BACKGROUND

 

A spectrum licence covers a frequency band and a geographic area.  Interference occurring between devices operating under adjacent spectrum licences consists of:

·      in-band interference, across the geographic boundaries; and

·      out-of band interference, across the frequency boundaries.

This interference is managed by creating emission buffer zones along the geographic and frequency boundaries of the licence, using a number of tools provided by the Radiocommunications Act 1992.  These tools are:

·      the core conditions in all spectrum licences (see s.66 of the Act), about:

          - emission limits outside the area; and

          - emission limits outside the band;

·      the determination under s.145 of the Act about what constitutes unacceptable interference;

·      advisory guidelines made under s.262 of the Act, about managing interference in specific circumstances.

The following advisory guidelines under s.262 of the Act have been made for the management and settlement of interference to receivers operating otherwise than under spectrum licences in the 28 GHz and 31 GHz bands, caused by spectrum-licensed transmitters.

 

 

PART 1¾INTRODUCTION

 

Title

          1.1.  These guidelines are called the Radiocommunications Advisory Guidelines (Protection of Non-spectrum-licensed Receivers¾28 GHz and 31 GHz Bands) 1998.

 

 

Commencement

          1.2.  These guidelines commence on  11 November        1998.

 

 

Purpose of these guidelines

          1.3. (1)  The purpose of these guidelines is to provide information on the protection requirements for non-spectrum-licensed receivers from spectrum-licensed transmitters operating in the 28 GHz (27.5 to 28.35 GHz) and 31 GHz (31 to 31.3 GHz) bands. 

 

          (2)  These guidelines are separated into two parts.  The first part addresses the protection requirements for non-spectrum licensed receivers in and adjacent to the 28 GHz band.  The second part addresses the protection requirements for non-spectrum licensed receivers in and adjacent to the 31 GHz band.


 

Principles of protection requirements

          1.4  There is little technical information available on the protection requirements for services identified in this guideline because the services are not yet fully developed.  When developed, the protection requirements are likely to relate to:

·      maximum aggregate interference power spectral density levels;

·      maximum equivalent isotropically radiated power density levels;

·      protection ratios (co-channel, adjacent channel and image channel).

 

 

Interpretation

          1.5 (1)   In these guidelines, unless the contrary intention appears:

 

Act means the Radiocommunications Act 1992.

 

Australian Radiofrequency Spectrum Plan means the Spectrum Plan made by the Spectrum Management Agency (now the ACA) on 19 December 1996, copies of which are available from the ACA.

 

non-spectrum licensed, in relation to a receiver or a service, means a receiver or service operated in spectrum space by a person:

          (a) who does not hold a spectrum licence for that space; or

          (b) who is not authorised under section 68 of the Act to operate

radiocommunications in that space.

 

RALI FX3  means the Radiocommunications Assignment and Licensing Instruction No. FX3 issued by the ACA, as in force from time to time, copies of which are available from the ACA.

 

28 GHz band means the frequency band 27.5 GHz - 28.35 GHz.

 

31 GHz band means the frequency band 31 GHz - 31.3 GHz.

 

          (2)  A term used in these Guidelines that is defined in the Australian Radiofrequency Spectrum Plan has the same meaning as in that Plan.

 

          (3)  In these guidelines, the range of numbers that identifies a frequency band includes the higher, but not the lower, number.

[Notes:

1.          A number of expressions used in these Guidelines are defined in the Act, including:

apparatus licence

spectrum licence.

2.          The following expressions used in these Guidelines are defined in the Australian Radiofrequency Spectrum Plan:

earth exploration-satellite service

fixed service

fixed-satellite service

mobile-satellite service

inter-satellite service

radioastronomy

mobile service

space research service]

 

PART 2¾NON-SPECTRUM LICENSED RECEIVERS IN AND ADJACENT TO THE 28 GHz BAND

 

2.       Fixed Service Receivers

 

Background

          2.1  In the Australian Radiofrequency Spectrum Plan there are primary allocations to the fixed service in the 27 to 27.5 GHz band and 28.35 to 29.1 GHz band.  These bands are adjacent to the 28 GHz spectrum licensed band.  At the time of preparation of this Advisory Guideline there were no known fixed services operating in these bands in Australia and protection requirements have not yet been developed.  However, fixed services may operate in these bands in the future. 

 

It is the ACA’s practice to develop protection requirements in consultation with industry.  The requirements are usually based on internationally accepted ITU Recommendations.

 

Protection Requirements

          2.2  In planning for the operation of transmitters under a spectrum licence, spectrum licensees should pay regard to the protection requirements, when specified by the ACA, for receivers of any non-spectrum licensed fixed services that are operating in the 27 to 27.5 GHz band and 28.35 to 29.1 GHz band. 

 

 

3.       Fixed-Satellite Service Receivers

 

Background

          3.1  In the Australian Radiofrequency Spectrum Plan there are primary allocations to the fixed-satellite (Earth-to-space) service in the 27 to 29.1 GHz band.  This band overlaps the 28 GHz spectrum licensed band.  At the time of preparation of this Advisory Guideline there were no known satellite receivers in the fixed-satellite (Earth-to-space) services operating in this band and protection requirements have not yet been developed.  However, global fixed-satellite services may operate in this band in the future.

 

Protection requirements for satellite receivers in the fixed-satellite (Earth-to-space) service are usually developed by the ITU and specified in ITU Recommendations.

 

 

Protection Requirements

          3.2  In planning for the operation of transmitters under a spectrum licence, spectrum licensees should pay regard to the protection requirements specified in ITU

Recommendations, when they have been prepared by the ITU, for satellite receivers of any non-spectrum licensed fixed-satellite (Earth-to-space) services that are operating in the 27 to 29.1 GHz band.

