2.1.1. Friis transmission formula: Pd = (Pout*G)/(4*pi*R‘)
    Where Pd = power density in mW/er‘
           Pout = output power to antenna in 1i
           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 iier. 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.
