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.
