Sec. 27.64  Protection from interference.



    Wireless Communications Service (WCS) stations operating in full 

accordance with applicable FCC rules and the terms and conditions of 

their authorizations are normally considered to be non-interfering. If 

the FCC determines, however, that interference which significantly 

interrupts or degrades a radio service is being caused, it may, after 

notice and an opportunity for a hearing, require modifications to any 

WCS station as necessary to eliminate such interference.

    (a) Failure to operate as authorized. Any licensee causing 

interference to the service of other stations by failing to operate its 

station in full accordance with its authorization and applicable FCC 

rules shall discontinue all transmissions, except those necessary for 

the immediate safety of life or property, until it can bring its station 

into full compliance with the authorization and rules.

    (b) Intermodulation interference. Licensees should attempt to 

resolve such interference by technical means.

    (c) Situations in which no protection is afforded. Except as 

provided elsewhere in this part, no protection from interference is 

afforded in the following situations:

    (1) Interference to base receivers from base or fixed transmitters. 

Licensees should attempt to resolve such interference by technical means 

or operating arrangements.

    (2) Interference to mobile receivers from mobile transmitters. No 

protection is provided against mobile-to-mobile interference.

    (3) Interference to base receivers from mobile transmitters. No 

protection is provided against mobile-to-base interference.

    (4) Interference to fixed stations. Licensees should attempt to 

resolve such interference by technical means or operating arrangements.

    (5) Anomalous or infrequent propagation modes. No protection is 

provided against interference caused by tropospheric and ionospheric 

propagation of signals.
