FCC SAR TEST REPORT Report No. : FA931948 4. RF Exposure Limits 4.1 Uncontrolled Environment Uncontrolled Environments are defined as locations where there is the exposure of individuals who have no knowledge or control of their exposure. The general population/uncontrolled exposure limits are applicable to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general public would come under this category when exposure is not employment-related; for example, in the case of a wireless transmitter that exposes persons in its vicinity. 4.2 Controlled Environment Controlled Environments are defined as locations where there is exposure that may be incurred by persons who are aware of the potential for exposure, (i.e. as a result of employment or occupation). In general, occupational/controlled exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who have been made fully aware of the potential for exposure and can exercise control over their exposure. The exposure category is also applicable when the exposure is of a transient nature due to incidental passage through a location where the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. Limits for Occupational/Controlled Exposure (W/kg) Limits for General Population/Uncontrolled Exposure (W/kg) 1. Whole-Body SAR is averaged over the entire body, partial-body SAR is averaged over any 1gram of tissue defined as a tissue volume in the shape of a cube. SAR for hands, wrists, feet and ankles is averaged over any 10 grams of tissue defined as a tissue volume in the shape of a cube.

FCC SAR TEST REPORT Report No. : FA931948 5. Specific Absorption Rate (SAR) 5.1 Introduction SAR is related to the rate at which energy is absorbed per unit mass in an object exposed to a radio field. The SAR distribution in a biological body is complicated and is usually carried out by experimental techniques or numerical modeling. The standard recommends limits for two tiers of groups, occupational/controlled and general population/uncontrolled, based on a person’s awareness and ability to exercise control over his or her exposure. In general, occupational/controlled exposure limits are higher than the limits for general population/uncontrolled. 5.2 SAR Definition The SAR definition is the time derivative (rate) of the incremental energy (dW) absorbed by (dissipated in) an incremental mass (dm) contained in a volume element (dv) of a given density (ρ). The equation description is as below: 𝐝 𝐝𝐖 𝐝 𝐝𝐖 𝐒𝐀𝐑 = ( )= ( ) 𝐝𝐭 𝐝𝐦 𝐝𝐭 𝛒𝐝𝐯 SAR is expressed in units of Watts per kilogram (W/kg) 𝛔|𝐄|𝟐 𝐒𝐀𝐑 = 𝛒 Where: σ is the conductivity of the tissue, ρ is the mass density of the tissue and E is the RMS electrical field strength.

FCC SAR TEST REPORT Report No. : FA931948 7. Measurement Procedures The measurement procedures are as follows: <Conducted power measurement> (a) For WWAN power measurement, use base station simulator to configure EUT WWAN transmission in conducted connection with RF cable, at maximum power in each supported wireless interface and frequency band. (b) Read the WWAN RF power level from the base station simulator. (c) For WLAN/BT power measurement, use engineering software to configure EUT WLAN/BT continuously transmission, at maximum RF power in each supported wireless interface and frequency band (d) Connect EUT RF port through RF cable to the power meter, and measure WLAN/BT output power <SAR measurement> (a) Use base station simulator to configure EUT WWAN transmission in radiated connection, and engineering software to configure EUT WLAN/BT continuously transmission, at maximum RF power, in the highest power channel. (b) Place the EUT in the positions as Appendix D demonstrates. (c) Set scan area, grid size and other setting on the DASY software. (d) Measure SAR results for the highest power channel on each testing position. (e) Find out the largest SAR result on these testing positions of each band (f) Measure SAR results for other channels in worst SAR testing position if the reported SAR of highest power channel is larger than 0.8 W/kg According to the test standard, the recommended procedure for assessing the peak spatial-average SAR value consists of the following steps: (a) Power reference measurement (b) Area scan (c) Zoom scan (d) Power drift measurement 7.1 Spatial Peak SAR Evaluation The procedure for spatial peak SAR evaluation has been implemented according to the test standard. It can be conducted for 1g and 10g, as well as for user-specific masses. The DASY software includes all numerical procedures necessary to evaluate the spatial peak SAR value. The base for the evaluation is a "cube" measurement. The measured volume must include the 1g and 10g cubes with the highest averaged SAR values. For that purpose, the center of the measured volume is aligned to the interpolated peak SAR value of a previously performed area scan. The entire evaluation of the spatial peak values is performed within the post-processing engine (SEMCAD). The system always gives the maximum values for the 1g and 10g cubes. The algorithm to find the cube with highest averaged SAR is divided into the following stages: (a) Extraction of the measured data (grid and values) from the Zoom Scan (b) Calculation of the SAR value at every measurement point based on all stored data (A/D values and measurement parameters) (c) Generation of a high-resolution mesh within the measured volume (d) Interpolation of all measured values form the measurement grid to the high-resolution grid (e) Extrapolation of the entire 3-D field distribution to the phantom surface over the distance from sensor to surface (f) Calculation of the averaged SAR within masses of 1g and 10g TEL : 886-3-327-3456 Page 12 of 32 FAX : 886-3-328-4978 Issued Date : May 28, 2019 Form version: 181113

