Minimum path length / 20 km
Antenna requirements / refer to Appendix 11
THE 1.8 GHz BAND (1700–1900 MHz)
Note:
1.Some channels are not available for assignment (Assignment Restrictions1).
2.Proposed fixed link assignments must be coordinated with spectrum licences operating in 1.8GHz PCS and 2GHz 3G bands (Assignment Restrictions2 and refs.3, 4, 7 & 8).
3.Note potential for interference to/fromfixed services operating in the upper band channelsof the 1.8 GHz band to/from adjacent 2.1GHz band fixed services.
4.Note potential for interference to adjacent Met-Sat services near 1.7GHz from channel1 of the 14 MHz channel raster and channels 1 and 2 of the 7 MHz channel raster.
5.New and existing apparatus licensed assignments in all areas and with emissions in the frequency ranges 1710–1880MHz shall be endorsed with Advisory NoteBL, but see also notes 6 and7 (ref.10).
6.New assignments of all types and in all areas and with emissions in the frequency range 1785–1805MHz are embargoed (ref.9).
7.New apparatus licensed assignments in certain spectrum licensed areas and with emissions in the frequency ranges 1710–1785MHz and 1805–1880MHz are embargoed (ref.5).
8.Prospective new apparatus licensed assignments within specified zones around specified radio astronomy facilities and with emission bandwidths in the frequency range 1250–1780MHz must be notified to CSIRO (ref. 11).
9.The 7 MHz channel raster is to support migration of existing assignments with an emission bandwidth of 7 MHz from the 14 MHz to 7MHz raster. No other services are to be assigned on these channels.

THE 1.8 GHz BAND (1700–1900 MHz)
ASSIGNMENT RESTRICTIONS
- Channels that may NOT be assigned.
1.11.9 GHz Band Plan Provisions of the 1.9GHz Band Plan (ref. 2) which introduced the cordless telecommunications service (CTS) in the band 1880–1900MHz do not permit additional (new or re-tuned) point-to-point fixed stations in this band.
No point-to-point assignments are to be made Australia wide on the following 1.8GHz band channels:
14 MHz channel raster:
1874.5 MHz (4M') (may be available in some areas if the occupied bandwidth (BW) < 11MHz);
1881.5 MHz (4I');
1888.5 MHz (5M');
1895.5 MHz (5I'); and
1902.5 MHz (6M') (may be available in some areas if the BW < 5MHz).
7 MHz channel raster:
1881.5 MHz (8M’);
1888.5 MHz (9M');
1895.5 MHz (10M’); and
1902.5 MHz (11M') (may be available in some areas if the BW < 5MHz).
1.2Spectrum Licences Apparatus licensing is not permitted in spectrum licensed bands and areas, refer RALI MS 3 Embargo 26 (ref. 5). Therefore, no new assignments are to be made in certain areas in the 1.8GHz PCS bands (1710 to 1785MHz and 1805 to 1880MHz) and the 3G bands (1900 to 1980MHz) due to spectrum licensing (refs. 3, 4, 7 & 8).
1.3Affected Channels See Tables 1 and 2 for details on affected channels.
- Coordination requirements with PCS and 3G spectrum licenses.
Proposed fixed link assignments must be coordinated with spectrum licences operating in the 1.8GHz PCS (1710 - 1785MHz and 1805 - 1880MHz) and 3G bands (1900 - 1980MHz) in accordance with Appendix 7 of this RALI. Proposed fixed link assignments planned for co-channel operation with respect to spectrum licences in areas adjacent to spectrum licensed areas must be coordinated with spectrum licences if they are within a threshold distance of 200km of the spectrum licence boundary. Proposed fixed link assignments planned for adjacent channel operation with respect to spectrum licences inside or adjacent to spectrum licence boundaries must also be coordinated. The map at page 8 illustrates the geographic boundaries and coordination threshold contours for these coordination requirements for the 1.8GHz PCS spectrum licenses. A similar map for the 3G spectrum licenses is provided at Figure 1 of the 2.1GHz channelling arrangements. Tables 1 and 2 detail the affected channels.
Note: The terms ‘remote, ‘regional’ and ‘major city’ are used to describe areas in the context of 1.8GHz spectrum licensing. Areas defined in the Spectrum Re-allocation Declarations No. 3 of 1997 (ref. 3) for Adelaide, Brisbane, Melbourne, Perth and Sydney constitute ‘major city’ areas. The areas defined in Spectrum Re-allocation Declarations No. 4 of 1997 (ref. 4) are referred to as ‘regional’ areas, and the remainder of Australia is referred to as ‘remote’. See also the map at page 9.
THE 1.8 GHz BAND (1700–1900 MHz)
- Coordination requirements with CTS.
The operation of private CTS devices in the 1.9GHz band are authorised by the Radiocommunications (Cordless Telecommunications Devices) Class Licence 2001(ref. 6). Under the class licensing arrangements, CTS devices are not coordinated with other services, as such,existing fixedservices in this band are not protected from CTS transmitter interference.
- Coordination with existing fixed link assignments.
In addition to the coordination requirements stated above, proposed new assignments must be coordinated with existing fixed link assignments in this band and the 2.1GHz band in accordance with normal FX-3 assignment procedures.
- Channels available for assignment.
See Tables 2 and 3 for channels available for assignment.
- Non-standard channelling.
Due to the number of restrictions placed on the 1.8GHz band for fixed services the use of non-standard channel pairing is permitted. The use of non-standard channel centre frequencies will also be permitted where this will lead to improved spectrum productivity.
