General Description of EUT EUT Name : 10 Inch Wi-Fi Digital Picture Frame Models No. : PDWX-1050B, PDWX-1050C, PDWX-1050G Model Different : All these models are identical in the same PCB, layout and electrical circuit, The only difference is model name. Product Description : Operation Frequency: 802.11b/g/n(HT20): 2412MHz~2462MHz 802.11n(HT40): 2422MHz~2452MHz Number of Channel: 802.11b/g/n(HT20):11 channels 802.11n(HT40): 7 channels RF Output Power: 802.11b:17.069dBm(MAX) Antenna Gain: 1.55dBi PIFA Antenna Power Rating : Adapter(THX-050200KV) Input: 100-240V~, 50/60Hz, 0.65A MAX Output: DC 5V2.0A Adapter(SR-C6050200U2) Input: 100-240V~, 50/60Hz, 0.35A MAX Output: DC 5V2.0A Software Version : N/A Hardware Version : BND-RK3126-D916 A1.0 Connecting I/O Port(S) : : Please refer to the User's Manual Remark : the evaluation report used the EUT(20210608-07-02#). Report No.: TB-MPE181226 Page: 2 of 3 TB-RF-075-1.0 MPE Calculations for WIFI 1. Antenna Gain: PIFA Antenna:1.55dBi. 2. EUT Operation Condition: Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 3. Exposure Evaluation: Equation from page 18 of OET Bulletin 65, Edition 97-01 S=(PG)/4πR 2 Where S: power density P: power input to the 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. Test Result: 2.4G WiFi Mode Conducted Power(max) (dBm) Turn-up Power (dB) Max tune up power (dBm) [P] ANT Gain (dBi) [G] Distance (cm) [R] Power Density (mW/ cm 2 ) [S] Limit of Power Density (mW/ cm 2 ) (S) 802.11B 17.069 17±1 18 1.55 20 0.01794 1 802.11G 15.587 15±1 16 1.55 20 0.01132 1 802.11N(HT20) 15.482 15±1 16 1.55 20 0.01132 1 802.11N(HT40) 13.548 14±1 15 1.55 20 0.00899 1 5. Conclusion: As specified in Table 1B of 47 CFR 1.1310- Limits for Maximum Permissible Exposure (MPE), Limits for General Population/ Uncontrolled Exposure Frequency Range (MHz) Power density (mW/ cm 2 ) 300-1,500 F/1500 1,500-100,000 1.0 Report No.: TB-MPE181226 Page: 3 of 3 TB-RF-075-1.0 For 2.4WIFI:2412~2462 MHz MPE limit S: 1mW/ cm 2 The MPE is calculated as 0.01794mW / cm 2 < limit 1mW / cm 2 . So, RF exposure limit warning or SAR test are not required. The EUT will only be used with a separation of 20cm or greater between the antenna and nearby persons and can therefore be considered a mobile transmitter per 47 CFR2.1091 (b). The RF Exposure Information page from the manual is included here for reference. Note For a more detailed features description, please refer to the RF Test Report. 6. Conclusion: The measurement results comply with the FCC Limit per 47 CFR 2.1091 for the uncontrolled RF Exposure of mobile device. -----END OF REPORT-----
