EVALUATION METHOD
                                                   2
Transmission formula: Pd = (Pout*G)/(4*pi*r )
Where
                                2
Pd = power density in mW/cm , 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

Note:
 1) Antenna gain of ANT1 = Antenna gain of ANT2= 3dBi, Antenna gain of ANT1 + ANT2=3dBi + 10log(2) = 6dBi.
 2) The exposure safety distance is 20cm.
