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 37cm away from the body of the user. So,
this device is classified as Mobile Device.

3    Calculation Result of Maximum Conducted Power

Frequency Band            Max Power   Antenna Gain             Distance    Power Density            Limit
    (MHz)                   (dBm)         (dBi)                  (cm)        (mW/cm2)             (mW/cm2)
                                                   CDD Mode

    2412-2462               29.54          9.02                  37            0.417                   1

    5180-5240               28.15          10.02                 37            0.381                   1

    5745-5825               29.65          10.02                 37            0.539                   1

                                             Beamforming Mode

    2412-2462               28.00          3.78                  37            0.088                   1

    5180-5240               26.38          5.77                  37            0.095                   1

    5745-5825               27.88          5.77                  37            0.135                   1
Note:
1. The above Max Power is tune-up power which client declared.
2. Antenna gain:
CDD Mode:
2.4GHz Band: Directional gain = 3dBi + 10log(4) = 9.02dBi
5GHz Band: Directional gain = 4dBi +10log (4) = 10.02dBi
Beamforming Mode:
2.4GHz Band: Beamforming gain = 3.78dBi
5GHz Band: Beamforming gain = 5.77dBi

Conclusion:
2.4GHz & 5GHz Band 1 or 2.4GHz & 5GHz Band 4 can transmit at same time.
The formula of calculated the MPE is:
CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1
CPD = Calculation power density
LPD = Limit of power density

1. WLAN 2.4GHz + WLAN 5GHz Band 1 = 0.417 + 0.381 = 0.798
2. WLAN 2.4GHz + WLAN 5GHz Band 4 = 0.417 + 0.539 = 0.956


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