BACKGROUND

Interference to a spectrum licensee’s registered receiver is managed 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;

• other conditions of the spectrum licences (see s.71 of the Act);

• 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 registered fixed receivers operated under 27 GHz spectrum licences and caused by transmitters operated under 28 GHz spectrum licences; and

- interference to registered fixed receivers operated under 28 GHz spectrum licences and caused by transmitters operating under 27 GHz spectrum licences.

PART 1¾INTRODUCTION

Title

1.1.  These guidelines are the Radiocommunications Advisory Guidelines (Managing Interference between 27 GHz and 28 GHz Spectrum-Licensed Services) 2000.

Commencement

1.2.  These guidelines commence on      21 September   2000.

Purpose of these guidelines

1.3.    The purpose of these advisory guidelines is to manage interference by providing for the protection of:

(a)     registered fixed receivers operating under spectrum licences issued for the 27 GHz band from interference caused by transmitters operated under 28 GHz spectrum licences; and

(b)   registered fixed receivers operating under spectrum licences issued for the 28 GHz band from interference caused by transmitters operated under 27 GHz spectrum licences.

Interpretation

1.4.  In these guidelines, unless the contrary intention appears:

Act means the Radiocommunications Act 1992.

fixed receiver means a radiocommunications receiver located at a fixed point on land or sea and not established for use while in motion.

Register means the Register established under s.143 of the Act.

s.145 determinations means the Radiocommunications (Unacceptable Levels of Interference¾27 GHz Band) Determination 2000 and the Radiocommunications (Unacceptable Levels of Interference¾28 GHz and 31 GHz Bands) Determination 1998.

27 GHz band  means the frequency band 26.5 GHz - 27.5 GHz.

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

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

(3)  A term used in these guidelines that is defined in the s.145 determination has the same meaning as in that determination.

[NOTES:  1.  The following terms, used in this determination, are defined in the Radiocommunications Act 1992 and have the meanings given to them by that Act:

frequency band,  interference,  spectrum licence,  transmitter.]

PART 2¾MANAGING INTERFERENCE FROM SPECTRUM-LICENSED SERVICES

Recording Device Details in the Register

2.1  A receiver will not be afforded protection unless details of the receiver are in the Register.

Relationship between the 27 GHz and 28 GHz Spectrum Licences

2.2  Spectrum licences in the 27 GHz band and 28 GHz band are subject to the same core conditions and other conditions in relation to the management of interference.  For registration of transmitters both licences are covered by similar s.145 determinations.  The 27 GHz spectrum licences have some additional licence conditions to protect satellite receivers that may operate in the 27 GHz band. These do not affect the relationship between spectrum licensees.

2.3  This means that interference from transmitters operated under 28 GHz spectrum licences to receivers operated in spectrum covered by a 27 GHz spectrum licence should be managed in the same way as interference from transmitters operated under other spectrum licences in the 27 GHz band.

2.4  Similarly it also means that interference from transmitters operated under 27 GHz spectrum licences to receivers operated in spectrum covered by a 28 GHz spectrum licence should be managed in the same way as interference from transmitters operated under other spectrum licences in the 28 GHz band.

2.5  This interference is managed through the licence core conditions and the s.145 determinations.
