4. Specific Absorption Rate (SAR)
4.1 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.
4.2 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,  T is the temperature rise and
related to the electrical field in the tissue by
Where:  is the conductivity of the tissue,
electrical field strength.


t is the exposure duration, or
is the mass density of the tissue and E is the RMS
However for evaluating SAR of low power transmitter, electrical field measurement is typically applied.

GHz with precision of better 30%.
5.4 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 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.
5.5 Other Test Equipment
5.5.1 Data Acquisition Electronics (DAE)
The data acquisition electronics consist of a highly sensitive electrometer-grade preamplifier with autozeroing, a channel and gain-switching multiplexer, a fast 16 bit AD-converter and a command decoder
with a control logic unit. Transmission to the measurement server is accomplished through an optical
downlink for data and status information, as well as an optical uplink for commands and the clock.
The mechanical probe mounting device includes two different sensor systems for frontal and sideways
probe contacts. They are used for mechanical surface detection and probe collision detection.
The input impedance of the DAE is 200 MOhm; the inputs are symmetrical and floating. Common mode
rejection is above 80 dB.
5.5.2 Robot
The SPEAG DASY system uses the high precision robots (DASY5: TX60XL) type from Stäubli SA
(France). For the 6-axis controller system, the robot controller version from Stäubli is used. The Stäubli
robot series have many features that are important for our application:
High precision (repeatability 0.02mm)
High reliability (industrial design)
Low maintenance costs (virtually maintenance free due to direct drive gears; no belt drives)
Jerk-free straight movements (brushless synchron motors; no stepper motors)
Low ELF interference (motor control fields shielded via the closed metallic construction shields)

5.5.3 Measurement Server
The Measurement server is based on a PC/104 CPU broad with CPU (DASY5: 400 MHz, Intel
Celeron), chip disk (DASY5: 128MB), RAM (DASY5: 128MB). The necessary circuits for
communication with the DAE electronic box, as well as the 16 bit AD converter system for optical
detection and digital I/O interface are contained on the DASY I/O broad, which is directly
connected to the PC/104 bus of the CPU broad.
Picture of Server for DASY 5
The measurement server performs all real-time data evaluation of field measurements and surface
detection, controls robot movements and handles safety operation. The PC operating system cannot
interfere with these time critical processes. All connections are supervised by a watchdog, and
disconnection of any of the cables to the measurement server will automatically disarm the robot and
disable all program-controlled robot movements. Furthermore, the measurement server is equipped
with an expansion port which is reserved for future applications. Please note that this expansion port
does not have a standardized pinout, and therefore only devices provided by SPEAG can be
connected. Devices from any other supplier could seriously damage the measurement server.
5.5.4 Device Holder for Phantom
The SAR in the phantom is approximately inversely proportional to the square of the distance between
the source and the liquid surface. For a source at 5mm distance, a positioning uncertainty of ±0.5mm
would produce a SAR uncertainty of ±20%. Accurate device positioning is therefore crucial for accurate
and repeatable measurements. The positions in which the devices must be measured are defined by
the standards.
The DASY device holder is designed to cope with the different positions given in the standard. It has
two scales for device rotation (with respect to the body axis) and device inclination (with respect to the
line between the ear reference points). The rotation centers for both scales are the ear reference point
(ERP). Thus the device needs no repositioning when changing the angles.
The DASY device holder is constructed of low-loss POM material having the following dielectric
parameters: relative permittivity=3 and loss tangent=0.02. The amount of dielectric material has been
reduced in the closest vicinity of the device, since measurements have suggested that the influence of
the clamp on the test results could thus be lowered.

The extension is lightweight and made of POM, acrylic glass and foam. It fits easily on the upper part of
the Mounting Device in place of the phone positioner. The extension is fully compatible with the TwinSAM and ELI phantoms.

