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)

11.1 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=3.1416
R= distance between observation point and center of the radiator in cm
Pd the limit of MPE, 1mW/cm2. If we know the maximum gain of the nd total
power input to the antenna, through the calculation, we will know the distance
where the MPE limit is reached.
