the receiver.
Coordination of 900 MHz base station receivers with existing 850 MHz base station transmitters
 (7) Coordination of a new 900 MHz base station receiver with an 850 MHz base station transmitter that is already registered may occur by:
(a) applying the protection criterion above the restricted segment; and
(b) taking into account the details of the transmitter in the Register.
 (8) For the purposes of subsection (7), if information about the out-of-band emissions of the 850 MHz base station transmitter is not available, assume there is an adjacent-channel leakage ratio of at least 100 dB below the transmitter's in-channel power.
Notification of intention to register a device
 (9) A spectrum licensee (the second licensee) who intends to register a radiocommunications device (the new device) under their licensee must, before giving the ACMA details of the new device for registration on the Register, give notice of the new station to a spectrum licensee (the first licensee) where:
(a) the first licensee has already registered a radiocommunications device under a spectrum licence in the 850 MHz band or the 900 MHz band (the existing device); and
(b) either:
             (i) the new device does not meet the protection criterion; or
             (ii) the new device would be located within 800 metres of the first device.
 (10) If the second licensee gives notice under subsection (9) in relation to an 850 MHz base station transmitter intended to be registered, subject to any agreement between the first licensee and the second licensee to manage adjacent band interference:
(a) the second licensee, must ensure, by the end of the notification window, that the transmitter either:
             (i) satisfies the protection criterion; or
             (ii) has an adjacent-channel leakage ratio of at least 100 dB below the transmitter's in-channel power; and
(b) a 900 MHz band base station receiver will generally not receive protection from the registering 850 MHz transmitter unless the receiver satisfies the selectivity requirement by the end of the notification window.
Note: If paragraph 10(a) is not met, the ACMA will have regard to first-in-time status of registrations when deciding whether to enter a device on the Register, in line with its normal practice. The ACMA may also have regard to which parties have borne the costs of acting in accordance with this section when deciding on whether protection is to be afforded to a 900 MHz base station receiver.
Definitions
 (11) In this section:
       notification window, for a radiocommunications device in relation to a second radiocommunications device, means the three month period commencing on the day the spectrum licensee authorised to operate the device receives notification under subsection (9) about the second radiocommunications device.
       protection criterion means -102dBm/(5MHz) in any 5 MHz block of
