are defined in the subsection 145(4) Determination:
           *  centre frequency
           *  device boundary
           *  device boundary criterion
           *  fixed receiver
           *  fixed transmitter
           *  geographic area

      (3) In these guidelines, a reference to a part of the spectrum, a frequency band or a frequency range includes all frequencies that are greater than but not including the lower frequency, up to and including the higher frequency.
Note: This means the lower number in the reference to a part of the spectrum, a frequency band or a frequency range is not included in the part of the spectrum, the frequency band or the frequency range.

      1.5 References to other instruments
In these guidelines, unless the contrary intention appears:
(a) a reference to another legislative instrument is a reference to that other legislative instrument as in force from time to time; and
(b) a reference to any other kind of instrument or writing is a reference to that other instrument or writing as in force or existing from time to time.
            Note 1: For references to Commonwealth Acts, see section 10 of the Acts Interpretation Act 1901; and see also subsection 13(1) of the Legislation Act 2003 for the application of the Acts Interpretation Act 1901 to legislative instruments.
            Note 2: All Commonwealth Acts and legislative instruments are registered on the Federal Register of Legislation and are accessible, free of charge, at www.legislation.gov.au.
            Note 3: See section 314A of the Act.

Part 2 Background

      2.1 A spectrum licence refers to a frequency band and a geographic area.  Interference occurring between adjacent spectrum licences consists of:
          * in-band interference, across the geographic boundaries; and
          * out-of-band interference, across the frequency boundaries.

      2.2 This interference is managed by creating emission buffer zones along the geographic and frequency boundaries of the licence, using a number of provisions of the Act.  These include:
          * the core licence conditions that all spectrum licences are subject to (see section 66 of the Act), about:
             * emission limits outside the geographic area; and
             * emission limits outside the frequency band;
          * the applicable determination under subsection 145 (4) of the Act about what constitutes unacceptable levels of interference; and
          * advisory guidelines made under section 262 of the Act, about managing interference in specific circumstances.

      Part 3 Managing interference from other services

      3.1 In-band interference

      (1) In-band interference caused in a radiocommunications receiver operating under a spectrum licence in the 3.4 GHz band by a radiocommunications transmitter operating under an adjacent spectrum licence issued on or after 14 December 2015 is managed by:

         (a)       the core conditions imposed on the spectrum licences under section 66 of the Act;

         (b)      the device boundary criteria and deployment constraints prescribed in the subsection
