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



Friis transmission formula: Pd= (Pout*G)\ (4*pi*R2)
Where

Pd= Power density in mW/cm2

Pout=output power to antenna in mW

G= Numeric gain of the antenna relative to isotropic antenna

Pi=3.14115926

R= distance between observation point and center of the radiator in cm(20cm)

Pd the limit of MPE, 1mW/cm2. 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.
