MPE Calculation Formula
Pd = (Pout*G) / (4*pi*r )
where
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 20cm away from the body of the user.
So, this device is classified as Mobile Device.

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 + Bluetooth = 0.73608 / 1 + 0.00181 / 1 = 0.73789
WLAN 5GHz + Bluetooth = 0.25371 / 1 + 0.00181 / 1 = 0.25552
Therefore the maximum calculations of above situations are less than the “1” limit.
