Limits for Maximum Permissible Exposure(MPE)

  Frequency     Electric Field Magnetic Field         Power               Average

  300-1500            --               --             F/300                  6

            (B) Limits for General Population/Uncontrol Exposures
  300-1500            --               --             F/1500                 6

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

   Where
   Pd= Power density in mW/cm2
   Pout=output power to antenna in Mw
   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, 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.
