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



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.

2.5     Calculation Result of Maximum Conducted Power

For BT-LE the Maximum power was refer to the FCC test report (Report No.: RF180131E09B-2)

WLAN:
Frequency Band        Max Power         Antenna Gain           Distance   Power Density         Limit
                                                                                   2                  2

BT-LE
Frequency Band        Max. Power        Antenna Gain           Distance   Power Density         Limit
                                                                                   2                  2
    (MHz)               (mW)                (dBi)                (cm)       (mW/cm )          (mW/cm )
      2402-2480           14.322            1.91                 20         0.00442                1




Conclusion:
The formula of calculated the MPE is:
CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1
CPD = Calculation power density
LPD = Limit of power density


WLAN + Bluetooth = 0.12934 / 1 + 0.00442 / 1 = 0.13376
Therefore the maximum calculations of above situations are less than the “1” limit.
