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)

11.1 Friis transmission formula: Pd= (Pout*G)\ (4*pi*R2)
Where
Pd= Power density in mW/cm
Pout=output power to antenna in mW
G= Numeric gain of the antenna relative to isotropic antenna
Pi=3.1416
R= distance between observation point and center of the radiator in cm(20cm)
Pd the limit of MPE, 1mW/cm . If we know the maximum gain of the antenna and total power
input to the antenna, through the calculation, we will know the distance where the MPE limit is
reached.
mW=10^(dBm/10)
