f = Frequency in MHz ; *Plane-wave equivalent power density



2.2      MPE Calculation Formula

                          2
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



2.3      Classification

      The antenna of this product, under normal use condition, is at least 32cm away from the body of the user.
         So, this device is classified as Mobile Device.

2.4GHz: Directional gain =10 log[(10        + 10       + 10      ) / 3] = 8.62dBi
5 GHz:
                                      G0/20     G1/20      G2/20      G3/20 2
UNII-1: Directional gain = 10 log[(10       + 10      + 10       + 10      ) / 4] = 10.71dBi
                                      G0/20     G1/20      G2/20      G3/20 2
UNII-3: Directional gain = 10 log[(10       + 10      + 10       + 10      ) / 4] = 10.55dBi



Conclusion:
The formula of calculated the MPE is:
CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1
CPD = Calculation power density
LPD = Limit of power density


WLAN 2.4GHz + WLAN 5GHz = 0.23168 / 1 + 0.63137 / 1 = 0.86305
Therefore the maximum calculations of above situations are less than the “1” limit.
