10  Accuracy
  Unless otherwise specified, the value of a parameter in Schedules 2 and 3 to this instrument must be estimated with a level of confidence not less than 95 percent that the true value of the parameter will always remain below the requirement specified in this instrument.

Schedule 1 Location of a transmitter
  (subsection 4(1))
   1. The location of a radiocommunications transmitter, (lt, Lt) is the location (by latitude and longitude with reference to GDA94) 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 GDA94) 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 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, available on the ACMA's website: www.acma.gov.au.

              Schedule 2 Device boundaries and device boundary criteria
  (subsection 4(1) paragraph 9(1)(c), subparagraphs 9(2)(b)(i), 9(3)(c)(i), 9(4)(b)(i) and section 10)

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 each of the integers from 2 through 530; and
      (b) n is each of the integer degrees from 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 transmitter (that is, with the lowest value of m) where either:
 (a) the device boundary criterion, RP-MP, is less than or equal to 0; or
 (b) m is equal to 530.

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