Sec.  22.352   Protection from interference.

   

   Link to an amendment published at  70 FR 19308 , Apr. 13, 2005.

   Public  Mobile Service stations operating in accordance with FCC rules
   that  provide  technical  channel  assignment  criteria  for the radio
   service and channels involved, all other 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).
