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           Power      Average
Range(MHz)      Strength(V/m)       Field      Density(mW/cm2)   Time
                                Strength(A/m)
               (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.
