    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.
