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/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 20cm away from the body of the user. So,
this device is classified as Mobile Device.



2.4     Antenna Gain

BT: Chip Antenna, -6.5dBi Gain
WCDMA: Passive Antenna, 0dBi Gain
LTE (Band 2, Band 4, Band 12): Passive Antenna, 0dBi Gain

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


If BT and LTE/WCDMA transmit simultaneously;
Bluetooth = (0.00018/1) x 100 = 0.02 %
WCDMA (Band II) = (0.0755/ 1) x 100 = 7.55 %
WCDMA (Band V) = (0.0760 / 0.549) x 100 = 13.84 %
LTE (Band II) = (0.0497 / 1) x 100 = 4.97 %
LTE (Band IV) = (0.0538 / 1) x 100 = 5.38 %
LTE (Band XII) = (0.0389 / 0.466) x 100 = 8.35 %

Total MPE Percentage (Worst case) = 0.02 + 13.84 = 13.86 %< 100%

The Above Result had shown that the Device complied with MPE requirement.
