FCC SAR Test Report Report No. : FA2N0801-03 4. Specific Absorption Rate (SAR) 4.1 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. 4.2 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) SAR measurement can be either related to the temperature elevation in tissue by 𝛅𝐓 𝐒𝐀𝐑 = 𝐂 ( ) 𝛅𝐭 Where: C is the specific heat capacity, δT is the temperature rise and δt is the exposure duration, or related to the electrical field in the tissue by 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. However for evaluating SAR of low power transmitter, electrical field measurement is typically applied. SPORTON INTERNATIONAL INC.

FCC SAR Test Report Report No. : FA2N0801-03 5.4 Robot The SPEAG DASY system uses the high precision robots (DASY4: RX90BL; DASY5: TX90XL) type from Stäubli SA (France). For the 6-axis controller system, the robot controller version (DASY4: CS7MB; DASY5: CS8c) from Stäubli is used. The Stäubli robot series have many features that are important for our application:  High precision (repeatability ±0.035 mm)  High reliability (industrial design)  Jerk-free straight movements  Low ELF interference (the closed metallic construction shields against motor control fields) Fig 5.4 Photo of DASY4 Fig 5.5 Photo of DASY5 5.5 Measurement Server The measurement server is based on a PC/104 CPU board with CPU (DASY4: 166 MHz, Intel Pentium; DASY5: 400 MHz, Intel Celeron), chipdisk (DASY4: 32 MB; DASY5: 128 MB), RAM (DASY4: 64 MB, DASY5: 128 MB). The necessary circuits for communication with the DAE electronic box, as well as the 16 bit AD converter system for optical detection and digital I/O interface are contained on the DASY I/O board, which is directly connected to the PC/104 bus of the CPU board. The measurement server performs all the real-time data evaluation for field measurements and surface detection, controls robot movements and handles safety operations.

FCC SAR Test Report Report No. : FA2N0801-03 5.6 Phantom <SAM Twin Phantom> Shell Thickness 2 ± 0.2 mm; Center ear point: 6 ± 0.2 mm Filling Volume Approx. 25 liters Dimensions Length: 1000 mm; Width: 500 mm; Height: adjustable feet Measurement Areas Left Hand, Right Hand, Flat Phantom Fig 5.8 Photo of SAM Phantom The bottom plate contains three pair of bolts for locking the device holder. The device holder positions are adjusted to the standard measurement positions in the three sections. A white cover is provided to tap the phantom during off-periods to prevent water evaporation and changes in the liquid parameters. On the phantom top, three reference markers are provided to identify the phantom position with respect to the robot. <ELI4 Phantom> Shell Thickness 2 ± 0.2 mm (sagging: <1%) Filling Volume Approx. 30 liters Dimensions Major ellipse axis: 600 mm Minor axis: 400 mm Fig 5.9 Photo of ELI4 Phantom The ELI4 phantom is intended for compliance testing of handheld and body-mounted wireless devices in the frequency range of 30 MHz to 6 GHz. ELI4 is fully compatible with standard and all known tissue simulating liquids. SPORTON INTERNATIONAL INC. Page Number : 11 of 33 TEL : 886-3-327-3456 Report Issued Date : Aug. 19, 2013 FAX : 886-3-328-4978 Report Version : Rev. 01 FCC ID : Q87-WUSB6300

FCC SAR Test Report Report No. : FA2N0801-03 5.7 Device Holder <Device Holder for SAM Twin Phantom> 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 different positions given in the standard. It has two scales for the device rotation (with respect to the body axis) and the 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 ε = 3 and loss tangent δ = 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. Fig 5.10 Device Holder <Laptop Extension Kit> The extension is lightweight and made of POM, acrylic glass and foam. It fits easily on the upper part of the mounting device in place of the phone positioned. The extension is fully compatible with the SAM Twin and ELI phantoms.

