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 dB[mu]V/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.
