4.2. SAR Measurement Procedure
4.2.1. Normal SAR Measurement Procedure
The following procedure shall be performed for each of the test conditions Measure the local SAR at a test point
within 8 mm of the phantom inner surface that is closest to the DUT.

a) Measure the two-dimensional SAR distribution within the phantom (area scan procedure).
b) The boundary of the measurement area shall not be closer than 20 mm from the phantom side walls. The
distance between the measurement points should enable the detection of the location of local maximum
with an accuracy of better than half the linear dimension of the tissue cube after interpolation. A maximum
grid spacing of 20 mm for frequencies below 3 GHz and (60/f [GHz]) mm for frequencies of 3 GHz and
greater is recommended. The maximum distance between the geometrical centre of the probe detectors
and the inner surface of the phantom shall be 5 mm for frequencies below 3 GHz and δ ln(2)/2 mm for
frequencies of 3 GHz and greater, where δ is the plane wave skin depth and ln(x) is the natural logarithm.
The maximum variation of the sensor-phantom surface distance shall be ± 1 mm for frequencies below
3 GHz and ± 0,5 mm for frequencies of 3 GHz and greater. At all measurement points the angle of the
probe with respect to the line normal to the surface should be less than 5°. If this cannot be achieved for
a measurement distance to the phantom inner surface shorter than the probe diameter, additional
uncertainty evaluation is needed.
c) From the scanned SAR distribution, identify the position of the maximum SAR value, in addition identify
the positions of any local maxima with SAR values within 2 dB of the maximum value that will not be
within the zoom scan of other peaks; additional peaks shall be measured only when the primary peak is
within 2 dB 6 of the SAR compliance limit (e.g., 1 W/kg for 1,6 W /kg 1 g limit, or 1,26 W/kg for 2 W /kg,
10 g limit).
d) Measure the three-dimensional SAR distribution at the local maxima locations identified in step c) (zoom
scan procedure). The horizontal grid step shall be (24 / f [GHz]) mm or less but not more than 8 mm. The
minimum zoom scan size is 30 mm by 30 mm by 30 mm for frequencies below 3 GHz. For higher
frequencies, the minimum zoom scan size can be reduced to 22 mm by 22 mm by 22 mm. The grid step
in the vertical direction shall be (8-f [GHz]) mm or less but not more than 5 mm, if uniform spacing is
used. If variable spacing is used in the vertical direction, the maximum spacing between the two closest
measured points to the phantom shell shall be (12/f [GHz]) mm or less but not more than 4 mm, and
the spacing between farther points shall increase by an incremental factor not exceeding 1,5. When
variable spacing is used, extrapolation routines shall be tested with the same spacing as used in
measurements. The maximum distance between the geometrical centre of the probe detectors and the
inner surface of the phantom shall be 5 mm for frequencies below 3 GHz and δ ln(2)/2 mm for
frequencies of 3 GHz and greater, where δ is the plane wave skin depth and ln(x) is the natural logarithm.
Separate grids shall be centred on each of the local SAR maxima found in step c). Uncertainties due to
field distortion between the media boundary and the dielectric enclosure of the probe should also be
minimized, which is achieved if the distance between the phantom surface and physical tip of the probe
is larger than probe tip diameter. Other methods may utilize correction procedures for these boundary
effects that enable high precision measurements closer than half the probe diameter. For all
measurement points, the angle of the probe with respect to the flat phantom surface shall be less than
5º.
e) Use post processing (e.g. interpolation and extrapolation) procedures to determine the local SAR values
at the spatial resolution needed for mass averaging.
f) The local SAR should be measured at the same location as in Step a). SAR drift is assessed
and reported in the uncertainty budget.
In the event that the evaluation of measurement drift exceeds the 5 % tolerance, it is required that SAR
be reassessed following guidelines contained within this standard.
If the drift is larger than 5 %, then the measurement drift shall be considered a bias, not an uncertainty.
A correction shall be applied to the measured SAR value. It is not necessary to record the drift in the
uncertainty budget (i.e. ui = 0 %). The uncertainty budget reported in a measurement report should
correspond to the highest SAR value reported (after correction, if applicable). Alternatively, the
uncertainty budget reported should cover all measurements, i.e., it should report a
conservative value.

