f = Frequency in MHz; *Plane-wave equivalent power density


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.

    5745-5825               22.37                 5.01                    20      0.109                   1
Remark: The above Max power is tune-up power.

Note:
2.4GHz Band: Directional gain = 1dBi +10log(2) = 4.01dBi
5GHz Band: Directional gain = 2dBi +10log(2) = 5.01dBi

Conclusion:
The WLAN 2.4G & WLAN 5G 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

WALN 2.4GHz + WALN 5GHz = 0.141 + 0.218 = 0.359


Therefore the maximum calculations of above situations are less than the “1” limit.
