MPE Calculation Method Predication of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna 4. Antenna Information LK-B15 can only use antennas certificated as follows provided by manufacturer; Antenna No. Model No. of antenna: Type of antenna: Gain of the antenna (Max.) Frequency range: BLE / PCB antenna 0.00dBi for 2400-2500MHz; 5. Manufacturing Tolerance BLE GFSK(Peak) Channel Channel 00 Channel 19 Channel 39 Target (dBm) 1.0 1.0 1.0 Tolerance ±(dB) 1.0 1.0 1.0 6. 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 0.0dBi, 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 BLE 2.0 1.5849 0.0 1.000 0.0003 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---------------
