F = Frequency in MHz


3. 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


4. 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.


5. ANTENNA GAIN

The declared antenna gain is 3.62dBi.
 this antenna gain was used for conducted spurious/bandedge calculations.

 --- END ---

CONCLUSION:
Both of the WLAN and Bluetooth 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 0.21630 / 1 + 0.00275 / 1= 0.219, which is less
than “1”. This confirmed that the device comply with FCC 1.1310 MPE limit.
