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 23cm away from the body of the user. So,
this device is classified as Mobile Device.

3    Calculation Result of Maximum Conducted Power

For 15.247 (2.4GHz) data was copied from the original test report (Report No.: SA120725E01)
  Frequency
                  Max Power      Antenna Gain         Distance       Power Density       Limit

     (MHz)
    2412-2462         575.666            7.21                    23       0.45552                1

    5180-5240          45.134            9.31                    23       0.05792                1

    5745-5825         266.159            9.79                    23       0.38148                1

NOTE:
2.4GHz: Directional gain = 2.44dBi + 10log(3) = 7.21dBi
5GHz (5150-5250MHz): Directional gain = 10 log[(10G1/20 + 10G2/20 + 10G3/20)2 / 3] = 9.31dBi
5GHz (5725-5850MHz): Directional gain = 10 log[(10G1/20 + 10G2/20 + 10G3/20)2 / 3] = 9.79dBi


Conclusion:
Both of the 2.4GHz and 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 0.45552 / 1 + 0.38148 / 1 = 0.837, which is less than “1”. This confirmed
that the device comply with FCC 1.1310 MPE limit.