FCC SAR TEST REPORT Report No. : FA931948 7.2 Power Reference Measurement The Power Reference Measurement and Power Drift Measurements are for monitoring the power drift of the device under test in the batch process. The minimum distance of probe sensors to surface determines the closest measurement point to phantom surface. This distance cannot be smaller than the distance of sensor calibration points to probe tip as defined in the probe properties. 7.3 Area Scan The area scan is used as a fast scan in two dimensions to find the area of high field values, before doing a fine measurement around the hot spot. The sophisticated interpolation routines implemented in DASY software can find the maximum found in the scanned area, within a range of the global maximum. The range (in dB0 is specified in the standards for compliance testing. For example, a 2 dB range is required in IEEE standard 1528 and IEC 62209 standards, whereby 3 dB is a requirement when compliance is assessed in accordance with the ARIB standard (Japan), if only one zoom scan follows the area scan, then only the absolute maximum will be taken as reference. For cases where multiple maximums are detected, the number of zoom scans has to be increased accordingly.

FCC SAR TEST REPORT Report No. : FA931948 7.4 Zoom Scan Zoom scans are used assess the peak spatial SAR values within a cubic averaging volume containing 1 gram and 10 gram of simulated tissue. The zoom scan measures points (refer to table below) within a cube shoes base faces are centered on the maxima found in a preceding area scan job within the same procedure. When the measurement is done, the zoom scan evaluates the averaged SAR for 1 gram and 10 gram and displays these values next to the job’s label. Zoom scan parameters extracted from FCC KDB 865664 D01v01r04 SAR measurement 100 MHz to 6 GHz. 7.5 Volume Scan Procedures The volume scan is used for assess overlapping SAR distributions for antennas transmitting in different frequency bands. It is equivalent to an oversized zoom scan used in standalone measurements. The measurement volume will be used to enclose all the simultaneous transmitting antennas. For antennas transmitting simultaneously in different frequency bands, the volume scan is measured separately in each frequency band. In order to sum correctly to compute the 1g aggregate SAR, the EUT remain in the same test position for all measurements and all volume scan use the same spatial resolution and grid spacing. When all volume scan were completed, the software, SEMCAD postprocessor can combine and subsequently superpose these measurement data to calculating the multiband SAR. 7.6 Power Drift Monitoring All SAR testing is under the EUT install full charged battery and transmit maximum output power. In DASY measurement software, the power reference measurement and power drift measurement procedures are used for monitoring the power drift of EUT during SAR test. Both these procedures measure the field at a specified reference position before and after the SAR testing. The software will calculate the field difference in dB. If the power drifts more than 5%, the SAR will be retested. TEL : 886-3-327-3456 Page 14 of 32 FAX : 886-3-328-4978 Issued Date : May 28, 2019 Form version: 181113