5.6 Scanning Procedure
The DASY5 installation includes predefined files with recommended procedures for
measurements and validation. They are read-only document files and destined as fully defined
but unmeasured masks. All test positions (head or body-worn) are tested with the same
configuration of test steps differing only in the grid definition for the different test positions.
The “reference” and “drift” measurements are located at the beginning and end of the batch
process. They measure the field drift at one single point in the liquid over the complete procedure.
The indicated drift is mainly the variation of the DUT’s output power and should vary max. ± 5 %.
The “surface check” measurement tests the optical surface detection system of the DASY5 system
by repeatedly detecting the surface with the optical and mechanical surface detector and
comparing the results. The output gives the detecting heights of both systems, the difference
between the two systems and the standard deviation of the detection repeatability. Air bubbles or
refraction in the liquid due to separation of the sugar-water mixture gives poor repeatability (above
± 0.1mm). To prevent wrong results tests are only executed when the liquid is free of air bubbles.
The difference between the optical surface detection and the actual surface depends on the probe
and is specified with each probe. (It does not depend on the surface reflectivity or the probe angle
to the surface within ± 30°.)
Area Scan
The Area Scan is used as a fast scan in two dimensions to find the area of high field values before
running a detailed measurement around the hot spot. Before starting the area scan a grid spacing
is set according to FCC KDB Publication 865664. During scan the distance of the probe to the
phantom remains unchanged. After finishing area scan, the field maxima within a range of 2 dB
will be ascertained.
Zoom Scan
After the maximum interpolated values were calculated between the points in the cube, the SAR
was averaged over the spatial volume (1g or 10g) using a 3D-Spline interpolation algorithm. The
3D-spline is composed of three one-dimensional splines with the “Not a knot” condition (in x, y, and
z directions). The volume was then integrated with the trapezoidal algorithm.
Spatial Peak Detection
The procedure for spatial peak SAR evaluation has been implemented and can determine values
of masses of 1g and 10g, as well as for user-specific masses. The DASY5 system allows
evaluations that combine measured data and robot positions, such as:
• maximum search
• extrapolation
• boundary correction
• peak search for averaged SAR
During a maximum search, global and local maxima searches are automatically performed in 2-D
after each Area Scan measurement with at least 6 measurement points. It is based on the
evaluation of the local SAR gradient calculated by the Quadratic Shepard’s method. The algorithm
will find the global maximum and all local maxima within -2 dB of the global maxima for all SAR
distributions.
Extrapolation routines are used to obtain SAR values between the lowest measurement points and
the inner phantom surface. The extrapolation distance is determined by the surface detection
distance and the probe sensor offset. Several measurements at different distances are necessary
for the extrapolation. Extrapolation routines require at least 10 measurement points in 3-D space.
They are used in the Zoom Scan to obtain SAR values between the lowest measurement points
and the inner phantom surface. The routine uses the modified Quadratic Shepard’s method for
extrapolation.

5.7 Data Storage and Evaluation
5.7.1 Data Storage
The DASY5 software stores the acquired data from the data acquisition electronics as raw data (in
microvolt readings from the probe sensors), together with all necessary software parameters for the
data evaluation (probe calibration data, liquid parameters and device frequency and modulation data) in
measurement files with the extension “.DAE4”. The software evaluates the desired unit and format for
output each time the data is visualized or exported. This allows verification of the complete software
setup even after the measurement and allows correction of incorrect parameter settings. For example, if
a measurement has been performed with a wrong crest factor parameter in the device set up, the
parameter can be corrected afterwards and the data can be re-evaluated.
The measured data can be visualized or exported in different units or formats, depending on the
selected probe type ([V/m], [A/m], [°C], [mW/g], [mW/cm²], [dBrel], etc.). Some of these units are not
available in certain situations or show meaningless results, e.g., a SAR output in a loss less media will
always be zero. Raw data can also be exported to perform the evaluation with other software packages.
5.7.2 Data Evaluation by SEMCAD
The SEMCAD software automatically executes the following procedures to calculate the field units from
the microvolt readings at the probe connector. The parameters used in the evaluation are stored in the
configuration modules of the software:
Probe parameters: - Sensitivity
- Conversion factor
Normi, ai0, ai1, ai2
ConvFi
- Diode compression point
Dcpi
Device parameters: - Frequency
- Crest factor
cf
Media parameters: - Conductivity
- Density
These parameters must be set correctly in the software. They can be found in the component
documents or they can be imported into the software from the configuration files issued for the DASY5
components. In the direct measuring mode of the multimeter option, the parameters of the actual

