assignment criteria for each frequency band and specifies protection ratios.
 (2) RALI FX 3 is subject to continuing review in consultation with industry, to incorporate improved assignment techniques and changing technology requirements.  Particular account is taken of changes in ITU-R Recommendations and standards made by other bodies.  As revisions seek to improve spectrum access opportunities, without undue detriment to current licensees, users of RALI FX 3 are urged to consult the current version when planning systems, to increase spectrum productivity.
3.2 Protection requirements
(1) The protection requirements for point-to-point fixed service receivers are specified in RALI FX 3 and apply to radiocommunications transmitters operated under a spectrum licence that were registered in the Register after the date of issue of the apparatus licence under which the receiver operates.
(2) In planning for the operation of radiocommunications transmitters under a spectrum licence in the 3.4 GHz band, spectrum licensees are to provide a level of out-of-band and in-band protection from those transmitters as would be provided from apparatus licensed fixed service transmitters whose frequencies are assigned in accordance with RALI FX 3.

         Part 4 Fixed satellite service Earth receive stations

4.1 Background
  Fixed satellite service (FSS) Earth receive stations operate across the 3400-4200 MHz band. The Spectrum Plan allocates the 3400-3600 MHz and 3600-4200 MHz bands to the FSS on a secondary and primary basis respectively.

      4.2 Protection requirements – FSS Earth receive stations operating in the 3400-3600 MHz band under earth receive licences
(1) As indicated in section 12 of Part 1 to the Spectrum Plan, a secondary service:
          * must not cause interference to a primary service, irrespective of who was operating first-in-time;
          * cannot claim protection from harmful interference caused by a primary service.
(2) Radiocommunications transmitters operated under a spectrum licence in the 3.4 GHz band in accordance with the conditions of the licence, are not taken to cause unacceptable interference to FSS Earth receive stations operating in the 3400-3600 MHz band.
(3) In planning for the operation of fixed transmitters under a spectrum licence in the 3.4 GHz band, before registering devices, spectrum licensees must notify the licensee of an FSS Earth receive station if frequency coordination indicates that interference may occur. This gives notice to the affected FSS licensee to implement mitigation measures, implement alternative arrangements for the delivery of their service or negotiate with the relevant spectrum licensee for the continued operation of their service.
         Note   Where practical, spectrum licensees are encouraged to work with incumbent FSS Earth receive licensees to resolve any interference issues.

      (1) Radiocommunications transmitters operated under a spectrum licence in the 3.4
