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)

 Frequency         Electric Field     Magnetic Field        Power      Average Time
 Range(MHz)        Strength(V/m)      Strength(A/m) Density(mW/cm2)
                      (A) Limits for Occupational/Control Exposures
  300-1500                --                --              F/300            6
 1500-100000              --                --                5              6
                 (B) Limits for General Population/Uncontrol Exposures
  300-1500                --                --             F/1500            6
 1500-100000              --                --                1             30


    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.
