  RF exposure

According to FCC part 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 range           Electric field        Magnetic field          Power density
                                                                                                     Average time
       (㎒)                 strength(V/m)         strength (A/m)             (㎽/㎠)
                                  (A) Limits for Occupational / Control Exposures
    300 – 1 500                  --                     --                      f/300                     6
  1 500 - 100000                 --                     --                        5                       6
                              (B) Limits for General Population / Uncontrol Exposures
    300 – 1 500                  --                     --                      f/1500                    6
  1 500 – 100 000                --                     --                        1                      30
f= frequency in ㎒

Friis transmission formula: Pd = (Pout×G)/(4×pi×R2)
 Where,
  Pd = power density in ㎽/㎠
  Pout = output power to antenna in ㎽
  G = gain of antenna in linear scale
  Pi = 3.1416
  R = distance between observation point and center of the radiator in cm
  Pd the limit of MPE, 1 ㎽/㎠. If we know the maximum gain of the antenna and the total power
  input to the antenna, through the calculation, we will know the distance where the MPE limit is
  reached.
