Chilingxiang, Qishantou, Santun, Houjie, Dongguan, Guangdong, China Tel: 86-769-83081888-808 Report Number: ESTE-R2309016 Date of Test: Jul. 17~Sep. 05, 2023 Date of Report: Sep. 22, 2023 FCC ID: 2AEBXET4437 EST Technology Co., Ltd Report No. ESTE-R2309016 Page 2 of 3 1. Applicable Standards FCC Part 2(Section 2.1093) FCC KDB 447498 D04 Interim General RF Exposure Guidance v01 2. Exposure Evaluation of Portable or Mobile Devices Human exposure to RF emissions from portable devices (47 CFR §2.1093), as defined by the FCC, must be evaluated with respect to the FCC-adopted limits for SAR. Evaluation of mobile devices, as defined by the FCC, may also be performed with respect to SAR limits, but in such cases it is usually simpler and more cost-effective to evaluate compliance with respect to field strength or power density limits. For certain devices that are designed to be used in both mobile and portable configurations similar to those described in 47 CFR §2.1091(d)(4), such as certain desktop phones and wireless modem modules, compliance for mobile configurations is also satisfied when the same device is evaluated for SAR compliance in portable configurations. The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 300 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. FCC ID: 2AEBXET4437 EST Technology Co., Ltd Report No. ESTE-R2309016 Page 3 of 3 3. Evaluation Results Ant gain=3dBi Ant numeric gain=1.99 Field strength = 78.03dBuV/m@3m Limited=2040*f*(0.5/20)^x, x=-log(60/(2040*f*√f))= 23.17mW EIRP={ [10 (78.03 /20) /10 6 *3] 2 / (30*1 }*1000mW =0.0191mW < 23.17mW Note: 1. We choose f=0.43392GHz to calculate MPE limit as higher frequency will have lower MPE limits. 2. SAR Test Exclusion Thresholds is 23.17mW for separation distance 5mm. Therefore, SAR test is not required. End of Test Report
