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



2.2      MPE Calculation Formula

Pd = (Pout*G) / (4*pi*r2)
where
Pd = power density in mW/cm 2
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.

2.4     Calculation Result

The Stand-alone radio module will co-locate with one Bluetooth module. This report is prepared for transmit
simultaneously condition.

       LTE B4          1720        171.791             3            20           0.06819               1

Note: *Limit of Power Density = F/1500

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


Bluetooth + LTE Band12 = 0.00256 / 1 + 0.05698 / 0.4757 = 0.12235
Therefore the maximum calculations of above situations are less than the “1” limit.


--- END ---



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


LTE Band12 + Bluetooth = 0.05926 / 0.4665 + 0.00256 / 1 = 0.12960
Therefore the maximum calculations of above situations are less than the “1” limit.
