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[micro]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.
