§ 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:

   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.
