§ 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
(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
(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.
