Network emulator or RF test tool 10 of 38 Test Report N° 210209-01.TR18 A.2.2 E-Field Measurement Probe The probe is constructed using three orthogonal dipole sensors arranged on an interlocking, triangular prism core. The probe has built-in shielding against static charges and is contained within a PEEK cylindrical enclosure material at the tip.

It enables the dosimetric evaluation of left and right hand phone usage as well as body mounted usage at the flat phantom region. A cover prevents evaporation of the liquid. Reference markings on the phantom allow the complete setup of all predefined phantom positions and measurement grids by teaching three points with the robot. The phantom's characteristics are: Material Vinylester, glass fiber reinforced (VE-GF) Shell thickness 2 mm ± 0.2 mm Shell thickness 6 ± 0.2 mm at ERP Filling volume 25 Liters Dimensions Length: 1000mm / Width: 500mm 11 of 38 Test Report N° 210209-01.TR18 Rev. 03 A.2.4 Flat Phantom Phantom for compliance testing of handheld and body-mounted wireless devices in the frequency range of 30 MHz to 6 GHz. ELI is fully compatible with the IEC 62209-2 standard and all known tissue simulating liquids. ELI has been optimized regarding its performance and can be integrated into our standard phantom tables. A cover prevents evaporation of the liquid. Reference markings on the phantom allow installation of the complete setup, including all predefined phantom positions and measurement grids, by teaching three points. The phantom is compatible with all SPEAG dosimetric probes and dipoles. The phantom's characteristics are: Material Shell thickness Filling volume Dimensions Vinylester, glass fiber reinforced (VE-GF) 2 mm ± 0.2 mm 30 Liters approx. Major axis: 600mm / Minor axis: 400mm A.2.5 Device Positioner The SAR in the phantom is approximately inversely proportional to the square of the distance between the source and the liquid surface. For a source at 5 mm distance, a positioning uncertainty of 0.5 mm would produce a SAR uncertainty of 20%. Accurate device positioning is therefore crucial for accurate and repeatable measurements. The positions in which the devices must be measured are defined by the standards. The DASY device holder is designed to cope with the different positions given in the standard. It has two scales for device rotation (with respect to the body axis) and device inclination (with respect to the line between the ear reference points). The rotation center for both scales is the ear reference point (ERP). Thus the device needs no repositioning when changing the angles. The DASY device holder is constructed of low-loss POM material having the following dielectric parameters: relative permittivity =3 and loss tangent =0.02. The amount of dielectric material has been reduced in the closest vicinity of the device, since measurements have suggested that the influence of the clamp on the test results could thus be lowered. A simple but effective and easy-to-use extension for the Mounting Device; facilitates testing of larger devices according to IEC 62209-2 (e.g., laptops, cameras, etc.); lightweight and fits easily on the upper part of the Mounting Device in place of the phone positioner. The extension is fully compatible with the Twin SAM, ELI and other Flat Phantoms. 12 of 38 Test Report N° 210209-01.TR18 Data Evaluation Rev. 03 · Power Reference measurement The robot measures the E field in a specified reference position that can be either the selected section's grid reference point or a user point in this section at 4mm of the inner surface of the phantom, 2mm for frequencies above 3GHz. · Area Scan Measurement procedures for evaluating SAR from wireless handsets typically start with a coarse measurement grid to determine the approximate location of the local peak SAR values. This is known as the area-scan procedure. The SAR distribution is scanned along the inside surface of one side of the phantom head, at least for an area larger than the projection of the handset and antenna. The distance between the measured points and phantom surface should be less than 8 mm, and should remain constant (with variation less than ± 1 mm) during the entire scan in order to determine the locations of the local peak SAR with sufficient accuracy. The angle between the probe axis and the surface normal line is recommended but not required to be less than 30°. If this angle is larger than 30° and the closest point on the probe-tip housing to the phantom surface is closer than a probe diameter, the boundary effect may become larger and polarization dependent. This additional uncertainty needs to be analyzed and accounted for. To achieve this, modified test procedures and additional uncertainty analyses not described in this recommended practice may be required. The measurement and interpolation point spacing should be chosen such as to allow identification of the local peak locations to within one-half of the linear dimension of a side of the zoom-scan volume. Because a local peak having specific amplitude and steep gradients may produce a lower peak spatial-average SAR compared to peaks with slightly lower amplitude and less steep gradients, it is necessary to evaluate these other peaks as well. However, since the spatial gradients of local SAR peaks are a function of the wavelength inside the tissue-equivalent liquid and the incident magnetic field strength, it is not necessary to evaluate local peaks that are less than 2 dB or more below the global maximum peak. Two-dimensional spline algorithms (Brishoual et al. 2001; Press et al., 1996) are typically used to determine the peaks and gradients within the scanned area. If a peak is found at a distance from the scan border of less than one-half the edge dimension of the desired 1 g or 10 g cube, the