2. REQUIREMENTS FOR COMPLIANCE TESTING DEFINED BY THE
FCC
The US Federal Communications Commission has released the report and order “Guidelines for
Evaluating the Environmental Effects of RF Radiation", ET Docket No. 93-62 in August 1996 [1].
The order requires routine SAR evaluation prior to equipment authorization of portable
transmitter devices, including portable telephones. For consumer products, the applicable limit
is 1.6 mW/g as recommended by the ANSI/IEEE standard C95.1-1992 [6] for an uncontrolled
environment (Paragraph 65). According to the Supplement C of OET Bulletin 65 “Evaluating
Compliance with FCC Guide-lines for Human Exposure to Radio frequency Electromagnetic
Fields", released on Jun 29, 2001 by the FCC, the device should be evaluated at maximum
output power (radiated from the antenna) under “worst-case” conditions for normal or intended
use, incorporating normal antenna operating positions, device peak performance frequencies
and positions for maximum RF energy coupling.

$REPORT NO: 01U0933-1 DATE: SEPT 6, 2001 FCC ID: PUNDTP-800 EUT: CELLULAR CDMA WLL TERMINAL 3. DOSIMETRIC ASSESSMENT SETUP These measurements were performed with the automated near-field scanning system DASY3 from Schmid & Partner Engineering AG (SPEAG). The system is based on a high precision robot (working range greater than 0.9 m) which positions the probes with a positional repeatability of better than ± 0.02 mm. Special E- and H-field probes have been developed for measurements close to material discontinuity, the sensors of which are directly loaded with a Schottky diode and connected via highly resistive lines to the data acquisition unit. The system is described in detail in [3]. The SAR measurements were conducted with the dosimetric probe ET3DV6 SN: 1577 (manu- factured by SPEAG), designed in the classical triangular configuration [3] and optimized for dosimetric evaluation. The probe has been calibrated according to the procedure described in [7] with accuracy of better than ±10%. The spherical isotropy was evaluated with the procedure described in [8] and found to be better than ±0.25 dB. The phantom used was the \Generic Twin Phantom" described in [4]. The ear was simulated as a spacer of 4 mm thickness between the earpiece of the phone and the tissue simulating liquid. The Tissue simulation liquid used for each test is in according with the FCC OET65 supplement C as listed below.

5.3. SAR EVALUATION PROCEDURE

The evaluation was performed with the following procedure:

Step 1: Measurement of the SAR value at a fixed location above the ear point or central
position was used as a reference value for assessing the power drop.
Step 2: The SAR distribution at the exposed side of the head was measured at a distance
of 3.9 mm from the inner surface of the shell. The area covered the entire dimension of the
head or EUT and the horizontal grid spacing was 20 mm x 20 mm. Based on these data, the
area of the maximum absorption was determined by spline interpolation.
Step 3: Around this point, a volume of 32 mm x 32 mm x 34 mm was assessed by
measuring 5 x 5 x 7 points. On the basis of this data set, the spatial peak SAR value was
evaluated under the following procedure:
1. The data at the surface were extrapolated, since the center of the dipoles is 2.7 mm away
from the tip of the probe and the distance between the surface and the lowest measuring
point is 1.2 mm. The extrapolation was based on a least square algorithm [11]. A polynomial
of the fourth order was calculated through the points in z-axes. This polynomial was then
used to evaluate the points between the surface and the probe tip.
2. The maximum interpolated value was searched with a straightforward algorithm. Around
this maximum the SAR values averaged over the spatial volumes (1 g or 10 g) were
computed by the 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) [11], [12]. The
volume was integrated with the trapezoidal-algorithm. One thousand points (10 x 10 x 10)
were interpolated to calculate the average.
3. All neighboring volumes were evaluated until no neighboring volume with a higher average
value was found.
Step 4: Re-measurement of the SAR value at the same location as in Step 1. If the value
changed by more than 5%, the evaluation was repeated.
