MPE Calculation
For : RFID Printer, Model: 9855HF
FCCID : GU6-RFID-HF

RF Exposure Requirement : 47 CFR 1.1307(b)
RF Radiation Exposure Limit : 47 CFR 1.1310
RF Radiation Exposure Guideline : FCC OST/OET Bullentin Number 65

EUT Frequnecyt Band : 13.56 MHz
EUT Measured Output power or EIRP : 15.3 dBuV/m (Field strength @ 3 meter)
0.000000008 Watts
Eut Antenna Gain : -27.8 dBi
Distance from Antenna to Human Body: 20 cm

Limit for General Population / Uncontrolled Exposure :
=180 / f**2 (MHz) ==> 0.978933 mW/cm2 or
9.789334 W/m2

Power density Calculation : = P*G/ (4 * 3.141 * R**2)
Where, S= power density
P = Power inoput to Antenna
G = Antenna Gain
R = distance to the center of radiated antenna

EUT Power density = 2.64181E-08 W/m2

The EUT Complied with 20cm distance exposure.
