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: 1. Determining compliance based on the results of the compliance measurement, not taking into account
measurement instrumentation uncertainty.

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 = 0.019/1 + 0.009/1 = 0.028
Therefore the maximum calculations of above situations are less than the "1" limit.
