16  Spectrum licensed transmitters near the 900 MHz band
Background
 (1) Spectrum licensed base station radiocommunications receivers that are operated in the 900 MHz band use near-or-adjacent frequencies to base station radiocommunications transmitters operated under spectrum licences in the 850 MHz band.
 (2) Despite anything else in this section, negotiation between spectrum licensees is the preferred method to optimise spectrum utility and access either side of 890 MHz.
Coordination of 900 MHz base station receivers with 850 MHz base station transmitters
 (3) Base station radiocommunications receivers operated under a spectrum licence in the 900 MHz band (900 MHz base station receivers) will generally only be given protection from registered base station radiocommunications transmitters operated under a spectrum licence in the 850 MHz band (850 MHz base station transmitters) in the circumstances set out in either subsection (4) or subsection (5), and not in the circumstances set out in subsection (6).
 (4) A 900 MHz base station receiver will generally be given protection from an 850 MHz base station transmitter:
(a) where the 900 MHz base station receiver is operated above the restricted segment; and
(b) in relation to unwanted signal levels from the 850 MHz base station transmitter exceeding the protection criterion; and
(c) where the 900 MHz base station receiver satisfies the selectivity requirement.
 (5) A 900 MHz base station receiver will generally be given protection from an 850 MHz base station transmitter:
(a) where the 900 MHz base station receiver was registered before the 850 MHz base station transmitter; and
(b) either:
             (i) the licensee of the spectrum licence that authorises operation of the 850 MHz base station transmitter has not given notice to the licensee of the spectrum licence that authorises operation of the 900 MHz base station receiver in accordance with subsection (9); or
             (ii) otherwise – during the notification window for the receiver in relation to the transmitter.
 (6) A 900 MHz base station receiver will generally not be given protection from an 850 MHz base station transmitter:
(a) where the 850 MHz base station transmitter was registered before the 900 MHz base station receiver; and
(b) either:
             (i) the licensee of the spectrum licence that authorises operation of the 900 MHz base station receiver has not given notice to the licensee of the spectrum licence that authorises operation of the 850 MHz base station transmitter in accordance with subsection (9); or
             (ii) otherwise – during the notification window for the transmitter in relation to 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:
