3. Specific Absorption Rate (SAR)
3.1 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 techiques 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.
3.2 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 (  ). The equation description is as
below:
SAR is expressed in units of Watts per kilogram (W/kg)
SAR measurement can be either related to the temperature elevation in tissue by
Where: C is the specific heat capacity,
the
electrical field in the tissue by
Where:
 T is the temperature rise and  t is the exposure duration, or related to
 is the conductivity of the tissue,  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.

The calibration factors, CF(N), for the 3 sensors corresponding to dipole 1, dipole 2 and dipole 3 are:
CF(N)=SAR(N)/Vlin(N) (N=1,2,3)
The linearised output voltage Vlin(N) is obtained from the displayed output voltage V(N) using
Vlin(N)=V(N)*(1+V(N)/DCP(N)) (N=1,2,3)
where DCP is the diode compression point in mV.
4.3 Probe Calibration Process
Dosimetric Assessment Procedure
Each E-Probe/Probe Amplifier combination has unique calibration parameters. SATIMO Probe calibration
procedure is conducted to determine the proper amplifier settings to enter in the probe parameters. The amplifier
settings are determined for a given frequency by subjecting the probe to a known E-field density (1 mW/cm2)
using an with CALISAR, Antenna proprietary calibration system.
Free Space Assessment Procedure
The free space E-field from amplified probe outputs is determined in a test chamber. This calibration can be
performed in a TEM cell if the frequency is below 1 GHz and in a waveguide or other methodologies above 1
GHz for free space. For the free space calibration, the probe is placed in the volumetric center of the cavity and at
the proper orientation with the field. The probe is rotated 360 degrees until the three channels show the maximum
reading. The power density readings equates to 1mW/cm2.
Temperature Assessment Procedure
E-field temperature correlation calibration is performed in a flat phantom filled with the appropriate simulated
head tissue. The E-field in the medium correlates with the temperature rise in the dielectric medium. For
temperature correlation calibration a RF transparent thermistor-based temperature probe is used in conjunction
with the E-field probe.
SAR is proportional to ΔT/Δt, the initial rate of tissue heating, before thermal diffusion takes place. The electric
field in the simulated tissue can be used to estimate SAR by equating the thermally derived SAR to that with the
E- field component.

4.4 Phantom
For the measurements the Specific Anthropomorphic Mannequin (SAM) defined by the IEEE SCC-34/SC2 group
is used. The phantom is a polyurethane shell integrated in a wooden table. The thickness of the phantom amounts
to 2mm +/- 0.2mm. It enables the dosimetric evaluation of left and right phone usage and includes an additional
flat phantom part for the simplified performance check. The phantom set-up includes a cover, which prevents the
evaporation of the liquid.

6. SAR Measurement Evaluation
6.1 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.
6.2 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 which comes from a signal generator at frequency 835 MHz and 1900 MHz. 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.

8. SAR Measurement Procedures
8.1 Measurement Procedures
The measurement procedures are as follows:
(a) Use base station simulator (if applicable) or engineering software to transmit RF power continuously
(continuous Tx) in the highest power channel.
(b) Keep EUT to radiate maximum output power or 100% factor (if applicable)
(c) Measure output power through RF cable and power meter.
(d) Place the EUT in the positions as Annex D demonstrates.
(e) Set scan area, grid size and other setting on the SATIMO software.
(f) Measure SAR results for the highest power channel on each testing position.
(g) Find out the largest SAR result on these testing positions of each band
(h) Measure SAR results for other channels in worst SAR testing position if the 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
8.2 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 SATIMO 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. 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
(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 3D 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
REPORT NO.: STR16108134H
Page 21 of 98
SAR REPORT
Model: LJ-C2
8.3 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
measures 5x5x7 points with step size 8, 8 and 5 mm for 300 MHz to 3 GHz, and 8x8x8 points with step size 4, 4
and 2.5 mm for 3 GHz to 6 GHz. The Zoom Scan is performed around the highest E-field value to determine the
averaged SAR-distribution over 10 g.
8.4 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 (step-size is 4, 4 and 2.5 mm). When all volume scan
were completed, the software can combine and subsequently superpose these measurement data to calculating the
multiband SAR.
8.5 SAR Averaged Methods
The local SAR inside the phantom is measured using small dipole sensing elements inside a probe body. The
probe tip must not be in contact with the phantom surface in order to minimize measurements errors, but the
highest local SAR will occur at the surface of the phantom.
An extrapolation is using to determinate this highest local SAR values. The extrapolation is based on a
fourth-order least-square polynomial fit of measured data. The local SAR value is then extrapolated from the
liquid surface with a 1mm step.
The measurements have to be performed over a limited time (due to the duration of the battery) so the step of
measurement is high. It could vary between 5 and 8 mm. To obtain an accurate assessment of the maximum SAR
averaged over 10g and 1 g requires a very fine resolution in the three dimensional scanned data array.
8.6 Power Drift Monitoring
All SAR testing is under the EUT install full charged battery and transmit maximum output power. In SATIMO
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 drift more than 5%, the SAR will be retested.

