11 Protection requirements – fixed-satellite service earth receive stations under earth receive licences in 3400 MHz to 3600 MHz
(1) Section 12 of the spectrum plan provides that: (a) a secondary service in a frequency band is not to cause harmful interference to a primary service in that band; and (b) a secondary service in a frequency band is not entitled to protection from harmful interference caused by a primary service in that band. (2) A 3.4 GHz transmitter operated in accordance with the conditions of a 3.4 GHz spectrum licence is taken not to cause unacceptable interference to a fixed-satellite service earth receive station operating in the 3400 MHz to 3600 MHz frequency band. (3) A 3.4 GHz spectrum licensee, in planning for the operation of a fixed transmitter under the licence, is to notify the licensee of an earth receive licence that authorises the operation of fixed-satellite service earth receive station (the affected licensee) before registering the transmitter, if frequency coordination indicates that interference may occur. Such notification will allow the affected licensee to implement mitigation measures, implement alternative arrangements for the delivery of services, or negotiate with the 3.4 GHz spectrum licensee in relation to the continued delivery of services.
Note: Where practical, 3.4 GHz spectrum licensees are encouraged to work with affected licensees to resolve any interference.
