10 Interference with other stations

(1) This instrument authorises operation of a station only when its operation does not interfere with the operation of a radiocommunications receiver. (2) For the purposes of subsection (1), the operation of a station authorised by this instrument is taken to not interfere with the operation of an area-wide receive station that is: (a) operating under an area-wide receive licence in the frequency band of 27.5 GHz to 28.1 GHz that is located outside a 26 GHz band spectrum licence area; or (b) operating under an area-wide receive licence in the frequency band of 28.1 GHz to 29.5 GHz. (3) This instrument authorises operation of a station in the frequency bands of 1610 MHz to 1626.5 MHz and 1670 MHz to 1675 MHz within 20 kilometres of a radio astronomy observatory mentioned in Australian footnote reference AUS87 of the spectrum plan, only if: (a) the operator of the station has sought advice from the operator of the radio astronomy observatory about when it may operate the station in order to minimise the risk of interference; and (b) the station is operated during periods consistently with the advice from the operator of the radio astronomy observatory.

Note: The spectrum plan is available, free of charge, from the Federal Register of Legislation at www.legislation.gov.au.

(4) The operator of a radio astronomy observatory may give advice to a person for the purposes of subsection (3).

Note: See subsection 133(3) of the Act.

(5) This instrument does not authorise operation of a station in the frequency bands of 1660 MHz to 1660.5 MHz and 1668 MHz to 1670 MHz when the station: (a) is within 500 kilometres of a radio astronomy observatory mentioned in Australian footnote reference AUS87 of the spectrum plan; or (b) is on board an aircraft that is in the air.

Note: The spectrum plan is available, free of charge, from the Federal Register of Legislation at www.legislation.gov.au.

(6) This instrument does not authorise the operation of a station in the frequency band of 1673.38 MHz to 1675 MHz if the emissions of the radiocommunications transmitter of the station exceed a level of -128.1 dBm/4 MHz for more than 20% of the time at the output of the antenna of any radiocommunications receiver authorised to operate in all or part of that frequency band under an earth receive licence. (7) Subject to subsection (8), this instrument authorises the operation of a station in the frequency band of 2005 MHz to 2010 MHz only if: (a) the radiocommunications transmitter of the station is not on board an aircraft that is in the air; and (b) the emissions of the radiocommunications transmitter above the frequency 2010 MHz do not exceed an EIRP of -66 dBW for each MHz. (8) This instrument does not authorise the operation of a station in the frequency band of 2005 MHz to 2010 MHz in a metropolitan area unless: (a) the emissions of the radiocommunications transmitter of the station do not exceed a maximum EIRP of 0.5 dBW for each MHz; and (b) the maximum duty cycle of the radiocommunications transmitter does not exceed 1% averaged over a 15-minute period; and (c) each transmission of the radiocommunications transmitter does not exceed 4 seconds in duration. (9) This instrument authorises the operation of a station in the frequency band of 27.5 GHz to 28.3 GHz on land only if the radiocommunications transmitter of the station: (a) is not operated in the frequency band of 27.5 GHz to 28.1 GHz in a 26 GHz band spectrum licence area; and (b) when operated in the frequency band of 28.1 GHz to 28.3 GHz in a 26 GHz band spectrum licence area, is not operated within the greater of:
