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.

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



Simultaneously transmission condition.
   Condition                                              Technology
       1                      WLAN 2.4GHz                                      Zigbee
       2                        Bluetooth                                      Zigbee

WLAN 2.4GHz + Zigbee = 0.12964 / 1 + 0.03271 / 1 = 0.16235
Bluetooth + Zigbee = 0.00532 / 1 + 0.03271 / 1 = 0.03803
Therefore the maximum calculations of above situations are less than the “1” limit.
