According to subpart 15.247(i)and subpart §1.1307(b)(1), 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.

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/4πR² = 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);
