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 =       (   )= (    )

   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

                                                               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 =

   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.

5.6 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.

   <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.

5.7 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 measurement files. 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/m], [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                         Normi, ai0, ai1, ai2
                                     - Conversion factor                   ConvFi
                                     - Diode compression point             dcpi
       Device parameters:            - Frequency                           f
                                     - Crest factor                        cf
       Media parameters:             - Conductivity                        σ
                                     - Density                             ρ
      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 document files are used.
      The first step of the evaluation is a linearization of the filtered 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.

Note:
 1.   The calibration certificate of DASY can be referred to appendix C of this report.
 2.   The Insertion Loss calibration of Dual Directional Coupler and Attenuator were characterized via the network
      analyzer and compensated during system check.
 3.   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
 4.   Attenuator 1 insertion loss is calibrated by the network Analyzer, which the calibration is valid, before system
      check.

6. Tissue Simulating Liquids
   For the measurement of the field distribution inside the SAM phantom with DASY, the phantom must be filled with
   around 25 liters of homogeneous body tissue simulating liquid. For head SAR testing, the liquid height from the ear
   reference point (ERP) of the phantom to the liquid top surface is larger than 15 cm, which is shown in Fig. 6.1. For
   body SAR testing, the liquid height from the center of the flat phantom to the liquid top surface is larger than 15 cm,
   which is shown in Fig. 6.2.

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. The equipment setup is shown below:

8. EUT Testing Position
    Please refer to Appendix D for the test setup photos.

9. 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


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.


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 D01v01r01 quoted below.
    When the 1-g SAR of the highest peak is within 2 dB of the SAR limit, additional zoom scans are required for other
    peaks within 2 dB of the highest peak that have not been included in any zoom scan to ensure there is no increase in
    SAR.

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.

Note:
1.    Per KDB 248227 D01 v01r02, choose the highest output power channel to test SAR and determine further SAR
      exclusion.
2.    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 1/4dB higher than those measured at
      the lowest data rate.
3.    Apply the test exclusion rule in KDB 248227 D01 v01r02 11g, 11n-HT20/HT40 output power is less than 1/4dB
      higher than 11b mode, thus the SAR can be excluded.

Note:
1. Maximum power is the source-based time-average power and represents the maximum RF output power among
   production units
2. Per KDB 447498 D01v05r01, for larger devices, the test separation distance of adjacent edge configuration is
   determined by the closest separation between the antenna and the user.
3. Per KDB 447498 D01v05r01, standalone SAR test exclusion threshold is applied; If the distance of the antenna to the
   user is < 5mm, 5mm is used to determine SAR exclusion threshold
4. Per KDB 447498 D01v05r01, the 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation
   distances ≤ 50 mm are determined by:
      [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(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
5. Per KDB 447498 D01v05r01, at 100 MHz to 6 GHz and for test 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

       12. SAR Test Results
       Note:
       1. Per KDB 447498 D01v05r01, 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 WLAN: Reported SAR(W/kg)= Measured SAR(W/kg)*Tune-up Scaling Factor
       2. Per KDB 447498 D01v05r01, 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 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
       3. Per KDB 616217 D04v01r01, the additional separation introduced by the contour against a flat phantom is > 5 mm on this
           device and reported SAR is > 1.2 W/kg, a curved or contoured back surface or edge SAR is required, more detail
           information please refer to the setup photo.
       4. For SAR testing of the curved region of the device, the device was placed directly against the phantom at the point where
           the distance between the antenna and device exterior is a minimum.

       Note:
       1. Per KDB 865664 D01v01r01, for each frequency band, repeated SAR measurement is required only when the
           measured SAR is ≥0.8W/kg
       2. Per KDB 865664 D01v01r01, 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.

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 14.1

   (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 14.1. 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.
