Sec.  22.353   Blanketing interference.

   

   Licensees  of  Public  Mobile  Services  stations  are responsible for
   resolving  cases  of  blanketing  interference  in accordance with the
   provisions of this section.

   (a)  Except  as  provided  in paragraph (c) of this section, licensees
   must  resolve  any  cases  of blanketing interference in their area of
   responsibility  caused  by  operation of their transmitter(s) during a
   one-year period following commencement of service from new or modified
   transmitter(s).  Interference  must be resolved promptly at no cost to
   the complainant.

   (b)  The area of responsibility is that area in the immediate vicinity
   of  the  transmitting  antenna of stations where the field strength of
   the electromagnetic radiation from such stations equals or exceeds 115
   dBµV/m. To determine the radial distance to the boundary of this area,
   the following formula must be used:
   [MATH:  :MATH]

   where d is the radial distance to the boundary, in kilometers

   p is the radial effective radiated power, in kilowatts

   The  maximum  effective  radiated  power  in  the pertinent direction,
   without  consideration  of the antenna's vertical radiation pattern or
   height, must be used in the formula.

   (c)  Licensees  are not required to resolve blanketing interference to
   mobile   receivers   or  non-RF  devices  or  blanketing  interference
   occurring  as  a  result  of  malfunctioning  or  mistuned  receivers,
   improperly installed consumer antenna systems, or the use of high gain
   antennas or antenna booster amplifiers by consumers.

   (d)  Licensees  that install transmitting antennas at a location where
   there  are  already  one or more transmitting antennas are responsible
   for  resolving  any new cases of blanketing interference in accordance
   with this section.

   (e)  Two  or  more  licensees  that  concurrently install transmitting
   antennas  at  the  same location are jointly responsible for resolving
   blanketing  interference  cases,  unless the FCC can readily determine
   which  station is causing the interference, in which case the licensee
   of that station is held fully responsible.

   (f)  After the one year period of responsibility to resolve blanketing
   interference,   licensees   must   provide   upon   request  technical
   information to complainants on remedies for blanketing interference.