seorroncas. FCC SAR Test Report Report No. : FA2N0801—03 5.8 Data Storage and Evaluation 5.7.1 Data Storage The DASY software stores the assessed data from the data acquisition electronics as raw data (in microvolt readings from the probe sensors), together with all the necessary software parameters for the data evaluation (probe calibration data, liquid parameters and device frequency and modulation data) in measurementfiles. The post—processing software evaluates the desired unit and format for output each time the data is visualized or exported. This allows verification of the complete software setup even after the measurement and allows correction of erroneous parameter settings. For example, if a measurement has been performed with an incorrect crest factor parameter in the device setup, the parameter can be corrected afterwards and the data can be reevaluated. The measured data can be visualized or exported in different units or formats, depending on the selected probe type (e.g., [V/im], [A/m], [mW/g]). Some of these units are not available in certain situations or give meaningless results, e.g., a SAR—output in a non—lose media, will always be zero. Raw data can also be exported to perform the evaluation with other software packages. 5.7.2 Data Evaluation The DASY post—processing software (SEMCAD) automatically executes the following procedures to calculate the field units from the microvolt readings at the probe connector. The parameters used in the evaluation are stored in the configuration modules of the software : Probe parameters : — Sensitivity Norm; &o, an, & — Conversion factor ConvF, — Diode compression point dep: Device parameters : — Frequency f — Crest factor cf Media parameters : — Conductivity 0 — Density P These parameters must be set correctly in the software. They can be found in the component documents or they can be imported into the software from the configuration files issued for the DASY components. in the direct measuring mode of the multi—meter option, the parameters of the actual system setup are used. In the scan visualization and export modes, the parameters stored in the corresponding documentfiles are used. The first step of the evaluation is a linearization of the fitered input signal to account for the compression characteristics of the detector diode. The compensation depends on the input signal, the diode type and the DC—transmission factor from the diode to the evaluation electronics. If the exciting field is pulsed, the crest factor of the signal must be known to correctly compensate for peak power. SPORTON INTERNATIONAL INC.

The calibration certificate of DASY can be referred to appendix C of this report. 2. Referring to KDB 865664 D01v01r01, the dipole calibration interval can be extended to 3 years with justification. The dipoles are also not physically damaged, or repaired during the interval. 3. The Insertion Loss calibration of Dual Directional Coupler and Attenuator were characterized via the network analyzer and compensated during system check. 4. In system check we need to monitor the level on the power meter, and adjust the power amplifier level to have precise power level to the dipole; the measured SAR will be normalized to 1W input power according to the ratio of 1W to the input power to the dipole. For system check, the calibration of the power amplifier is deemed not critically required for correct measurement; the power meter is critical and we do have calibration for it 5. Attenuator 1 insertion loss is calibrated by the network Analyzer, which the calibration is valid, before system check. SPORTON INTERNATIONAL INC.

FCC SAR Test Report Report No. : FA2N0801-03 7. System Verification Procedures Each DASY system is equipped with one or more system validation kits. These units, together with the predefined measurement procedures within the DASY software, enable the user to conduct the system performance check and system validation. System validation kit includes a dipole, tripod holder to fix it underneath the flat phantom and a corresponding distance holder. 7.1 Purpose of System Performance 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. 7.2 System Setup In the simplified setup for system evaluation, the EUT is replaced by a calibrated dipole and the power source is replaced by a continuous wave that comes from a signal generator. The calibrated dipole must be placed beneath the flat phantom section of the SAM twin phantom with the correct distance holder. The distance holder should touch the phantom surface with a light pressure at the reference marking and be oriented parallel to the long side of the phantom.

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 E 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 SPORTON INTERNATIONAL INC.

FCC SAR Test Report Report No. : FA2N0801-03 9.1 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 9.2 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. SPORTON INTERNATIONAL INC.