FCC SAR TEST REPORT Report No. : FA931948 10. Conducted RF Output Power (Unit: dBm) <WLAN Conducted Power> General Note: 1. The reported TX power in EMC report is per actual shipping power setting and measured in this unit, the power set for SAR test is included the tune-up tolerance which is considered as worst case. 2. Per KDB 248227 D01v02r02, SAR test reduction is determined according to 802.11 transmission mode configurations and certain exposure conditions with multiple test positions. In the 2.4 GHz band, separate SAR procedures are applied to DSSS and OFDM configurations to simplify DSSS test requirements. For OFDM, in both 2.4 and 5 GHz bands, an initial test configuration must be determined for each standalone and aggregated frequency band, according to the transmission mode configuration with the highest maximum output power specified for production units to perform SAR measurements. If the same highest maximum output power applies to different combinations of channel bandwidths, modulations and data rates, additional procedures are applied to determine which test configurations require SAR measurement. When applicable, an initial test position may be applied to reduce the number of SAR measurements required for next to the ear, UMPC mini-tablet or hotspot mode configurations with multiple test positions. 3. For 2.4 GHz 802.11b DSSS, either the initial test position procedure for multiple exposure test positions or the DSSS procedure for fixed exposure position is applied; these are mutually exclusive. For 2.4 GHz and 5 GHz OFDM configurations, the initial test configuration is applied to measure SAR using either the initial test position procedure for multiple exposure test position configurations or the initial test configuration procedures for fixed exposure test conditions. Based on the reported SAR of the measured configurations and maximum output power of the transmission mode configurations that are not included in the initial test configuration, the subsequent test configuration and initial test position procedures are applied to determine if SAR measurements are required for the remaining OFDM transmission configurations. In general, the number of test channels that require SAR measurement is minimized based on maximum output power measured for the test sample(s). 4. For OFDM transmission configurations in the 2.4 GHz and 5 GHz bands, When the same maximum power is specified for multiple transmission modes in a frequency band, the largest channel bandwidth, lowest order modulation, lowest data rate and lowest order 802.11a/g/n/ac mode is used for SAR measurement, on the highest measured output power channel for each frequency band. 5. DSSS and OFDM configurations are considered separately according to the required SAR procedures. SAR is measured in the initial test position using the 802.11 transmission mode configuration required by the DSSS procedure or initial test configuration and subsequent test configuration(s) according to the OFDM procedures.18 The initial test position procedure is described in the following: a. When the reported SAR of the initial test position is ≤ 0.4 W/kg, further SAR measurement is not required for the other test positions in that exposure configuration and 802.11 transmission mode combinations within the frequency band or aggregated band. b. When the reported SAR of the test position is > 0.4 W/kg, SAR is repeated for the 802.11 transmission mode configuration tested in the initial test position to measure the subsequent next closet/smallest test separation distance and maximum coupling test position on the highest maximum output power channel, until the report SAR is ≤ 0.8 W/kg or all required test position are tested. c. For all positions/configurations, when the reported SAR is > 0.8 W/kg, SAR is measured for these test positions/configurations on the subsequent next highest measured output power channel(s) until the reported SAR is ≤ 1.2 W/kg or all required channels are tested.

The below table, when the distance is < 50 mm exclusion threshold is "Ratio", when the distance is > 50 mm exclusion threshold is "mW" 2. Maximum power is the source—based time—average power and represents the maximum RF output power among production units 3. Per KDB 447498 DO1v06, for larger devices, the test separation distance of adjacent edge configuration is determined by the closest separation between the antenna and the user. 4. Per KDB 447498 DO1v06, standalone SAR test exclusion threshold is applied; If the test separation distance is < 5mm, 5mm is used to determine SAR exclusion threshold. 5. Per KDB 447498 DO1v06, the 1—g and 10—g SAR test exclusion thresholds for 100 MHz to 6 GHz at fest separation distances < 50 mm are determined by: [(max. power of channel, including tune—up tolerance, mW)/(min. test separation distance, mm)] «[N[(GHz)] < 3.0 for 1—g SAR and < 7.5 for 10—g extremity SAR * f(GHz) is the RF channel transmit frequency in GHz * Power and distance are rounded to the nearest mW and mm before calculation * The result is rounded to one decimal place for comparison 6. Per KDB 447498 DO1v06, at 100 MHz to 6 GHz and for fest separation distances > 50 mm, the SAR test exclusion threshold is determined according to the following a) [Threshold at 50 mm in step 1) + (test separation distance — 50 mm)—( f(MHz)/150)] mW, at 100 MHz to 1500 MHz b) [Threshold at 50 mm in step 1) + (test separation distance — 50 mm}—10] mW at > 1500 MHz and < 6 GHz 2462MHz 5825MHz 20.5 17 112.0 50.0 5.00 5.00 35.2 24.1 Yes Yes 5.00 5.00 35.2 24.1 Yes Yes 60.18 60.18 197.0 164.0 185.90 185.90 1455.0 1421.0 189.65 189.65 1492.0 1459.0 201.65 201.65 1612.0 1579.0 TEL : 886—3—327—3456 Page 27 of 32 FAX : 886—3—328—4978 Issued Date : May 28, 2019 Form version: 181113

