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: The Max Power = Max tune up power
2412~2462MHz Directional gain = 5.71dBi
5180~5240MHz Directional gain = 5.01dBi
5260~5320MHz Directional gain = 5.63dBi
5500~5700MHz Directional gain = 5.71dBi
5745~5825MHz Directional gain = 4.65dBi

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

1.    WLAN 2.4GHz + WLAN 5GHz band 1 + WLAN 5GHz band 3 = 0.231 + 0.133 + 0.171 = 0.535 < 1
2.    WLAN 2.4GHz + WLAN 5GHz band 1 + WLAN 5GHz band 4 = 0.231 + 0.133 + 0.357 = 0.721 < 1
3.    WLAN 2.4GHz + WLAN 5GHz band 2 + WLAN 5GHz band 3 = 0.231 + 0.158 + 0.171 = 0.560 < 1
4.    WLAN 2.4GHz + WLAN 5GHz band 2 + WLAN 5GHz band 4 = 0.231 + 0.158 + 0.357 = 0.746 < 1
