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.
