FCC §15.247 (i) & §1.1307 (b) (1) & §2.1091- MAXIMUM PERMISSIBLE
EXPOSURE (MPE)
Applicable Standard
According to subpart 15.247 (i) and subpart 1.1307 (b)(1), 2.1091 systems operating under the provisions
of this section shall be operated in a manner that ensures the public is not exposed to RF energy level in
excess of the communication guidelines.

S = 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)
