Sec.  22.352  Protection from interference.

    Public Mobile Service stations operating in accordance with 
applicable

[[Page 42]]

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).
