According to KDB 447498 D04 Interim General RF Exposure Guidance MPE-Based Exemption: General frequency and separation-distance dependent MPE-based effective radiated power(ERP) thresholds are in Table B.1 [Table 1 of § 1.1307(b)(1)(i)(C)] to support an exemptionfrom further evaluation from 300 kHz through 100 GHz. Ris the minimum separation distance in meters f = frequency in MHz For multiple RF sources: Multiple RF sources are exempt if: in the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation: Shenzhen Accurate Technology Co., Ltd.

The antenna gain and tune up conducted power was declared by the applicant. 2. The Wi-Fi and DECT can transmit at same time, the 2.4G Wi-Fi & 5G Wi-Fi cannot transmit Simultaneously Simultaneous transmitting consideration (worst case): The ratio=ERP DECT /limit+ERP Wi-Fi /limit=0.064/0.768+0.061/0.768=0.163＜1.0, so simultaneous exposure is compliant. To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons. Result: Compliant.
