F = Frequency in MHz



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 23cm away from the body of the user.
      So, this device is classified as Mobile Device.

Radio 2(WLAN: Single Band)
  Frequency     Max Power          Antenna Gain           Distance    Power Density        Limit
                                                                               2                 2

NOTE:
2.4GHz: Directional gain = 5.9dBi
5GHz:
U_NII-1: Directional gain = 4dBi
U_NII-2A: Directional gain = 4dBi
U_NII-2C: Directional gain = 5.89dBi
U_NII-3: Directional gain = 5.89dBi


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(UNII-3) + WLAN 5GHz(UNII-1)
= 0.47693 / 1 + 0.30436 / 1 + 0.11179 / 1
= 0.89308
Therefore the maximum calculations of above situations are less than the “1” limit.