measurement area should be enlarged if possible. · Zoom Scan To evaluate the peak spatial-average SAR values for 1 g or 10 g cubes, fine resolution volume scans, called zoom scans, are performed at the peak SAR locations identified during the area scan. The minimum zoom scan volume size should extend at least 1.5 times the edge dimension of a 1 g cube in all directions from the center of the scan volume, for both 1 g and 10 g peak spatial-average SAR evaluations. Along the phantom curved surfaces, the front face of the volume facing the tissue/liquid interface conforms to the curved boundary, to ensure that all SAR peaks are captured. The back face should be equally distorted to maintain the correct averaging mass. The flatness and orientation of the four side faces are unchanged from that of a cube whose orientation is within ± 30° of the line normal to the phantom at the center of the cube face next to the phantom surface. The peak local SAR locations that were determined in the area scan (interpolated values) should be used for the centers of the zoom scans. If a scan volume cannot be centered due to proximity of a phantom shape feature, the probe should be tilted to allow scan volume enlargement. If probe tilt is not feasible, the zoom-scan origin may be shifted, but not by more than half of the 1 g or 10 g cube edge dimension. After the zoom-scan measurement, extrapolations from the closest measured points to the surface, for example along lines parallel to the zoom-scan centerline, and interpolations to a finer resolution between all measured and extrapolated points are performed. Extrapolation algorithm considerations are described in 6.5.3, and 3-D spline methods (Brishoual et al., 2001; Kreyszig, 1983; Press et al., 1996) can be used for interpolation. The peak spatial-average SAR is finally determined by a numerical averaging of the local SAR values in the interpolation grid, using for example a trapezoidal algorithm for the integration (averaging). In some areas of the phantom, such as the jaw and upper head regions, the angle of the probe with respect to the line normal to the surface may be relatively large, e.g., greater than ± 30º, which could increase the boundary effect error to a larger level. In these cases, during the zoom scan a change in the orientation of the probe, the phantom, or both is recommended but not required for the duration of the zoom scan, so that the angle between the probe axis and the line normal to the surface is within 30º for all measurement points. 13 of 38 Test Report N° 210209-01.TR18 Rev. 03 · Power Drift measurement The robot re-measures the E-Field in the same reference location measured at the Power Reference. The drift measurement gives the field difference in dB from the first to the last reference reading. This allows a user to monitor the power drift of the device under test that must remain within a maximum variation of ±5%. · Post-processing The procedure for spatial peak SAR evaluation has been implemented according to the IEEE1528 and IEC 62209-1/2 standards. It can be conducted for 1g and 10g. The software allows evaluations that combine measured data and robot positions, such as: Maximum search Extrapolation Boundary correction Peak search for averaged SAR Interpolation between the measured points is performed when the resolution of the grid is not fine enough to compute the average SAR over a given mass. Extrapolation routines are used to obtain SAR values between the lowest measurement points and the inner phantom surface. The extrapolation is determined by the surface detection distance and the probe sensor offset. Several measurements at different distances are necessary for the extrapolation. 14 of 38 Test Report N° 210209-01.TR18 Rev. 03 System and Liquid Check A.4.1 System Check The system performance check verifies that the system operates within its specifications. System and operator errors can be detected and corrected. It is recommended that the system performance check be performed prior to any usage of the system in order to guarantee reproducible results. The system performance check uses normal SAR measurements in a simplified setup with a well characterized source. This setup was selected to give a high sensitivity to all parameters that might fail or vary over time. The system check does not intend to replace the calibration of the components, but indicates situations where the system uncertainty is exceeded due to drift or failure. In the simplified setup for system check, the EUT is replaced by a calibrated dipole and the power source is replaced by a controlled continuous wave generated by a signal generator. The calibrated dipole must be placed beneath the flat phantom section of the phantom at the correct distance. The equipment setup is shown below: Signal Generator Amplifier Directional coupler Power meter Calibrated dipole First, the power meter PM1 (including attenuator Att1) is connected to the cable to measure the forward power at the location of the connector (x) to the system check source. The signal generator is adjusted for the desired forward power at the connector as read by power meter PM1 after attenuation Att1 and also as coupled through Att2 to PM2. After connecting the cable to the source, the signal generator is readjusted for the same reading at power meter PM2. SAR results are normalized to a forward power of 1W to compare the values with the calibration reports results as described at IEEE/IEC62209 1528 and IEEE 1528 standards. 15 of 38 Test Report N° 210209-01.TR18 Rev. 03 A.4.2 Liquid Check The dielectric parameters check is done prior to the use of the tissue simulating liquid. The verification is made by comparing the relative permittivity and conductivity to the values recommended by the applicable standards.

Test Results Rev. 03 The herein test results were performed by: Test case measurement Conducted measurement SAR measurement Test Personnel A. Azize Gilbert R. Luciani Test Conditions B.1.1 Test SAR Test positions relative to the phantom The device under test was an Intel® Wi-Fi 6E AX211 card inside (Engineering sample) using a set of PIFA antennas. The card was operated utilizing proprietary software (DRTU version 99.3500.51.0-00830) and each channel was measured using a broadband power meter to determine the maximum average power. The SAR Test Exclusion Threshold in FCC OET KDB 447498 D01 can be applied to determine SAR test exclusion for adjacent edge configurations. All six sides of the antenna were tested for SAR compliance with the antenna placed at 15mm beneath the phantom. The adjacent edges of the antenna were positioned perpendicular to the phantom. Considering the antenna location diagrams in Annex F and the test exclusions described before, the surfaces/edges to be measured for each antenna are: Antenna Test Position Chain A · Front face · Back Face · Top edge · Bottom edge · Left edge · Right edge Chain B · Front face · Back Face · Top edge · Bottom edge · Left edge · Right edge See B.1.3.1 for a more detailed list of the applied reductions. See F.2 Test positions section for more information on the tested positions B.1.2 Test signal, Output power and Test Frequencies For 802.11 transmission modes the device was put into operation by using an own control software to program the test mode required to select the continuous transmission with 100% duty cycle. The output power of the device was set to transmit at maximum power for all tests. 20 of 38 Test Report N° 210209-01.TR18 B.1.3 Evaluation Exclusion and Test Reductions Rev. 03 B.1.3.1 SAR evaluation exclusion The SAR Test Exclusion Threshold in FCC OET KDB 447498 D01 v06 can be applied to determine SAR test exclusion for adjacent edge configurations. For 100MHz to 6GHz and test separation distances 50mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following formula: [(max. power of channel, including tune - up tolerance, mW)/(min. test separation distance, mm)] [()] (1) 3.0 1 , 7.5 10 Where: · 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 · The values 3.0 and 7.5 are referred to as numeric thresholds The test exclusions are applicable only when the minimum test separation distance is 50 mm, and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. For test separation distances > 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined using the following formulas: ( 50 (1)) + ( - 50 ) (/150), 100 1500 (2) ( 50 (1)) + ( - 50 ) 10), 1500 6 (3) LAN Antenna Band Name Output power Bottom Edge Front Face Left Edge Right Edge Top Edge Back Face Bottom Edge Left Edge Front Face Right Edge Top Edge Back Face mW dBm WLAN Chain A UNII-4 WLAN Chain B UNII-4 T: Tested position R: Reduced 21.2 131.8 <50 21.2 131.8 <50 <50 <50 <50 <50 <50 <50 <50 <50 <50 <50 T T T T T T T T T T T T See Annex F for a more detailed explanation of the separation distance related to the platform. 21 of 38 Test Report N° 210209-01.TR18 Rev. 03 B.1.3.2 General SAR test reduction According to FCC OET KDB 447498 D01, 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 W/kg or 2.0 W/kg, for 1-g or 10-g respectively, when the transmission band is 100 MHz · 0.6 W/kg or 1.5 W/kg, for 1-g or 10-g respectively, when the transmission band is between 100 MHz and 200 MHz · 0.4 W/kg or 1.0 W/kg, for 1-g or 10-g respectively, when the transmission band is 200 MHz WLAN SAR Test reduction Transmission Mode SAR test exclusion/reduction According to FCC OET KDB 248227 D01, 802.11a/g/n/ac modes have the same specified maximum output power, largest channel bandwidth, lowest order modulation and lowest data rate, the lowest order 802.11 mode is selected; i.e., 802.11a is chosen over 802.11n then 802.11ac or 802.11g is chosen over 802.11n. OFDM According to FCC OET KDB 248227 D01, an initial test configuration is determined for OFDM and DSSS transmission modes according to the channel bandwidth, modulation and data rate combination(s) with the