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
    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 is expressed in units of Watts per kilogram (W/kg)

                                                              𝛔|𝐄|𝟐

6. System Description and Setup
The DASY system used for performing compliance tests consists of the following items:




     A standard high precision 6-axis robot with controller, teach pendant and software. An arm extension for
      accommodating the data acquisition electronics (DAE).
     An isotropic Field probe optimized and calibrated for the targeted measurement.
     A data acquisition electronics (DAE) which performs the signal amplification, signal multiplexing,
      AD-conversion, offset measurements, mechanical surface detection, collision detection, etc. The unit is
      battery powered with standard or rechargeable batteries. The signal is optically transmitted to the EOC.
     The Electro-optical converter (EOC) performs the conversion from optical to electrical signals for the
      digital communication to the DAE. To use optical surface detection, a special version of the EOC is
      required. The EOC signal is transmitted to the measurement server.
     The function of the measurement server is to perform the time critical tasks such as signal filtering,
      control of the robot operation and fast movement interrupts.
     The Light Beam used is for probe alignment. This improves the (absolute) accuracy of the probe
      positioning.
     A computer running WinXP or Win7 and the DASY5 software.
     Remote control and teach pendant as well as additional circuitry for robot safety such as warning lamps,
      etc.
     The phantom, the device holder and other accessories according to the targeted measurement.

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.

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.

10. Conducted RF Output Power (Unit: dBm)
<WLAN Conducted Power>
General Note:
1.  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.

  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: 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.
  4.   The device only supports MIMO operation.



  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 S 1.2 Wikg
  2.   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.
  3.   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.
  4.   During SAR testing the WLAN transmission was verified using a spectrum analyzer.

          General Note:
          1.   Per KDB 865664 DO1v01r04, for each frequency band, repeated SAR measurement is required only when the
               measured SAR is 20.8W/kg.
          2.   Per KDB 865664 DO1v01104, if the ratio among the repeated measurement is < 1.2 and the measured SAR
               <1.45Wi/kg, only one repeated measurementis 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. : FA940808
13. 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.
