                                         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.