Note: The source-based time-averaged power is linearly scaled the maximum burst averaged power based on
time slots. The calculated method are shown as below:
Source based time-average power = Burst averaged power - Duty cycle factor in dB
Remark:
1. For Body SAR testing, GPRS should be evaluated, therefore the EUT was set in GPRS (4Tx slots) for GSM850 and
GPRS (3Tx slots) for GSM1900 due to its highest source-based time-average power.
2. Per KDB 447498 D01 v06, the maximum output power channel is used for SAR testing and for further SAR test
reduction.
3. The DUT do not support DTM function.

Remark:
1. Per KDB 248227 D01 v02r02, For 802.11b DSSS SAR measurements, DSSS SAR procedure applies to fixed
exposure test position and initial test position procedure applies to multiple exposure test positions.
2. Per KDB 248227 D01 v02r02, For 802.11b DSSS SAR measurements ,when the reported SAR of the highest
measured maximum output power channel (see 3.1) for the exposure configuration is ≤ 0.8 W/kg, no further SAR testing
is required for 802.11b DSSS in that exposure configuration. When the reported SAR is > 0.8 W/kg, SAR is required for
that exposure configuration using the next highest measured output power channel. When any reported SAR is > 1.2
W/kg, SAR is required for the third channel; i.e., all channels require testing.
3 .For OFDM modes (802.11g/n), SAR is not required when the highest reported SAR for DSSS is adjusted by the ratio of
OFDM to DSSS specified maximum output power and it is <= 1.2W/kg.

Remark:
1. Per KDB941225 D05 v02r05, Start with the largest channel bandwidth then measure SAR for QPSK with 1 RB
allocation, using the RB offset and required test channel combination with the highest maximum output power among RB
offsets at the upper edge, middle, and lower edge of each required test channel. When the reported SAR is≤ 0.8 W/kg,
testing of the remaining RB offset configurations and required test channels is not required for 1 RB allocation; otherwise,
SAR is required for the remaining required test channels and only for the RB offset configuration with the highest output
power for that channel. 6 When the reported SAR of a required test channel is > 1.45 W/kg, SAR is required for all three
RB offset configurations for that required test channel.
2. Per KDB941225 D05 v02r05, The procedures required for 1 RB allocation in 5.2.1 are applied to measure the SAR for
QPSK with 50% RB allocation.
3. Per KDB941225 D05 v02r05, For QPSK with 100% RB allocation, SAR is not required when the highest maximum
output power for 100 % RB allocation is less than the highest maximum output power in 50% and 1 RB allocations, and
the highest reported SAR for 1 RB and 50% RB allocation in 5.2.1 and 5.2.2 are ≤ 0.8 W/kg. Otherwise, SAR is
measured for the highest output power channel; and if the reported SAR is > 1.45 W/kg, the remaining required test
channels must also be tested.
4. Per KDB941225 D05 v02r05, For each modulation besides QPSK; e.g., 16-QAM, 64-QAM, apply the QPSK procedures
in 5.2.1, 5.2.2, and 5.2.3 to determine the QAM configurations that may need SAR measurement. For each configuration
identified as required for testing, SAR is required only when the highest maximum output power for the configuration in the
higher order modulation is > ½ dB higher than the same configuration in QPSK or when the reported SAR for the QPSK
configuration is > 1.45 W/kg.

Remark:
Bluetooth maximum output power is -0.722dBm, and Tune-Up output power is 0dBm. Per KDB 447498 D01 v06, 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,16 where
- f(GHz) is the RF channel transmit frequency in GHz
- Power and distance are rounded to the nearest mW and mm before calculation17
- The result is rounded to one decimal place for comparison

Remark:
1. GSM and WCDMA share the same antenna, and cannot transmit simultaneously.
2. WLAN and Bluetooth share the same antenna, and cannot transmit simultaneously.
3. According to the KDB 447498 D01 v06, when standalone SAR test exclusion applies to an antenna that transmits
simultaneously with other antennas, the standalone SAR must be estimated according to following to determine
simultaneous transmission SAR test exclusion:
(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]·[√f(GHz)/x] W/kg for test
separation distances ≤ 50 mm;
where x = 7.5 for 1-g SAR, and x = 18.75 for 10-g SAR.
For simultaneous transmission analysis, Bluetooth SAR is estimated per KDB 447498 D01 v06 as below:
Bluetooth:

(mW)

Distance (mm)
Frequency (GHz)

0.0208
4. The maximum SAR summation is calculated based on the same configuration and test position.
