Maximum Permissible Exposure (MPE) Limitations
The installer must mount all transmit antennas so as to comply with the limits for human exposure to
radio frequency (RF) fields per paragraph 1.1307 of the FCC Regulations . The FCC requirements
incorporate limits for Maximum Permissible Exposure (MPE) in terms of electric field strength,
magnetic field strength, and power density.
Antenna installations must be engineered so that MPE is limited to f/1500 mW/ cm
2
(at 900 MHz) or
1 mW/cm
2
, (2.4 GHz) the more stringent limit for "uncontrolled environments". The table below
specifies the minimum distance that must be maintained between the antenna and any areas where
persons may have access, including rooftop walkways, sidewalks, as well as through windows and
other RF-transparent areas behind which persons may be located.

NOTE: For fixed location transmitters, the minimum separation

mobile transmitters the minimum is 20 or 25 cm (shown on the tables)
