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.

Note;

— The power density Pd (5th column) at a distance of 20 en calculated from the friis transmission
   formula is far below the limit of 1. ti/en‘.
= This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
= This equipment should be installed and operated with minimum 20 cm between the radiator and your
   body.
— The antenna gain of this transmitter is less than 6dBi and must not be collocated or operating in conjunction
  with any other antenna or transmitter unless authorized to do so by the FCC.
