2     RF Exposure
2.1 Limits for Maximum Permissible Exposure (MPE)
    Frequency Range          Electric Field     Magnetic Field       Power Density         Average Time
         (MHz)              Strength (V/m)      Strength (A/m)         (mW/cm2)              (minutes)
                             Limits For General Population / Uncontrolled Exposure

       300-1500                   …                    …                  F/1500                  30

     1500-100,000                 …                    …                   1.0                    30
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.

       5745-5825               24.91             7.73             20              0.365                1
                                                  BT EDR

* The WLAN 2.4GHz can transmit with WLAN 5GHz at the same time except BT.

Note:
WLAN 2.4GHz: Directional gain = 2.59dBi + 10log(2)=5.60dBi
WLAN 5GHz: Directional gain = 4.72dBi + 10log(2)=7.73dBi
BT EDR: Antenna gain = 1.75dBi

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 + WLAN 5GHz = 0.163 + 0.365 = 0.528 < 1

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