FCC §15.247 (i) & §1.1310 & §2.1091- MAXIMUM PERMISSIBLE
EXPOSURE (MPE)
Applicable Standard
According to§15.247(i) and §1.1310, systems operating under the provisions of this section shall be
operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess
of the Commission’s guidelines.

Limits for Maximum Permissible Exposure (MPE) (§1.1310, §2.1091)

f = frequency in MHz; * = Plane-wave equivalent power density;

According to §1.1310 and §2.1091 RF exposure is calculated.


Calculated Formulary:

Predication of MPE limit at a given distance
S = PG/4R² = power density (in appropriate units, e.g. mW/cm2);
P = power input to the antenna (in appropriate units, e.g., mW);
G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain
factor, is normally numeric gain;
R = distance to the center of radiation of the antenna (appropriate units, e.g., cm);