system setup are used. In the scan visualization and export modes, the parameters stored in the
corresponding document files are used.
The first step of the evaluation is a linearization of the filtered input signal to account for the
compression characteristics of the detector diode. The compensation depends on the input signal, the
diode type and the DC-transmission factor from the diode to the evaluation electronics.
If the exciting field is pulsed, the crest factor of the signal must be known to correctly compensate for
peak power. The formula for each channel can be given as:
Vi = Ui + Ui2 ·c f / dcpi
With Vi = compensated signal of channel i ( i = x, y, z )
Ui = input signal of channel i ( i = x, y, z )
cf = crest factor of exciting field (DASY parameter)
dcpi = diode compression point (DASY parameter)
From the compensated input signals the primary field data for each channel can be
evaluated:
E-field probes: Ei = ( Vi / Normi ·ConvF )1/2
H-field probes: Hi = ( Vi )1/2 ·( ai0 + ai1 f + ai2f2 ) / f
With Vi = compensated signal of channel i (i = x, y, z)
Normi = sensor sensitivity of channel i (i = x, y, z)
[mV/(V/m)2] for E-field Probes
ConvF = sensitivity enhancement in solution
aij = sensor sensitivity factors for H-field probes
f = carrier frequency [GHz]
Ei = electric field strength of channel i in V/m
Hi = magnetic field strength of channel i in A/m
The RSS value of the field components gives the total field strength (Hermitian magnitude):
Etot = (Ex2+ EY2+ Ez2)1/2
The primary field data are used to calculate the derived field units.
SAR = (Etot) 2 · σ / (ρ· 1000)
with SAR = local specific absorption rate in mW/g
Etot = total field strength in V/m
= conductivity in [mho/m] or [Siemens/m]
= equivalent tissue density in g/cm 3
Note that the density is normally set to 1 (or 1.06), to account for actual brain density rather than
the density of the simulation liquid. The power flow density is calculated assuming the excitation
field to be a free space field.
Ppwe = Etot2 / 3770 or Ppwe = Htot2 ·37.7
with Ppwe = equivalent power density of a plane wave in mW/cm 2
Etot = total electric field strength in V/m; Htot = total magnetic field strength in A/m

The head tissue dielectric parameters recommended by the IEEE SCC-34/SC-2 in P1528 have been
incorporated in the following table. These head parameters are derived from planar layer models
simulating the highest expected SAR for the dielectric properties and tissue thickness variations in a
human head. Other head and body tissue parameters that have not been specified in P1528 are
derived from the tissue dielectric parameters computed from the 4-Cole-Cole equations described in
Reference [12] and extrapolated according to the head parameters specified in P1528.

7. SAR Measurement Evaluation
7.1 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.
7.2 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. EUT Testing Position
The DUT is tested using a Wireless communications tester as controller unit to set test channels and
maximum output power to the DUT, as well as for measuring the conducted peak power.
8.1 Test Positions Configuration
8.1.1
General considerations
(a) The vertical centerline passes through two points on the front side of the handset - the midpoint of
the width wt of the handset at the level of the acoustic output, and the midpoint of the width w b of the
bottom of the handset.
(b) The horizontal line is perpendicular to the vertical centerline and passes through the center of the
acoustic output. The horizontal line is also tangential to the face of the handset at point A.
(c) The two lines intersect at point A. Note that for many handsets, point A coincides with the center of
the acoustic output; however, the acoustic output may be located elsewhere on the horizontal line. Also
note that the vertical centerline is not necessarily parallel to the front face of the handset, especially for
clamshell handsets, handsets with flip covers, and other irregularly shaped handsets.