FCC SAR Test Report Report No. : FA2N0801-03 9.3 Area & Zoom Scan Procedures First Area Scan is used to locate the approximate location(s) of the local peak SAR value(s). The measurement grid within an Area Scan is defined by the grid extent, grid step size and grid offset. Next, in order to determine the EM field distribution in a three-dimensional spatial extension, Zoom Scan is required. The Zoom Scan is performed around the highest E-field value to determine the averaged SAR-distribution over 10 g. Area scan and zoom scan resolution setting follows KDB 865664 D01v01 quoted below. For any secondary peaks found in the area scan which are within 2 dB of the maximum peak and are not within this zoom scan, the zoom scan should be repeated SPORTON INTERNATIONAL INC.

FCC SAR Test Report Report No. : FA2N0801-03 9.4 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. 9.5 SAR Averaged Methods In DASY, the interpolation and extrapolation are both based on the modified Quadratic Shepard’s method. The interpolation scheme combines a least-square fitted function method and a weighted average method which are the two basic types of computational interpolation and approximation. Extrapolation routines are used to obtain SAR values between the lowest measurement points and the inner phantom surface. The extrapolation distance is determined by the surface detection distance and the probe sensor offset. The uncertainty increases with the extrapolation distance. To keep the uncertainty within 1% for the 1 g and 10 g cubes, the extrapolation distance should not be larger than 5 mm. 9.6 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. SPORTON INTERNATIONAL INC.

Per KDB 865664 D01v01, for each frequency band, repeated SAR measurement is required only when the measured SAR is ≥0.8W/kg 2. Per KDB 865664 D01v01, 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.

FCC SAR Test Report Report No. : FA2N0801-03 14. Uncertainty Assessment The component of uncertainly may generally be categorized according to the methods used to evaluate them. The evaluation of uncertainly by the statistical analysis of a series of observations is termed a Type An evaluation of uncertainty. The evaluation of uncertainty by means other than the statistical analysis of a series of observation is termed a Type B evaluation of uncertainty. Each component of uncertainty, however evaluated, is represented by an estimated standard deviation, termed standard uncertainty, which is determined by the positive square root of the estimated variance. A Type A evaluation of standard uncertainty may be based on any valid statistical method for treating data. This includes calculating the standard deviation of the mean of a series of independent observations; using the method of least squares to fit a curve to the data in order to estimate the parameter of the curve and their standard deviations; or carrying out an analysis of variance in order to identify and quantify random effects in certain kinds of measurement. A type B evaluation of standard uncertainty is typically based on scientific judgment using all of the relevant information available. These may include previous measurement data, experience, and knowledge of the behavior and properties of relevant materials and instruments, manufacture’s specification, data provided in calibration reports and uncertainties assigned to reference data taken from handbooks. Broadly speaking, the uncertainty is either obtained from an outdoor source or obtained from an assumed distribution, such as the normal distribution, rectangular or triangular distributions indicated in Table 12.1 Uncertainty Distributions Normal Rectangular Triangular U-Shape (a) (b) Multi-plying Factor 1/k 1/√3 1/√6 1/√2 (a) standard uncertainty is determined as the product of the multiplying factor and the estimated range of variations in the measured quantity (b) κ is the coverage factor Table 12.1 Standard Uncertainty for Assumed Distribution The combined standard uncertainty of the measurement result represents the estimated standard deviation of the result. It is obtained by combining the individual standard uncertainties of both Type A and Type B evaluation using the usual “root-sum-squares” (RSS) methods of combining standard deviations by taking the positive square root of the estimated variances. Expanded uncertainty is a measure of uncertainty that defines an interval about the measurement result within which the measured value is confidently believed to lie. It is obtained by multiplying the combined standard uncertainty by a coverage factor. Typically, the coverage factor ranges from 2 to 3. Using a coverage factor allows the true value of a measured quantity to be specified with a defined probability within the specified uncertainty range. For purpose of this document, a coverage factor two is used, which corresponds to confidence interval of about 95 %. The DASY uncertainty Budget is shown in the following tables.
