8. Dielectric Property Measurements & System Check
8.1. Dielectric Property Measurements
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. Measured and Reported (Scaled) SAR Results
SAR Test Reduction criteria are as follows:

KDB 447498 D01 General RF Exposure Guidance v05r02:
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

KDB 248227 D01 SAR meas for 802.11 v02r01:
SAR test reduction for 802.11 Wi-Fi transmission mode configurations are considered separately for DSSS and OFDM. An initial
test position is determined to reduce the number of tests required for certain exposure configurations with multiple test positions.
An initial test configuration is determined for each frequency band and aggregated band according to maximum output power,
channel bandwidth, wireless mode configurations and other operating parameters to streamline the measurement requirements.
For 2.4 GHz DSSS, either the initial test position or DSSS procedure is applied to reduce the number of SAR tests; these are
mutually exclusive. For OFDM, an initial test position is only applicable to next to the ear, UMPC mini-tablet and hotspot mode
configurations, which is tested using the initial test configuration to facilitate test reduction. For other exposure conditions with a
fixed test position, SAR test reduction is determined using only the initial test configuration.
The multiple test positions require SAR measurements in head, hotspot mode or UMPC mini-tablet configurations may be
reduced according to the highest reported SAR determined using the initial test position(s) by applying the DSSS or OFDM SAR
measurement procedures in the required wireless mode test configuration(s). The initial test position(s) is measured using the
highest measured maximum output power channel in the required wireless mode test configuration(s). When the reported SAR
for 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
wireless mode combination within the frequency band or aggregated band. DSSS and OFDM configurations are
considered separately according to the required SAR procedures.
• > 0.4 W/kg, SAR is repeated using the same wireless mode test 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 reported SAR is ≤ 0.8 W/kg or all required test positions are tested.
o For subsequent test positions with equivalent test separation distance or when exposure is dominated by coupling
conditions, the position for maximum coupling condition should be tested.
o When it is unclear, all equivalent conditions must be tested.
• For all positions/configurations tested using the initial test position and subsequent test positions, when the reported
SAR is > 0.8 W/kg, measure the SAR for these positions/configurations on the subsequent next highest measured
output power channel(s) until the reported SAR is ≤ 1.2 W/kg or all required test channels are considered.
o The additional power measurements required for this step should be limited to those necessary for identifying
subsequent highest output power channels to apply the test reduction.
• When the specified maximum output power is the same for both UNII 1 and UNII 2A, begin SAR measurements in UNII
2A with the channel with the highest measured output power. If the reported SAR for UNII 2A is ≤ 1.2 W/kg, SAR is not
required for UNII 1; otherwise treat the remaining bands separately and test them independently for SAR.
• When the specified maximum output power is different between UNII 1 and UNII 2A, begin SAR with the band that has
the higher specified maximum output. If the highest reported SAR for the band with the highest specified power is ≤
1.2 W/kg, testing for the band with the lower specified output power is not required; otherwise test the remaining bands
independently for SAR.

To determine the initial test position, Area Scans were performed to determine the position with the Maximum Value of SAR
(measured). The position that produced the highest Maximum Value of SAR is considered the worst case position; thus used as
the initial test position.

11. SAR Measurement Variability
In accordance with published RF Exposure KDB 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 <1.6 or 2 W/kg (1-g or 10-g
respectively); steps 2) through 4) do not apply.
2) When the original highest measured SAR is ≥ 0.8 or 2 W/kg (1-g or 10-g respectively), 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 3 (1-g or 10-g respectively) or when the original or repeated measurement
is ≥ 1.45 or 3.6 W/kg (~ 10% from the 1-g or 10-g respective SAR limit).
4) Perform a third repeated measurement only if the original, first, or second repeated measurement is ≥ 1.5 or
3.75 W/kg (1-g or 10-g respectively) and the ratio of largest to smallest SAR for the original, first and second
repeated measurements is > 1.20 or 3 (1-g or 10-g respectively).
