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 34cm away from the body of the user. So,
this device is classified as Mobile Device.

Note:
1. The Max. Power = Max. tune up power including tolerance.
2. 2.4GHz (4TX): The directional gain = 5.43dBi
   2.4GHz (2TX): The directional gain = 6.33dBi
   2.4GHz (1TX); The max. gain = 5.54dBi
  5GHz:
  U—NII—1   (8TX     : The directional gain = 9.29dBi
  U—NIl—1   (4TX     : The directional gain = 10.73dBi
  U—Nil—1   (2TX     : The directional gain = 8.47dBi
  U—Nil—1   ( (1TX   : The max. gain = 6.20Bi
  U—NII—2A     (8TX): The directional gain = 9.34dBi

  U—NII—2C C (4TX): The directional gain = 10.33dBi
  U—NII—2C (2TX): The directional gain = 8.16dBi
  U—NII—2C (1TX): The max. gain = 5.8dBi
  U—NII—3 (8TX): The directional gain = 9.2dBi
  U—NII—3 (4TX): The directional gain = 10.68dBi
  U—NII—3 (2TX): The directional gain = 8.590Bi
  U—NIl—3 (1TX): The max. gain = 6.390Bi


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 + Bluetooth = 0.20779 / 1 + 0.72653 / 1 + 0.00071 /1 = 0.93503
Therefore the maximum calculations of above situations are less than the "1" limit.
