Radiocommunications (Unacceptable Levels of Interference — 3.4 GHz Band) Determination 2015 Radiocommunications Act 1992 made under subsection 145(4) of the Radiocommunications Act 1992. Compilation No. 3 Compilation date: 27 June 2023 Includes amendments up to: F2023L00857 Prepared by the Australian Communications and Media Authority, Melbourne 1 Name of Determination This Determination is the Radiocommunications (Unacceptable Levels of Interference — 3.4 GHz Band) Determination 2015. 4 Purpose This Determination is made for the purposes of section 145 of the Act and sets out what is an unacceptable level of interference caused by a radiocommunications transmitter operating under a spectrum licence issued in the 3.4 GHz band, so as to ensure that high levels of emission from radiocommunications transmitters operated under a spectrum licence are kept within the geographic area and frequency band of the licence. Note 1 Under section 145 of the Act, the ACMA may refuse to register a radiocommunications transmitter if it is satisfied that the operation of the radiocommunications transmitter could cause an unacceptable level of interference to the operation of other radiocommunications devices under that or any other spectrum licence, or any other licence. Note 2 The ACMA information paper, Registration of radiocommunications devices under spectrum licences, (available on the ACMA website: www.acma.gov.au), provides further information about the registration of radiocommunications transmitters under Part 3.5 of the Act. Note 3 The ACMA has issued written advisory guidelines under section 262 of the Act about compatibility requirements in relation to the assignment of frequencies to radiocommunications transmitters operated under apparatus licences and the operation of radiocommunications transmitters under spectrum licences. The ACMA will take these guidelines into account during the settlement of interference disputes. Each case will be assessed on its merits. The guidelines do not prevent a licensee negotiating other compatibility requirements with another licensee. The guidelines are: * Radiocommunications Advisory Guidelines (Managing Interference from Spectrum Licensed Transmitters — 3.4 GHz Band) 2015; and * Radiocommunications Advisory Guidelines (Managing Interference to Spectrum Licensed Receivers — 3.4 GHz Band) 2015.

(6) This section does not apply in relation to a radiocommunications transmitter to which section 11 applies. Note Subsection 145(1) of the Act provides that the ACMA may refuse to include in the Register details of a radiocommunications transmitter if the ACMA is satisfied that operation of the transmitter could cause an unacceptable level of interference to the operation of other radiocommunications devices. However, some radiocommunications transmitters are exempt from the requirement to be registered in the Register under a 3.4 GHz band spectrum licence – see subsection 69(2) of the Act. Accordingly, these transmitters are not required to meet the device boundary criterion specified in this Determination. 10 Accuracy Unless otherwise specified, the value of a parameter in Schedules 2 and 3 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 Determination. 11 Transition – radiocommunications transmitter registered before commencement of this section (1) If a radiocommunications transmitter was included in the Register in relation to a spectrum licence in the 3.4 GHz band before the commencement of this section (relevant transmitter), this section applies in relation to that transmitter. (2) Subject to subsection (3), for the purposes of subsection 145(4) of the Act, a level of interference caused by a relevant transmitter is unacceptable if it would have been unacceptable under this Determination as in force at the time the relevant transmitter was included in the Register. Note This Determination, and previous versions of this Determination, can be obtained, free of charge, from the Federal Register of Legislation: www.legislation.gov.au. (3) For the purposes of subsection 145(4) of the Act, if: (a) after the commencement of this section, both: (i) a detail of a relevant transmitter changes (relevant change); and (ii) the change to the detail is recorded in the Register; and (b) the distance of the new device boundary of the relevant transmitter is, on each radial mentioned in Part 1 of Schedule 2, equal to or less than the distance of the old device boundary of the relevant transmitter on that radial; and (c) but for the effect of this subsection, a level of interference caused by the relevant transmitter, immediately after the change time, would be unacceptable; the level of interference caused by the relevant transmitter, immediately after the change time, is not unacceptable because of the relevant change.

