 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.