seorrow cas._FCC SAR TEST REPORT Report No. : FA931948 12. SAR Test Results General Note: 1. Per KDB 447498 DO1v06, the reported SAR is the measured SAR value adjusted for maximum tune—up tolerance. a. Tune—up scaling Factor = tune—up limit power (mW) / EUT RF power (mW), where tune—up limit is the maximum rated power among all production units. b. For SAR testing of WLAN signal with non—100% duty cycle, the measured SAR is scaled—up by the duty cycle scaling factor which is equal to "1/(duty cycle)" c.. For WLAN/Bluetooth: Reported SAR(W/kg)= Measured SAR(W/kg)* Duty Cycle scaling factor * Tune—up scaling factor 2. Per KDB 447498 DO1v06, for each exposure position, testing of other required channels within the operating mode of a frequency band is not required when the reported 1—g or 10—g SAR for the mid—band or highest output power channel is: > <0.8 Wikg or 2.0 Wikg, for 1—g or 10—g respectively, when the transmission band is S 100 MHz <0.6 Wikg or 1.5 Wikg, for 1—g or 10—g respectively, when the transmission band is between 100 MHz and 200 MHz > <0.4 Wikg or 1.0 Wikg, for 1—g or 10—g respectively, when the transmission band is > 200 MHz 3. Per KDB 865664 DO1v01r04, for each frequency band, repeated SAR measurement is required only when the measured SAR is 20.8W/kq. WLAN Note: 1. Per KDB 248227 DQ1v02r02, for 2.4GHz 802.11g/n SAR testing is not required when the highest reported SAR for DSSS is adjusted by the ratio of OFDM to DSSS specified maximum output power and the adjusted SAR is < 1.2 Wikq 2. Per KDB 248227 DO1v02r02, U—NIl—1 SAR testing is not required when the U—NII—2A band highest reported SAR for a test configuration is S 1.2 Wikg, SAR is not required for U—NII—1 band. 3. When the reported SAR of the test position is > 0.4 W/kg, SAR is repeated for the 802.11 transmission mode configuration tested in the initial test position to measure the subsequent next closet/‘smallest test separation distance and maximum coupling test position on the highest maximum output power channel, until the report SAR is < 0.8 W/kg or all required test position are tested. 4. For all positions / configurations, when the reported SAR is > 0.8 W/kg, SAR is measured for these test positions / configurations on the subsequent next highest measured output power channel(s) until the reported SAR is S 1.2 W/kg or all required channels are tested. 5.

Per KDB 865664 D01v01r04, for each frequency band, repeated SAR measurement is required only when the measured SAR is ≥0.8W/kg. 2. Per KDB 865664 D01v01r04, if the ratio among the repeated measurement is ≤ 1.2 and the measured SAR <1.45W/kg, only one repeated measurement is required. 3. The ratio is the difference in percentage between original and repeated measured SAR. 4. All measurement SAR result is scaled-up to account for tune-up tolerance and is compliant.

seorron cas. _FCC SAR TEST REPORT Report No. : FA931948 13. Simultaneous Transmission Analysis Simultaneous Transmission Configurations 2.4GHz WLAN + Bluetooth 2.4GHz WLAN + 5GHz WLAN 5GHz WLAN + Bluetooth General Note: 1. WLAN/BT coexistence mode : (i) WLAN 5GHz 802.1 1a/an (or 11ac) transmit concurrent with Bluetooth. (ii) WLAN 2.4GHz timely shared coexistence with Bluetooth. 2. EUT will choose either WLAN 2.4GHz or WLAN 5GHz according to the network signal condition; therefore, 2.4GHz WLAN and 5GHz WLAN will not operate simultaneously at any moment. The Scaled SAR summation is calculated based on the same configuration and test position. & 4. Per KDB 447498 DO1v08, simultaneous transmission SAR is compliant if, i) Scalar SAR summation < 1.6W/kg. ii) SPLSR = (SAR1 + SARZ)M1.5 / (min. separation distance, mm), and the peak separation distance is determined from the square root of [(x1—x2)2 + (y1—y2)2 + (21—22)2], where (x1, y1, z1) and (x2, y2, 22) 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. 13.1 Body Exposure Conditions 1 i e orobscuc ki‘ Ccaa Summed 1g SAR 1g SAR 1g SAR (Wikg) (Citoh (Wikg) Bottom Face at Omm 0.320 0.006 0.326 Edge 1 at Omm 1.148 0.023 1171 Test Engineer : Mood Huang and Jay Jian TEL : 886—3—327—3456 Page 31 of 32 FAX : 886—3—328—4978 Issued Date : May 28, 2019 Form version: 181113

FCC SAR TEST REPORT Report No. : FA931948 14. Uncertainty Assessment Per KDB 865664 D01 SAR measurement 100MHz to 6GHz, when the highest measured 1-g SAR within a frequency band is < 1.5 W/kg and the measured 10-g SAR within a frequency band is < 3.75 W/kg. The expanded SAR measurement uncertainty must be ≤ 30%, for a confidence interval of k = 2. If these conditions are met, extensive SAR measurement uncertainty analysis described in IEEE Std 1528-2013 is not required in SAR reports submitted for equipment approval. For this device, the highest measured 1-g SAR is less 1.5W/kg. Therefore, the measurement uncertainty table is not required in this report. 15.
