Model: CM-43438-V1 3. Specific Absorption Rate (SAR) 3.1 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 techiques 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. 3.2 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 (  ). The equation description is as below: SAR is expressed in units of Watts per kilogram (W/kg) SAR measurement can be either related to the temperature elevation in tissue by Where: C is the specific heat capacity,  T is the temperature rise and  t is the exposure duration, or related to the electrical field in the tissue by Where:  is the conductivity of the tissue,  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. REPORT NO.: STR16078090H Page 7 of 38 SAR REPORT

Model: CM-43438-V1 4. SAR Measurement System 4.1 The Measurement System Comosar is a system that is able to determine the SAR distribution inside a phantom of human being according to different standards. The Comosar system consists of the following items: - Main computer to control all the system - 6 axis robot - Data acquisition system - Miniature E-field probe - Phone holder - Head simulating tissue The following figure shows the system. The EUT under test operating at the maximum power level is placed in the phone holder, under the phantom, which is filled with head simulating liquid. The E-Field probe measures the electric field inside the phantom. The OpenSAR software computes the results to give a SAR value in a 1g or 10g mass. 4.2 Probe For the measurements the Specific Dosimetric E-Field Probe SSE5 SN 09/13 EP168 with following specifications is used - Dynamic range: 0.01-100 W/kg - Probe Length: 330 mm - Length of Individual Dipoles: 4.5 mm - Maximum external diameter: 8 mm - Probe Tip External Diameter : 5 mm - Distance between dipoles / probe extremity: 2.7mm REPORT NO.: STR16078090H Page 8 of 38 SAR REPORT

Model: CM-43438-V1 - Probe linearity: ＜0.25 dB - Axial Isotropy: ＜0.25 dB - Spherical Isotropy: ＜0.50 dB - Calibration range: 700 to 3000MHz for head & body simulating liquid. Angle between probe axis (evaluation axis) and suface normal line:1ess than 30° Probe calibration is realized, in compliance with EN 62209-1 and IEEE 1528 STD, with CALISAR, Antennessa proprietary calibration system. The calibration is performed with the EN 62209-1 annexe technique using reference guide at the five frequencies. Where : Pfw = Forward Power Pbw = Backward Power a and b =Waveguide dimensions I = Skin depth Keithley configuration: Rate = Medium; Filter = ON; RDGS = 10; Filter type = Moving Average; Range auto after each calibration, a SAR measurement is performed on a validation dipole and compared with a NPL calibrated probe, to verify it. REPORT NO.: STR16078090H Page 9 of 38 SAR REPORT

Model: CM-43438-V1 The calibration factors, CF(N), for the 3 sensors corresponding to dipole 1, dipole 2 and dipole 3 are: CF(N)=SAR(N)/Vlin(N) (N=1,2,3) The linearised output voltage Vlin(N) is obtained from the displayed output voltage V(N) using Vlin(N)=V(N)*(1+V(N)/DCP(N)) (N=1,2,3) where DCP is the diode compression point in mV. 4.3 Probe Calibration Process Dosimetric Assessment Procedure Each E-Probe/Probe Amplifier combination has unique calibration parameters. SATIMO Probe calibration procedure is conducted to determine the proper amplifier settings to enter in the probe parameters. The amplifier settings are determined for a given frequency by subjecting the probe to a known E-field density (1 mW/cm2) using an with CALISAR, Antenna proprietary calibration system. Free Space Assessment Procedure The free space E-field from amplified probe outputs is determined in a test chamber. This calibration can be performed in a TEM cell if the frequency is below 1 GHz and in a waveguide or other methodologies above 1 GHz for free space. For the free space calibration, the probe is placed in the volumetric center of the cavity and at the proper orientation with the field. The probe is rotated 360 degrees until the three channels show the maximum reading. The power density readings equates to 1mW/cm2. Temperature Assessment Procedure E-field temperature correlation calibration is performed in a flat phantom filled with the appropriate simulated head tissue. The E-field in the medium correlates with the temperature rise in the dielectric medium. For temperature correlation calibration a RF transparent thermistor-based temperature probe is used in conjunction with the E-field probe. SAR is proportional to ΔT/Δt, the initial rate of tissue heating, before thermal diffusion takes place. The electric field in the simulated tissue can be used to estimate SAR by equating the thermally derived SAR to that with the E- field component. REPORT NO.: STR16078090H Page 10 of 38 SAR REPORT

Model: CM-43438-V1 6. SAR Measurement Evaluation 6.1 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. 6.2 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 which comes from a signal generator at frequency 835 MHz and 1900 MHz. 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.

REPORT NO.: STR16078090H Page 19 of 38 SAR REPORT

Model: CM-43438-V1 8. SAR Measurement Procedures 8.1 Measurement Procedures The measurement procedures are as follows: (a) Use base station simulator (if applicable) or engineering software to transmit RF power continuously (continuous Tx) in the highest power channel. (b) Keep EUT to radiate maximum output power or 100% factor (if applicable) (c) Measure output power through RF cable and power meter. (d) Place the EUT in the positions as Annex E demonstrates. (e) Set scan area, grid size and other setting on the SATIMO software. (f) Measure SAR results for the highest power channel on each testing position. (g) Find out the largest SAR result on these testing positions of each band (h) Measure SAR results for other channels in worst SAR testing position if the 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 8.2 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 SATIMO 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. 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 (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 3D 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 REPORT NO.: STR16078090H Page 20 of 38 SAR REPORT

Model: CM-43438-V1 8.3 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 measures 5x5x7 points with step size 8, 8 and 5 mm for 300 MHz to 3 GHz, and 8x8x8 points with step size 4, 4 and 2.5 mm for 3 GHz to 6 GHz. The Zoom Scan is performed around the highest E-field value to determine the averaged SAR-distribution over 10 g. 8.4 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 (step-size is 4, 4 and 2.5 mm). When all volume scan were completed, the software can combine and subsequently superpose these measurement data to calculating the multiband SAR. 8.5 SAR Averaged Methods The local SAR inside the phantom is measured using small dipole sensing elements inside a probe body. The probe tip must not be in contact with the phantom surface in order to minimize measurements errors, but the highest local SAR will occur at the surface of the phantom. An extrapolation is using to determinate this highest local SAR values. The extrapolation is based on a fourth-order least-square polynomial fit of measured data. The local SAR value is then extrapolated from the liquid surface with a 1mm step. The measurements have to be performed over a limited time (due to the duration of the battery) so the step of measurement is high. It could vary between 5 and 8 mm. To obtain an accurate assessment of the maximum SAR averaged over 10g and 1 g requires a very fine resolution in the three dimensional scanned data array. 8.6 Power Drift Monitoring All SAR testing is under the EUT install full charged battery and transmit maximum output power. In SATIMO 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 drift more than 5%, the SAR will be retested. REPORT NO.: STR16078090H Page 21 of 38 SAR REPORT

Per KDB 248227 D01 v02r02, if 11g and 11n average output power is higher than 1/4 dB higher than 11b mode, SAR will be verified. 3. For each frequency band, testing at higher data rates and higher order modulations is not required when the maximum average output power for each of these configurations is less than 1/4 dB higher than those measured at the lowest data rate.
