This Determination is the Radiocommunications (Unacceptable Levels of Interference — 1800 MHz Band) Determination 2012.

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 1800 MHz 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: 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 — 1800 MHz Band) 2012;

·Radiocommunications Advisory Guidelines (Managing Interference to Spectrum Licensed Receivers — 1800 MHz Band) 2012; and

·Radiocommunications Advisory Guidelines (Additional Device Boundary Criteria — 1800 MHz Lower Band) 2012.

However, some radiocommunications transmitters are exempt from the requirement to be registered in the Register under their 1800 MHz 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.

Schedule 2 Device boundaries

(subsection 5(1), 9(1) and 9(2), 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 the values 1 through 400; 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 (lowest value of m) where either:

(a) RP-MP is less than or equal to 0; or

(b) m is equal to 400.

Step 3: The end point of each radial is the device boundary of the radiocommunications transmitter.

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 σ_n; and
(b) to have a value that is the maximum horizontally radiated power, in any direction, of any radiocommunications transmitter in the group.

Notes_n is the bearing of the n^th-degree radial for the group of radiocommunications transmitters.

Part 2 Device boundary criterion

The device boundary criterion is the value of the mathematical expression:

RP-MP
where:

MP

:

is PL(l_mn,L_mn) + LOP - G_r

RP

:

is the horizontally radiated power, measured in dBm EIRP per 30 kHz, for each bearing, σ_n,

LOP

:

is the level of protection. For radiocommunications transmitters with AAS, the LOP is -107 dBm per 30 kHz. For radiocommunications transmitters without AAS, the LOP is –115 dBm per 30 kHz,

G_r

:

is the nominal radiocommunications receiver antenna gain including feeder loss set to 0 dBi,

PL(l_mn, L_nm) :
is the propagation loss (dB) set out in Part 3 of the m^th increment on the n^th radial.

Part 3 Calculation of propagation loss

h_gr

:

is the nominal radiocommunications receiver antenna height above ground level, being 1.5 metres.

:

is the transmitter effective antenna height (in metres) as defined in Schedule 3, except:

if < 1.5 metres, then = 1.5 metres; or

if > 500 metres then = 500 metres.

d(l_mn, L_mn)

:

is the distance in kilometres between the location of the radiocommunications transmitter, (l_t, L_t), and the m^th increment on the n^th radial (l_mn, L_mn).

2. The propagation loss for the m^th increment on the n^th radial is established as follows:

Step 1: Calculate the parameters required

Step 2: Calculate the propagation loss for the m^th increment on the n^th radial

Note The formula in Step 1 and Step 2 use the Modified Hata propagation model from ERC Report 068 published by the European Conference of Postal and Telecommunications Administrations (CEPT) in 2000 and revised in 2002.

Schedule 3 Effective antenna height and average ground height

(subsection 5(1) and section 10)

Part 1 Effective antenna height of a transmitter
1.If:

(a)h_gt is the vertical height in metres of the phase centre of the fixed transmitter’s antenna measured with an error of less than 5 parts in 100 and relative to the point:

(i)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

(ii)having the lowest elevation on that line;

(b)h_s is the sum of the DEM-3S cell height at the location of the radiocommunications transmitter as (defined in Schedule 1) and h_gt; and

(c)is the average ground height of the DEM-3S cell at each m-increment on each n-radial as calculated in accordance with Part 2;

then the effective antenna height is (as shown in Diagram 1) except when is less than , in which case is .

2.For a group of radiocommunications transmitters, h_gt is the greatest of the h_gt for each individual transmitter in the group, calculated as in 1(a).

3.If the seconds component of the latitude or longitude of the radiocommunications transmitter as defined in Schedule 1, plus 1.5, has a modulus of zero when divided by 3, then h_s is the sum of:

(a) h_gt; and

(b) the maximum height of the adjacent DEM-3S cells.

Diagram 1 Calculating effective antenna height
Part 2 Average ground height

1. The average ground height for the m^th increment on the n^thradial is calculated as follows:

Step 1: determine the associated latitude and longitude of the m^th increment on the n^th radial as calculated in Part 3.

Step 2: identify the DEM-3S cell represented by the latitude and longitude of the m^th increment on the n^th 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 2).

Step 4: determine the average value of height from the 3x3 matrix.

2.If the seconds component of , plus 1.5, has a modulus of zero when divided by 3, then the corresponding DEM-3S cell, for the purposes of Step 2 in item 1, is the adjacent DEM-3S cell with the minimum height.

MP	:	is PL(l_mn,L_mn) + LOP - G_r
RP	:	is the horizontally radiated power, measured in dBm EIRP per 30 kHz, for each bearing, σ_n,
LOP	:	is the level of protection. For radiocommunications transmitters with AAS, the LOP is -107 dBm per 30 kHz. For radiocommunications transmitters without AAS, the LOP is –115 dBm per 30 kHz,
G_r	:	is the nominal radiocommunications receiver antenna gain including feeder loss set to 0 dBi,
PL(l_mn, L_nm)	:	is the propagation loss (dB) set out in Part 3 of the m^th increment on the n^th radial.

f	:	is the nominal frequency of the radiocommunications transmitter, being 1840 MHz.
h_gr	:	is the nominal radiocommunications receiver antenna height above ground level, being 1.5 metres.
:	is the transmitter effective antenna height (in metres) as defined in Schedule 3, except: if < 1.5 metres, then = 1.5 metres; or if > 500 metres then = 500 metres.
d(l_mn, L_mn)	:	is the distance in kilometres between the location of the radiocommunications transmitter, (l_t, L_t), and the m^th increment on the n^th radial (l_mn, L_mn).

l_t	:	is the latitude of the fixed transmitter (decimal radians)
L_t	:	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×500 metres)
a	:	is the semi-major axis of (6378137 metres)
f_l	:	is the flattening of (1/298.25722210)
b	:	is the semi-minor axis of (a×(1-f_l))
