F = Frequency in MHz



2.2      MPE Calculation Formula

Pd = (Pout*G) / (4*pi*r2)
where
Pd = power density in mW/cm2
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 20cm away from the body of the user.
         So, this device is classified as Mobile Device.

NOTE:
2.4GHz: Directional gain = 5dBi + 10log(2) = 8.01dBi
5GHz: Directional gain = 6dBi + 10log(2) = 9.01dBi


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 = 0.44745 + 0.38489 = 0.832
Therefore the maximum calculations of above situations are less than the “1” limit.
