Standalone MPE Result As declared by the Applicant, the EUT is a wireless device used in a fix application, at least 20 cm from any body part of the user or nearby persons; from the maximum EUT RF output power, the minimum separation distance, r =20cm, as well as the gain of the used antenna is refer to section 4, the RF power density can be obtained. Modulation Type Output power Antenna Gain (dBi) Antenna Gain (linear) MPE (mW/cm 2 ) MPE Limits (mW/cm 2 ) dBm mW WIFI 15 31.623 2.47 1.766 0.01111 1.0000 Remark: 1. Output power (Peak) including turn-up tolerance; 2. MPE evaluate distance is 20cm from user manual provide by manufacturer. 7. Conclusion The measurement results comply with the FCC Limit per 47 CFR 2.1091 for the uncontrolled RF Exposure of mobile device. ----------------THE END OF REPORT---------------