Cheek Position
(a) To position the device with the vertical center line of the body of the device and the horizontal line
crossing the center piece in a plane parallel to the sagittal plane of the phantom. While maintaining the
device in this plane, align the vertical center line with the reference plane containing the three ear and
mouth reference point (M: Mouth, RE: Right Ear, and LE: Left Ear) and align the center of the ear piece
with the line RE-LE.
(b) To move the device towards the phantom with the ear piece aligned with the line LE-RE until the
phone touched the ear. While maintaining the device in the reference plane and maintaining the phone

8.1.3
Tilted Position
(a) To position the device in the “cheek” position described above.
(b) While maintaining the device the reference plane described above and pivoting against the ear,
moves it outward away from the mouth by an angle of 15 degrees or until contact with the ear is lost.
Illustration for Tilted Position
8.1.4
Body Worn Position
Body-worn operating configurations are tested with the holder attached to the device and positioned
against a flat phantom with test separation distance of 0mm in a normal user configuration. Devices that
are designed to operate in front of a person’s face, as in oush-to-tak configurations, are tested for SAR
compliance with the front of the device positioned to face the flat phantom in head liquid. For devices
that are carried next to the body such as a shoulder, waist or chest-worn transmitters, SAR comlicance
is tested with the accessories, including headsets and microphones, attached to the device and
positioned against a flat phantom in a normal use configuration.

further SAR exclusion.
2. SAR is not required for 802.11g/n when
a) KDB Publication 447498 D01 SAR test exclusion applies to the OFDM configuration.
b) 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 W/kg.
3. Each channel should be tested at the lowest data rate, and repeated SAR measurement is required
only when the measured SAR is ≥ 0.8 W/kg.
4. 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.

9.3 Simultaneous Transmission SAR Analysis
Since the 2.4GHz and Bluetooth use the same one ant and cann’t transmit simultaneously, hence the
simultaneous transmission SAR is not applicable.

10. Measurement Uncertainty
The component of uncertainly may generally be categorized according to the methods used to evaluate
them. The evaluation of uncertainly by the statistical analysis of a series of observations is termed a
Type An evaluation of uncertainty. The evaluation of uncertainty by means other than the statistical
analysis of a series of observation is termed a Type B evaluation of uncertainty. Each component of
uncertainty, however evaluated, is represented by an estimated standard deviation, termed standard
uncertainty, which is determined by the positive square root of the estimated variance.
A Type A evaluation of standard uncertainty may be based on any valid statistical method for treating
data. This includes calculating the standard deviation of the mean of a series of independent
observations; using the method of least squares to fit a curve to the data in order to estimate the
parameter of the curve and their standard deviations; or carrying out an analysis of variance in order to
identify and quantify random effects in certain kinds of measurement.
A type B evaluation of standard uncertainty is typically based on scientific judgment using all of the
relevant information available. These may include previous measurement data, experience, and
knowledge of the behavior and properties of relevant materials and instruments, manufacture’s
specification, data provided in calibration reports and uncertainties assigned to reference data taken
from handbooks. Broadly speaking, the uncertainty is either obtained from an outdoor source or
obtained from an assumed distribution, such as the normal distribution, rectangular or triangular
distributions indicated in table below.

Normal
Rectangluar
Triangular
U-Shape
Multi-plying Factor(a)
1/K(b)
1/√3
1/√6
1/√2
(a) standard uncertainty is determined as the product of the multiplying factor and the estimated range
of variations in the measured quantity
(b) K is the coverage factor
The combined standard uncertainty of the measurement result represents the estimated standard
deviation of the result. It is obtained by combining the individual standard uncertainties of both Type A
and Type B evaluation using the usual “root-sum-squares” (RSS) methods of combining standard
deviations by taking the positive square root of the estimated variances.
Expanded uncertainty is a measure of uncertainty that defines an interval about the measurement result
within which the measured value is confidently believed to lie. It is obtained by multiplying the combined
standard uncertainty by a coverage factor. Typically, the coverage factor ranges from 2 to 3. Using a
coverage factor allows the true value of a measured quantity to be specified with a defined probability
within the specified uncertainty range. For purpose of this document, a coverage factor two is used,
which corresponds to confidence interval of about 95 %. The DASY uncertainty Budget is shown in the
following tables.
