RF Exposure Info

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2501R01808E-RF-00D TR-EM-RF015 Page 344 of 347 Version 4.1 RF EXPOSURE EVALUATION MPE-Based Exemption Applicable Standard According to subpart 2.1091 systems operating under the provisions of this section shall be operated in a manner that ensures the public is not exposed to RF energy level in excess of the communication guidelines. According to KDB 447498 D04 v01 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)(3)(i)(C)] to support an exemption from further evaluation from 300 kHz through 100 GHz. R is 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: Bay Area Compliance Laboratories Corp.

The tune up conducted power and antenna gain was declared by the applicant. 2. 0dBd=2.15dBi 3. The BT, 2.4G and 5G Wi-Fi cannot transmit at same time. 4. The device contains a certified WWAN model (model: LE910C4-NFX, FCC ID: RI7LE910CXNF) Simultaneous transmitting consideration (worst case): The ratio= ERP 2.4G Wi-Fi /limit + ERP LTE B12 /limit = 119.67/768+ 222.33/358 =0.78<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
