F = Frequency in MHz



2.2     MPE Calculation Formula

                          2
Pd = (Pout*G) / (4*pi*r )
where
                                   2
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:
Both of the Bluetooth and WLAN (5GHz) can transmit simultaneously, the formula of calculated the MPE is:


CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1
CPD = Calculation power density
LPD = Limit of power density


Therefore, the worst-case situation is 0.13389 / 1 + 0.00914 / 1 = 0.143, which is less than “1”.
