1 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. 1.1 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 1.2 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 1.3 DEVIATION FROM TEST STANDARD AND MEASUREMENT PROCEDURE None 1.4 MEASUREMENT UNCERTAINTY ISO/IEC 17025 requires that an estimate of the measurement uncertainties associated with the emissions test results be included in the report. The measurement uncertainties given below are based on a 95% confidence level (based on a coverage factor (k=2) Parameters Uncertainty Conducted power ±0.808 dB Declaration of Conformity: The test results with all measurement uncertainty excluded are presented in accordance with the regulation limits or requirements declared by manufacturers. Comments and Explanations: The declared of product specification for EUT presented in the report are provided by the manufacturer, and the manufacturer takes all the responsibilities for the accuracy of product specification.
