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.

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

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

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.

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.

General Note:
 1.  Prior to system verification and validation, the path loss from the signal generator to the system check source and
     the power meter, which includes the amplifier, cable, attenuator and directional coupler, was measured by the
     network analyzer. The reading of the power meter was offset by the path loss difference between the path to the
     power meter and the path to the system check source to monitor the actual power level fed to the system check
     source.

9. System Verification
9.1 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. 10.1. 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. 10.2.

         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.

   <SAR test exclusion table>
  General Note:
  1. 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

  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.   During SAR testing the WLAN transmission was verified using a spectrum analyzer.

          General Note:
          1. 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.

                 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.

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.