 


4.       Inter-Satellite Service Receivers

 

Background

          4.1  In the Australian Radiofrequency Spectrum Plan there are primary allocations to the inter-satellite service in the 27 to 27.5 GHz band.  This band is adjacent to the 28 GHz spectrum licensed band.  A number of space agencies are planning to operate inter-satellite services in this band in the future.

 

Protection Requirements

          4.2  In planning for the operation of transmitters under a spectrum licence, spectrum licensees should pay regard to all protection requirements specified by the ITU for the inter-satellite service.  Some protection requirements are set out in the following ITU Recommendations:

·      ITU-R SA.609:  Protection Criteria for Telecommunication Links for Manned and Unmanned near-Earth Research Satellites.

·      ITU-R SA.1155:  Protection Criteria Related to the Operation of Data Relay Satellite Systems.

 

Additional ITU Recommendations relevant to the protection requirements for the inter-satellite service are currently being developed by the ITU.

 

 

5.       Mobile Service Receivers

 

Background

          5.1  In the Australian Radiofrequency Spectrum Plan there are primary allocations to the mobile service in the 27 to 27.5 GHz band and 28.35 to 29.1 GHz band.  These bands are adjacent to the 28 GHz spectrum licensed band.  At the time of preparation of this Advisory Guideline there were no known mobile services operating in these bands in Australia and protection requirements have not yet been developed. However, mobile services may operate in these bands in the future.

 

It is the ACA’s practice to develop protection requirements in consultation with industry.  The requirements are usually based on internationally accepted ITU Recommendations.

 

Protection Requirements

          5.2  In planning for the operation of transmitters under a spectrum licence, spectrum licensees should pay regard to the protection requirements, when specified by the ACA, for receivers of any non-spectrum licensed mobile services that are operating in the 27 to 27.5 GHz band and 28.35 to 29.1 GHz band. 

 


PART 3¾NON-SPECTRUM LICENSED RECEIVERS IN AND ADJACENT TO THE 31 GHz BAND

 

 

6.       Earth Exploration-Satellite (passive)

 

Background

          6.1.  In the Australian Radiofrequency Spectrum Plan there are primary allocations to the earth exploration-satellite (passive) service in the 31.3 to 31.8 GHz band.  This band is adjacent to the 31 GHz spectrum licensed band.  At the time of preparation of this Advisory Guideline there were no known earth exploration-satellite (passive) services operating in that band and protection requirements have not yet been developed.  However, earth exploration-satellite (passive) services may operate in this band in the future.

 

Protection requirements for the earth exploration-satellite (passive) service are usually developed by the ITU and specified in ITU Recommendations.

 

Protection Requirements

          6.2  In planning for the operation of transmitters under a spectrum licence, spectrum licensees should pay regard to the protection requirements specified in ITU Recommendations, when they have been prepared by the ITU, for receivers of any non-spectrum licensed earth exploration-satellite (passive) services that are operating in the 31.3 to 31.8 GHz band.

 

 

7.       Fixed-Satellite and Mobile-Satellite Services Receivers

 

Background

          7.1  In the Australian Radiofrequency Spectrum Plan there are primary allocations to fixed-satellite (Earth-to-space) and mobile-satellite (Earth-to-space) services in the 30 to 31 GHz band.  This band is adjacent to the 31 GHz spectrum licensed band.  At the time of preparation of this Advisory Guideline there were no known satellite receivers in the fixed-satellite (Earth-to-space) and mobile-satellite (Earth-to-space) services operating in this band in Australia and protection requirements have not yet been developed.  However, the Department of Defence has advised that it is planning to operate fixed-satellite and mobile-satellite services in this band.

 

Protection requirements for satellite receivers in the fixed-satellite (Earth-to-space) and mobile-satellite (Earth-to-space) services are usually developed by the ITU and specified in ITU Recommendations.

 

Protection Requirements

          7.2.  In planning for the operation of transmitters under a spectrum licence, spectrum licensees should pay regard to the protection requirements specified in ITU Recommendations, when they have been prepared by the ITU, for satellite receivers of any non-spectrum licensed fixed-satellite (Earth-to-space) and mobile-satellite (Earth-to-space) services that are operating in the 30 to 31 GHz band.

 

 

8.       Fixed Point to Point Receivers

 

Background

          8.1.  The 31 GHz fixed service operates in the 31 to 31.3 GHz band which is subject to spectrum licensing.  There are several incumbent point-to-point receivers for the fixed service in this band in Australia.  The detail of these incumbents can be obtained from the ACA.

 

Incumbent fixed receivers will require protection for the reallocation period specified in the declaration for the 31 GHz band.

 

Protection Requirements

          8.2.  The protection requirements for 31 GHz fixed receivers are specified in the 31 GHz section of RALI FX3.  In planning for the operation of transmitters under a spectrum licence, spectrum licensees should pay regard to those protection requirements.

[NOTE:  For more information on the 31 GHz fixed service see the 31 GHz section of RALI FX3]

 

 

9.  Radioastronomy

 

Background

          9.1.  In the Australian Radiofrequency Spectrum Plan there are primary allocations to the radioastronomy service in the 31.3 to 31.8 GHz band.  This band is adjacent to the 31 GHz spectrum licensed band.  The Australian Telescope National Facility has advised that radioastronomy observations may be made in the 31.3 to 31.8 GHz band at the following observatories:

·      the Paul Wild Observatory Narrabri NSW (latitude 30°59'52.048"S, longitude 149°32'56.327"E);