highest maximum output power specified for production units in each standalone and aggregated frequency band. SAR is measured using the highest measured maximum output power channel. SAR test reduction for subsequent highest output test channels is determined according to reported SAR of the initial test configuration. The initial test configuration for 5 GHz OFDM transmission modes is determined by the 802.11 configuration with the highest maximum output power specified for production units, including tuneup tolerance, in each standalone and aggregated frequency band. SAR for the initial test configuration is measured using the highest maximum output power channel determined by the default power measurement procedures. According to FCC OET KDB 248227 D01, when the reported SAR of the initial test configuration is > 0.8 W/kg, SAR measurement is required for subsequent next highest measured output power channel(s) in the initial test configuration until reported SAR is 1.2 W/kg or all required channels are tested. 22 of 38 Test Report N° 210209-01.TR18 Conducted Power Measurements B.2.1 WLAN 5GHz (U-NII) B.2.1.1 5.8 (U-NII-4) Rev. 03 Band Mode 802.11a 802.11n20 U-NII-4 802.11ax20 802.11n40 802.11ax40 802.11ac80 802.11ax80 802.11ac160 802.11ax160 Initial test configuration Data Rate 6Mbps HT0 HE0 HT0 HE0 VHT0 HE0 VHT0 HE0 Ch # 169 173 177 169 173 177 169 173 177 167 175 167 175 171 171 163 163 Freq (MHz) 5845 5865 5885 5845 5865 5885 5845 5865 5885 5835 5875 5835 5875 5855 5855 5815 5815 Chain A Avg Pwr Tune-up (dBm) Pwr (dBm) NR1,3 21.00 20.90 NR1,3 20.00 20.00 20.00 19.50 20.00 20.00 20.20 20.00 20.00 21.20 21.20 21.20 21.20 20.00 20.00 15.50 16.50 Chain B Avg Pwr (dBm) Tune-up Pwr (dBm) 20.00 20.00 20.00 20.00 NR1,3 20.00 20.00 20.00 20.20 20.00 20.87 21.20 20.79 21.20 21.20 21.20 NR1,3 20.00 20.00 14.50 15.00 SAR Test?

When band gap channels between U-NII-2C and U-NII-3 band are supported channels in U-NII-2C band below 5.65 GHz are considered as one band and channels above 5.65 GHz, together with channels in 5.8 GHz U-NII-3 or §15.247 band, are considered as a separate band 3. Additional conducted power measurement is required when reported SAR is > 1.2W/kg. In case the subsequent test configuration and the channel bandwidth is smaller than the initial test configuration, all channels that overlap with the larger channel bandwidth in the initial configuration should be tested 4. The initial test configuration for 2.4 GHz and 5 GHz OFDM transmission modes is determined by the 802.11 configuration with the highest maximum output power specified for production units, including tune-up tolerance, in each standalone and aggregated frequency band. SAR for the initial test configuration is measured using the highest maximum output power channel determined by the default power measurement procedures. When multiple transmission modes (802.11a/g/n/ac/ax) have the same specified maximum output power, largest channel bandwidth, lowest order modulation and lowest data rate, lowest order 802.11 mode is selected (i.e. a, g, n, ac then ax) 5. When the reported SAR of the initial test configuration is > 0.8W/kg, SAR measurement is required for the subsequent next highest measured output power channel(s) in the initial test configuration until reported SAR is 1.2W/kg or all required channels are tested. 6. When the highest reported SAR for the initial test configuration (when applicable, include subsequent highest output channels), according to the initial test position or fixed exposure requirements, is adjusted by the ratio of the subsequent test configuration to the initial test configuration specified maximum output power and the adjusted SAR is1.2 W/Kg, SAR is not required for that subsequent test configuration. 7. SAR for subsequent highest measured maximum output power channels in the subsequent test configuration is required only when the reported SAR of the preceding higher maximum output power channel(s) in the subsequent test configuration is >1.2 W/Kg or until all required channels are tested. 23 of 38 Test Report N° 210209-01.TR18 Tissue Parameters Measurement Body TSL Freq.
