The Commission's rules require private land mobile radio station
licensees to take ``reasonable precautions to avoid causing harmful
interference. This includes monitoring the transmitting frequency for
communications in progress and such other measures as may be necessary
to minimize the potential for causing interference.'' 47 C.F.R.§
The Enforcement Bureau's
Spectrum Enforcement Division,
in conjunction with the
Regional and Field Offices,
is responsible for
responding to interference complaints involving private land mobile
To ensure faster processing of such complaints, the Commission has
entered into a number of Memoranda of Understanding with certain
FCC-certified frequency advisory committees (``FACs'') or frequency
coordinators pursuant to which frequency coordinators will receive,
investigate and, if possible, resolve private land mobile interference
complaints in the first instance. Complaints that cannot be resolved
after a specified time period will be referred to the Enforcement
The Commission has entered into a Memorandum of Understanding with
three FACs: (1) Industrial Telecommunications Association, Inc.
now known as Enterprise Wireless Alliance (``EWA''), (2) Association of Public Safety Communications Officials
(``APCO'') (for interference complaints involving public safety radio
service frequencies); and (3) Association of American Railroads
(``AAR'') (for interference complaints involving communication
frequencies which formerly comprised the ``Railroad Radio Service'').
The Enforcement Bureau encourages Private Land Mobile Radio Station
licensees wishing to file interference complaints involving private
land mobile radio operations to submit such complaints directly to the
appropriate FAC in accordance with the process set forth in the
relevant Memorandum of Understanding.
In addition, the Enforcement Bureau encourages other FACs to enter into
similar Memoranda of Understanding.
