RF EXPOSURE EVALUATION
According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the
environment impact of human exposure to radio frequency (RF) Radiation as specified in
§1.1307(b)

Limits for Maximum Permissible Exposure (MPE)




MPE Calculation Method

             30 * P * G                                                  E2
E (V/m) =                                 Power Density: Pd (W/m²) =
                 d                                                       377
E = Electric field (V/m)
P = Average RF output power (W)
G = EUT Antenna numeric gain (numeric)
d = Separation distance between radiator and human body (m)
The formula can be changed to

       30 * P * G
Pd =
       377 * D 2
From the EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the
gain of the used antenna, the RF power density can be obtained.
