Determination as in force at the change time.

   old device boundary, of a relevant transmitter, means the device boundary of the transmitter established immediately before the change time, in accordance with this Determination as in force at the registration time.

   registration time, for a relevant transmitter, means the time the transmitter was included in the Register.

Schedule 1 Location of a transmitter

         (subsections 5(1), 7(3) and 8(3))

   1. The location of a radiocommunications transmitter, (lt, Lt) is the location (by latitude and longitude with reference to the Geocentric Datum of Australia 1994) of the phase centre of the radiocommunications transmitter's antenna.
   2. The location of a group of radiocommunications transmitters, (lt, Lt) is the location (by latitude and longitude with reference to the Geocentric Datum of Australia 1994) of the centre point between the phase centre of each radiocommunications transmitter antenna within the group.

   3. In determining the location of a radiocommunications transmitter, or a group of radiocommunications transmitters, the measurement error should be less than 10 metres.

    Note 1 The ACMA issues site identifiers for established radiocommunications locations available in the Register.

    Note 2 The ACMA provides advice on its website at www.acma.gov.au to assist licensees in determining the location and measurement error of a transmitter site in the document Business Operating Procedure (BOP) – Radiocommunications site data requirements.
Schedule 2 Device boundaries and device boundary criteria
           (subsections 5(1), 9(1), 9(2), 9(3), 9(4) and 9(5), section 10, and subsection 11(3))
      Part 1 Device boundary of a transmitter

    1. The device boundary of a single radiocommunications transmitter is established as follows:
    Step 1: Calculate the device boundary criterion at each m×100 metre increment along each of the n-degree radials, where:
    (a) m is the values 2 through 1010; and
    (b) n is the values 0 (true north) through 359.
    Step 2: For each radial, find the latitude and longitude of the first point on the radial, moving away from the location of the radiocommunications transmitter (that is, with the lowest value of m), where either:
    (a) RP-MP is less than or equal to 0; or
    (b) m is equal to 1010.

     This point is the end point of the radial.
    Step 3: The end point of each radial is the device boundary of the radiocommunications transmitter connected to that radial.
Note:  RP-MP (device boundary criterion) is calculated under Part 2.

      2.  For a group of radiocommunications transmitters the device boundary is to be calculated as if for a single radiocommunications transmitter. The radiated power (RP) for groups of radiocommunications transmitters is taken:
       (a) to be equal for each bearing σn; and
           (b) to have a value that is the maximum horizontally radiated power, in any direction, of any radiocommunications transmitter
