RF Exposure evaluation FCC ID: 2BBU4-KR-S1090-6560 Exposure category: General population/uncontrolled environment EUT Type: Production Unit Device Type: Mobile Device 1. Reference According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. KDB447498 D01: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies 2. Limit Limits for Maximum Permissible Exposure (MPE)/Controlled Exposure Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density (mW/cm²) Averaging Time (minute) Limits for Occupational/Controlled Exposure 0.3 – 3.0 3.0 – 30 30 – 300 300 – 1500 1500 – 100,000 614 1842/f 61.4 / / 1.63 4.89/f 0.163 / / (100) * (900/f 2 )* 1.0 f/300 5 6 6 6 6 6 Limits for Maximum Permissible Exposure (MPE)/Uncontrolled Exposure Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density (mW/cm²) Averaging Time (minute) Limits for Occupational/Controlled Exposure 0.3 – 3.0 3.0 – 30 30 – 300 300 – 1500 1500 – 100,000 614 824/f 27.5 / / 1.63 2.19/f 0.073 / / (100) * (180/f 2 )* 0.2 f/1500 1.0 30 30 30 30 30 F=frequency in MHz *=Plane-wave equivalent power density 3. 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 KR-S1090-6560-BT 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 0.82dBi for 2400-2500MHz; 5. Manufacturing Tolerance BLE GFSK(Peak) Channel Channel 00 Channel 19 Channel 39 Target (dBm) 3.0 4.0 4.0 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 0.82dBi, 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 5.0 3.1623 0.82 1.2078 0.0009 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---------------
