(2) Incumbent earth receive stations are to be provided with the protection defined in section 4.2 and section 4.3 of these guidelines.
(3) Incumbent earth receive stations within 300 km of a transmitter operated under a 3.4 GHz spectrum licence are also to be protected from co-channel emissions to a maximum interference level of -119.9 dBm/MHz not to be exceeded for more than 0.005% of the time.
           Note 1: Details of earth receive stations and site ID's are contained on the Register of Radiocommunications Licensees, accessible at www.acma.gov.au.

           Note 2: Refer to Recommendation ITU-R SF.1006 for further guidance on the procedure to use for the protection of FSS Earth receive stations.

      4.5 Protection requirements – FSS Earth receive stations operating in the 3750-4000 MHz band under area-wide receive licences
      (1) Radiocommunications transmitters operated under a spectrum licence in the 3.4 GHz band must protect earth receive stations from receiver overload, if the radiocommunications receiver for the earth receive station:

          (a) was included in the Register, in relation to an area-wide receive licence, before the date on which the radiocommunications transmitter operated under the spectrum licence is registered; and

          (b) is operated in accordance with that area-wide receive licence; and

          (c) is located within 100 km of the radiocommunications transmitter.
      (2) A radiocommunications transmitter operated under a spectrum licence in the 3.4 GHz band is not considered to overload the receiver of an earth receive station mentioned in subsection (1) if the total power received from the transmitter at the input of the earth receive station (after considering antenna gain, radiofrequency filtering and other losses) does not exceed a total of -65 dBm. The minimum radiofrequency filtering level described in Table 3, at the front end of the earth receive station for different frequency offsets, is assumed to apply at each lower limit for a licence and upper limit for a licence.

Frequency offset from lower or upper limit of licence for receiver of earth receive station (MHz)  Rejection (dB)
< 80                                                                                               60
≥ 80                                                                                               70
