2 MPE EVALUATION OF MOBILE DEVICES Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since exposures are assumed to occur at distances of 20 cm or more from persons. 2.1 LIMITS FOR GENERAL POPULATION/UNCONTROLLED EXPOSURE 2 Frequency Range (MHz) Power Density (mW /cm ) Averaging Time (minutes) 300~1500 F/1500 30 1500~100000 1.0 30 2.2 MPE EVALUATION FORMULA Pt Pd = 4 * Pi * R 2 Where 2 Pd= Power density in mW/cm Pt= EIRP in mW Pi= 3.1416 R= Measurement distance 2.3 MPE EVALUATION RESULTS MPE Evaluation of Single Transmission Maximum Power Frequency Rated Power Antenna Distance Limit Conducted Density 2 Range (MHz) (dBm) Gain (dBi) (cm) 2 (mW/cm ) Power (dBm) (mW/cm ) 2402 ~ 2480 0.59 1.00 3.5 20 0.001 1 902.3 ~ 914.9 18.94 19.00 0 20 0.016 0.602 MPE Evaluation of Simultaneous Transmission MPE Evaluation = Maximum MPE of BT LE + Maximum MPE of LoRa = 0.001 / 1 + 0.016 / 0.602 = 0.028 < 1 Conclusion MPE evaluations of single and simultaneous transmission meet the requirement of standard.