5. Measurement Uncertainty
No measurement or test can ever be perfect and the imperfections give rise to error of measurement in the
results. Consequently, the result of a measurement is only an approximation to the value of the measurand
(the specific quantity subject to measurement) and is only complete when accompanied by a statement of the
uncertainty of the approximation.

The expression of uncertainty of a measurement result allows realistic comparison of results with reference
values and limits given in specifications and standards.
The uncertainty of the result may need to be taken into account when interpreting the measurement results.
The reported expanded uncertainties below are based on a standard uncertainty multiplied by an appropriate
coverage factor, such that a confidence level of approximately 95% is maintained. For the purposes of this
document “approximately” is interpreted as meaning “effectively” or “for most practical purposes”.
Confidence Calculated
Test Name Level Uncertainty

Uncertainty- Freq. < 3 GHz Body Configuration 1g 95 % ±19.22 %

Uncertainty- Freq. > 3 GHz Body Configuration 1g 95 % ±16.37 %

The methods used to calculate the above uncertainties are in line with those recommended within the various
measurement specifications. Where measurement specifications do not include guidelines for the evaluation of
measurement uncertainty, the published guidance of the appropriate accreditation body is followed.

9. Dielectric Property Measurements & System Check
9.1.Tissue Dielectric Parameters
The temperature of the tissue-equivalent medium used during measurement must also be within 18C to 25C
and within ± 2C of the temperature when the tissue parameters are characterized.
The dielectric parameters must be measured before the tissue-equivalent medium is used in a series of SAR
measurements. The parameters should be re-measured after each 3 – 4 days of use; or earlier if the dielectric
parameters can become out of tolerance; for example, when the parameters are marginal at the beginning of
the measurement series.
Tissue dielectric parameters were measured at the low, middle and high frequency of each operating frequency
range of the test device.

10. Measurements, Examinations and Derived Results
10.1. General Comments
SAR test was performed in accordance with the criteria in KDB 248227.
In the 2.4 GHz band, separate SAR procedures were applied to DSSS and OFDM configurations to
simplify DSSS test requirements. SAR test was evaluated on the mode with the highest rated power,
which is in this case was 802.11b mode. OFDM mode was not evaluated because when the highest
reported SAR for DSSS was adjusted by the ratio of OFDM to DSSS specified maximum output power,
the adjusted SAR obtained was < 1.2W/kg.
In the 5.0 GHz band, the initial test configuration transmission mode was determined by the 802.11
configuration with the highest maximum output power specified for production units, including upper
tune-up tolerance, in each standalone and aggregated frequency band. Since multiple channel
bandwidth configuration modes have the same specified maximum output power, SAR test was
performed on the largest channel bandwidth with the lowest order modulation.
For the cases where the power was not flat throughout the mode to test, additional runs were also
performed on the next highest bandwidth provided the power response was identical. This was
performed in order to assess the SAR response throughout the frequency band and establish that all
worst cases have been evaluated.

Note: SAR Values represented by “-“ indicate no SAR peaks were detected during area scans.

10.4. SAR Measurement Variability
In accordance with published RF Exposure KDB procedure 865664 D01 SAR measurement 100 MHz to 6 GHz.
These additional measurements are repeated after the completion of all measurements requiring the same
head or body tissue-equivalent medium in a frequency band. The test device should be returned to ambient
conditions (normal room temperature) with the battery fully charged before it is re-mounted on the device holder
for the repeated measurement(s) to minimize any unexpected variations in the repeated results.

1) Repeated measurement is not required when the original highest measured SAR is < 0.80 W/kg; steps 2)
through 4) do not apply.
2) When the original highest measured SAR is ≥ 0.80 W/kg, repeat that measurement once.
3) Perform a second repeated measurement only if the ratio of largest to smallest SAR for the original and first
repeated measurements is > 1.20 or when the original or repeated measurement is ≥ 1.45 W/kg (~ 10%
from the 1-g SAR limit).
4) Perform a third repeated measurement only if the original, first or second repeated measurement is ≥1.5
W/kg and the ratio of largest to smallest SAR for the original, first and second repeated measurements is >
1.20.

Note: SAR variability measurement not required as all measured 1g-SAR values are below 0.8 W/Kg.
