TEL : 886-3-327-3456 Page : G1 of G3 FAX : 886-3-328-4978 FCC SAR TEST REPORT Report No. :FA550731B Appendix G. Supplemental Antenna Tuner Tests Results General Note: 1. This device implements antenna tuning techniques in the several frequency band and list as below. SAR test proposal was measured according to the normally required SAR configurations with the tuner active and worst tune state (auto tune) was used for SAR testing and this design will provide the highest power at different user scenarios and would not influence to the antenna characteristics other than impedance matching. 2. Dynamic antenna tuning mechanism is available at Ant.0 for its < 1GHz LTE and NR band. The number of supported tune codes is different for each frequency band as shown in the following table. And it’s verified that tune state results in the highest SAR configuration 3. The antenna tuner state shall be controlled remotely such that the DUT position is not moved during the series of single-point SAR measurements. 4. For each air interface, exposure condition, and antenna that supports dynamic antenna tuning (DAT), the following procedure shall be followed: a. An area scan is performed with the DUT positioned for the exposure condition with auto-tuner enabled to determine the peak SAR location b. A single-point SAR measurement (i.e., time sweep) is performed at the peak SAR location of step a (that is, with auto-tuner enabled). The auto-tuner state shall be recorded, after verifying that it is stable. If fluctuations occur, the scan procedure can be restarted, or the state with the highest SAR needs to be recorded c. Without moving the probe, or introducing any other perturbation, the auto-tuner shall be disabled, and two other adjacent tune states shall be chosen by increasing and decreasing the state identification number by 1 d. A single point SAR measurement is then performed on both chosen adjacent states and compared with the value of step b. The measured SAR for auto-tuner disabled is expected to be less than or equal to the recorded SAR of step b. If the measured SAR is higher beyond documented tolerance, then the auto-tuning feature is not working as intended and is not suitable for compliance. DAT functionality shall be removed or adjusted by the manufacturer. If the measured SAR is higher than the value of step b but within tolerance, the next adjacent state(s) shall be chosen and the measure repeated until a lower SAR value can be shown; otherwise, the DAT is considered inoperative and shall be removed or adjusted by the manufacturer. e. Repeat step b with auto-tuning enabled as a test for variability within tolerance: the previous measured value in step 2.2 shall be recovered. If the measured SAR is outside the expected tolerance, then the auto-tuning feature is considered not working as intended and not suitable for compliance. DAT functionality shall be removed or adjusted by the manufacturer f. If any single-point SAR measurement result is >1.4 W/kg, then all tune states for that particular combination of air interface, exposure condition, and antenna selection shall be evaluated with single-point SAR measurements.

This device WLAN 2.4GHz / 5.2GHz / 5.8GHz and WLAN 6GHz VLP supports Hotspot operation and Bluetooth support tethering applications. 2. The worst case reported SAR from each transmit antennas were using for SAR summation. Therefore, the following summations represent the absolute worst cases for simultaneous transmission configuration. 3. The SAR summation is calculated based on the same exposure configuration and test position from each transmit antenna worst case reported SAR results. 4. Per KDB 447498 D01v06, simultaneous transmission SAR is compliant if, i) Scalar SAR summation < 1.6W/kg. ii) SPLSR = (SAR1 + SAR2)^1.5 / (min. separation distance, mm), and the peak separation distance is determined from the square root of [(x1-x2) 2 + (y1-y2) 2 + (z1-z2) 2 ], where (x1, y1, z1) and (x2, y2, z2) are the coordinates of the extrapolated peak SAR locations in the zoom scan. iii) If SPLSR ≀ 0.04, simultaneously transmission SAR measurement is not necessary. iv) Simultaneously transmission SAR measurement, and the reported multi-band SAR < 1.6W/kg. Page : F3 of F60 FCC SAR TEST REPORT Report No. :FA550731B F.2 5G NR + LTE + WLAN + BT Sim-Tx analysis Samsung proprietary TAS feature manages transmitting power effectively in real time and ensures that overall average RF exposure from 3G/4G/5G NR WWAN including NTN, 5GNR EN-DC, and LTE/FR1 intra-band/inter-band uplink CA are in compliance with RF Exposure requirements, while the RF exposure from 2G and WLAN/BT radios is managed using the legacy approach, i.e., through a fixed power back-off if needed. The test device features a TAS function to keep average RF exposure below the given limit for all cases while allowing temporarily high power transmission for better performance For the 5GNR EN-DC, the power ratio factors are g1 and g2 for LTE and NR respectively. The purpose of these power ratio factors is to split the available SAR budget among different RATs, so g1 + g2 ≀ 1. The value of g1 is computed based on the need of the anchor (LTE) and can be changed if the anchor changes its power request. Based on the SAR Budget portion allocated to the anchor, the value of g2 will be computed. At steady state (where all RATs are being on for a while), the allocated power ratio factors will guarantee that the total exposure ratio never exceeds the highest exposure of either one. g1* LTEexposure + g2* NRexposure ≀ 1.0, then, g1* LTEexposure + g2* NRexposure ≀ max ( LTEexposure , NRexposure ) In simultaneous transmission for this device, 5G NR and LTE transmission are managed and controlled by Samsung S.LSI TAS, while the RF exposure from WLAN, BT radios are managed usi…

Power verification introduction ⚫ This device supports the manufacturer’s proprietary power reduction mechanisms for cellular and Wi- Fi transmitters. Further details of the specific mechanisms for the power reduction mechanism can be found in the Operational Description ⚫ Demonstration of proper functioning of the detection and triggering mechanisms to support the corresponding RF exposure conditions, the verification plan consists of measuring the power levels of the cellular and Wi-Fi transmitters at each wireless technology under different operating conditions related to the power reduction mechanisms. ⚫ This device incorporates the WWAN TAS algorithm feature and through under varying Tx power transmission scenarios in real-time to maintain the time-averaged Tx power compliant with FCC RF exposure requirement. In this power validation purpose is to demonstrate of proper functioning of the detection and triggering mechanisms to support the corresponding RF exposure conditions. In order to avoid real-time TX power varying may affect monitor output power related to the power reduction mechanisms, therefore WWAN real-time TX power varying was disabled and keep in static output power for power reduction mechanism validation. ⚫ For testing purposes, the device was measured against each Index supported for the cellular and Wi- Fi technologies. The target power level and measured power levels are detailed in the following table and clearly shows that each power reduction mechanism operates as expected. 2. Power verification procedure ⚫ The verification is through a base station simulator is used to establish a conducted RF connection and record output power under different operating conditions related to the power reduction mechanisms. ⚫ Verification of power reduction levels for Wi-Fi is performed with cellular transmitters on and off, for cellular is performed with Wi-Fi transmitters on and off. ⚫ Verification of RCV mechanism is via establish voice call and audio routed through the earpiece to record output power under head power states. ⚫ Verification of Hotspot power reduction is via establish data connection and enable hotspot feature to record output power under hotspot power state. ⚫ Verification of Body Detector mechanism is via establish data connection to record output power under body worn power state. ➒ On a stationary object (placed on a table) ➒ In-hand or on knee ➒ Body detect and monitor period validation TEL : 886-3-327-3456 Page : E2 of E5 FAX : 886-3-328-4978 FCC SAR TEST REPORT Report No. : FA550731B 3.