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 in the group. Note: n is the bearing of the nth-degree radial for the group of radiocommunications transmitters. Part 2 Device boundary criterion 1. The device boundary criterion is the value of the mathematical expression: RP – MP where: MP : is PL(lmn,Lmn) + LOP – Gr; RP : is the horizontally radiated power, measured in dBm EIRP per MHz, for each bearing, σn; Note For a device with an active antenna system, the RP at bearing σn is defined as the sum of the gain of the antenna towards the horizontal plane and towards azimuth σn (dB) and the total radiated power (dBm). This allowance is based on the assumption that beam pointing angles and/or power can be controlled dynamically to ensure RP is not exceeded. LOP : is the level of protection. For radiocommunications transmitters with AAS, the LOP is -90 dBm per MHz. For radiocommunications transmitters without AAS, the LOP is –98 dBm per MHz; Gr : is the nominal radiocommunications receiver antenna gain including feeder loss set to 0 dBi; PL(lmn,Lmn) : is the propagation loss (dB) set out in Part 3 of the mth increment on the nth radial. Part 3 Calculation of propagation loss 1. Subject to this Part 3, the propagation loss (or PL(lmn,Lmn)), for a radiocommunications transmitter, of the mth increment on the nth radial is calculated using: (a) for a transmitter connected to an antenna which is located greater than 6 metres above ground level – the method and parameters defined in section 2.2 of Recommendation ITU-R P.525-4 and in section 4.5.2 of Recommendation ITU-R P.526-15; or (b) for a transmitter connected to an antenna which is located at or below 6 metres above ground level – the method and parameters defined in section 2.2 of Recommendation ITU-R P.525-4, in section 4.5.2 of Recommendation ITU-R P.526-15 and in section 3.2 of Recommendation ITU-R P.2108-0. 2. In implementing the method in section 4.5.2 of Recommendation ITU-R P.526-15, the height of the nominal receiver is 5 metres above ground level, the height of the transmitter above ground level is determined in Part 1 of Schedule 3, and the height of a profile point is determined in Part 2 of Schedule 3. 3. In implementing the method in section 4.5.2 of Recommendation ITU-R P.526-15, the path profile is developed by sampling the DEM-3S at 100 metre increments along each radial. At each increment along the path profile, the procedure for determining the average ground height described in Part 2 of Schedule 3 is implemented. 4. In implementing the method in section 3.2 of Recommendation ITU-R P.2108-0: (a) the percentage of locations is set at 0.08% and the correction is applied at only one end of the path; and (b) if the loss calculated using the method in section 3.2 of Recommendation ITU-R P.2108-0 is less than 0 dB, the calculated loss value is replaced with 0 dB; and (c) if the loss calculated using the method in section 3.2 of Recommendation ITU-R P.2108-0 is greater than 8 dB, the calculated loss value is replaced with 8 dB. Schedule 3 Antenna height and average ground height (section 10, Schedule 2) Part 1 Antenna height of a transmitter 1. The antenna height of a fixed transmitter, is the vertical height in metres of the phase centre of the transmitter's antenna measured with an error of less than 5 parts in 100 and relative to the point: (a) located on the line of intersection between the external surface of the structure supporting the antenna and the surface of the ground or sea; and (b) having the lowest elevation on that line. 2. For a group of radiocommunications transmitters, the antenna height for the group is the greatest of the heights of each individual transmitter in the group, calculated in accordance with this Part. Part 2 Average ground height 1. The average ground height for the mth increment on the nth radial is calculated as follows: Step 1: determine the associated latitude and longitude (lmn,Lmn) of the mth increment on the nth radial as calculated in Part 3. Step 2: identify the DEM-3S cell represented by the latitude and longitude of the mth increment on the nth radial. Step 3: bound the identified DEM-3S cell with the 8 adjacent DEM-3S cells in a 3x3 matrix and obtain each DEM-3S cell height attribute (as shown in Diagram 1). Step 4: determine the average value of height from the 3x3 matrix. 2. If the seconds component of (lmn,Lmn), plus 1.5, has a modulus of zero when divided by 3, then the corresponding DEM-3S cell, for the purposes Step 2 in item 1, is the adjacent DEM-3S cell with the minimum height. Diagram 1 Calculating average ground height Part 3 Vincenty's Formulae Note This implementation of Vincenty's Direct Formulae uses the parameters {a, f1, b} from the GRS80 ellipsoid as referenced by the Geocentric Datum of Australia 1994 (GDA94). 1. In calculating (lmn,Lmn): lt : is the latitude of the fixed transmitter (decimal radians) Lt : is the longitude of the fixed transmitter (decimal radians) α : is the azimuth angle (decimal radians) d : is the separation distance to required point (m×100 metres) a : is the semi-major axis with value 6378137 metres fl : is the flattening of the value 1/298.25722210 b : is the semi-minor axis of (a×(1-fl)) 2. Using an initial value, iterate the following three equations until the change in ϕ is less than 10-12. 3. Then: Note use the four-quadrant inverse tangent, atan2. Note use the four-quadrant inverse tangent, atan2. Schedule 4 Earth station protection zones (subsection 9(3)) Description of Area 1.
