            Subpart C_Operational and Technical Requirements

 

Sec. 22.352  Protection from interference.



    Public Mobile Service stations operating in 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 that significantly interrupts or 

degrades a radio service is being caused, it may, in accordance with the 

provisions of sections 303(f) and 316 of the Communications Act of 1934, 

as amended, (47 U.S.C. 303(f), 316), require modifications to any Public 

Mobile 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) Inteference 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.

    (6) Facilities for which the Commission is not notified. No 

protection is provided against interference to the service of any 

additional or modified transmitter operating pursuant to Sec. Sec. 

1.929 or 22.165, unless and until the licensee modifies its 

authorization using FCC Form 601.

    (7) In-building radiation systems. No protection is provided against 

interference to the service of in-building radiation systems (see Sec. 

22.383).
