SAR COMPLIANCE TESTING OF ATHEROS COMMUNICATIONS MODEL AR5BCB-00013 CARDBUS CARD INSERTED INTO A LAPTOP COMPUTER October 22, 2001 Submitted to:Mr. Eric Dukatz Senior RF Engineer Atheros Communications 529 Almanor Avenue Sunnyvale, CA 94085-3512 Submitted by:Om P. Gandhi Professor of Electrical and Computer Engineering University of Utah 50 S Central Campus Dr., Rm. 3280 Salt Lake City, UT 84112-9206 SAR COMPLIANCE TESTING OF ATHEROS COMMUNICATIONS MODEL AR5BCB-00013 CARDBUS CARD INSERTED INTO A LAPTOP COMPUTER I. Introduction The U.S. Federal Communications Commission (FCC) has adopted limits of human exposure to RF emissions from mobile and portable devices that are regulated by the FCC [1]. The FCC has also issued Supplement C (Edition 97-01) to OET Bulletin 65 [2] and a more recent version of the same [3] defining both the measurement and the computational procedures that should be followed for evaluating compliance of mobile and portable devices with FCC limits for human exposure to radiofrequency emissions. We have used the measurement procedure for SAR compliance testing of the Atheros Communications CardBus card (FCC ID: PPD-AR5BCB-00013) inserted into a laptop computer. A photograph of the unit with the CardBus card inserted into the laptop computer is given in Fig. 1. A picture of the Model AR5BCB-00013 CardBus card placed on the laptop is given in Fig. 2. The Atheros Model AR5BCB-00013 CardBus card operates with a transmit power to up to 21 dBm (126 mW). Since the wireless PC may possibly be placed on a user's lap where the RF antennas would be the closest to the body, a planar phantom model was used for SAR measurements. II. Experimental Measurements of SAR Distribution The testing of the SAR distribution for the Atheros Communications Model AR5BCB-00013 CardBus Card inserted into a laptop computer was done with a planar rectangular box phantom shown in Fig. 3. This box phantom of external dimensions 30 × 50 cm is filled with a tissue-simulant fluid up to a depth of 15.5 cm. To maintain flatness of the phantom, the rectangular box is made of acrylic (ε r = 2.56) of thickness 6.35 mm. The tissue-simulant fluid uses a composition developed at the University of Utah which 2 consists of 68.0% water, 31.0% sugar and 1% HEC. For this composition, we have measured the dielectric properties using a Hewlett Packard (HP) Model 85070B Dielectric Probe in conjunction with HP Model 8720C Network Analyzer (50 MHz-20 GHz). The measured dielectric properties at the mid band frequency of 5.30 GHz are as follows: ε r = 48.5 ± 1.7 and σ = 5.40 ± 0.08 S/m. From the FCC Supplement C [3], we obtain the desired dielectric properties to simulate the body tissue at 5.30 GHz to be ε r = 48.9 and σ = 5.42 S/m. Thus, the measured properties for the body-simulant fluid are close to the desired values. III. Calibration of the E-Field Probe As in some previously reported SAR measurements at 6 GHz [4], we have calibrated the Narda Model 8021 Miniature Broadband Electric Field Probe of tip diameter 4 mm (0.4 to 10 GHz) using a rectangular waveguide WR 159 that was filled with this body-simulant fluid at 5.30 GHz. By comparing the electric fields expected in the tissue from the analytical expressions of the waveguide theory, we obtain a calibration factor of 2.98 (mW/kg)/μV. This is considerably larger than calibration factors of 0.39 and 0.565 (mW/kg)/μV previously reported for the same probe at 835 MHz and 1900 MHz, respectively [5]. This is to be expected since the sensitivity of the diodes used for the Narda Model 8021 Miniature Broadband Electric Field Probe of tip diameter 4 mm is likely to diminish with frequency. I V . The Measured SAR Distributions The SAR distribution was determined using the automated SAR measurement system developed at the University of Utah [4]. As described in [4], this SAR measurement system has been validated using a number of wireless telephones at 835 and 1900 MHz, respectively. 3 The highest SAR region for each of the frequencies (5.26 and 5.32 GHz) was identified in the first instance by using a coarser sampling with a step size of 8.0 mm over three overlapping areas for a total scan area of 8.0 × 9.6 cm. After identifying the region of the highest SAR, the SAR distribution was measured with a resolution of 2 mm in order to obtain the peak 1 cm 3 or 1-g SAR. As given in [5], the SAR measurements are performed at 4, 6, 8, 10, 12 mm height from the bottom surface of the body-simulant fluid. The SARs thus measured were extrapolated to obtain values at 1, 3, 5, 7 and 9 mm height and used to obtain 1-g SARs. The estimated error in determination of peak 1-g SAR is within ± 20% as compared to the values obtained using numerical procedures [5]. The SAR distributions were measured for transmit frequencies of 5.26 and 5.32 GHz and are given in Tables 1 and 2. The peak 1-g SARs at 5.26 and 5.32 GHz are 0.402 and 0.331 W/kg, respectively. For the measurements in Tables 1 and 2, the separation between the Atheros Model AR5BCB-00013 CardBus card and the bottom of the experimental phantom is on the order of 1 cm and yet the peak 1-g SAR is only 0.331- 0.402 W/kg. The end-on SAR value (for a bystander), where the spacing is larger and may be on the order of 2.5 cm or more, is likely to be smaller and was, therefore, not measured. V. Comparison of the Data With FCC 96-326 Guidelines According to the FCC 96-326 Guidelines [1], the peak SAR for any 1-g of tissue should not exceed 1.6 W/kg. For the maximum radiated power condition of 21 dBm (126 mW), the Atheros Communications Model AR5BCB-00013 CardBus card has been measured to give peak 1-g SARs of 0.331-0.402 W/kg which are considerably smaller than 1.6 W/kg. 4 REFERENCES 1 .Federal Communications Commission, "Guidelines for Evaluating the Environmental Effects of Radiofrequency Radiation," FCC 96-326, August 1, 1996. 2 .K.

January 11, 2002 RESPONSES TO FCC QUESTIONS ON THE SAR COMPLIANCE TEST REPORT OF ATHEROS MODEL AR5BCB-00013 DATED NOVEMBER 20, 2001 1.Please use Suppl. C ed 01-01 for all future filings. Due to differing tabulated frequencies, it is unknown whether or not liquid parameters in EA728513 comply with Suppl.. C 01-01. Response: FCC Suppl. C ed 01-01 has indeed been used in preparing this SAR report as far as possible. Though not specifically written at the end of Section II, the desired dielectric properties ε r = 48.9 and σ = 5.42 S/m for "body" tissue at 5.3 GHz were obtained by interpolating the dielectric properties at 3.0 and 5.8 GHz given in Appendix C of FCC Suppl. C ed 01-01. This is a valid procedure since Ref. 12 of FCC Suppl. C ed 01-01 does not give properties for the so-called "body" tissue and Ref. 11 gives properties for the head model only up to 3.0 GHz. 2 .Measurement uncertainty budget is needed. Response: We intend to submit a detailed analysis of the measurement uncertainty budget in future filings. Our present estimate of the measurement accuracy of ±20% is based on the peak 1-g SARs measured as well as calculated for dipole antennas placed against planar phantoms and a number of actual telephones placed against the phantom model of the head [see Ref. 5 of the SAR report -- Q. Yu, et al., IEEE Trans. EMC, Vol. 41(3), pp. 234- 245, August 1999]. Also, a measured peak 1-g SAR of 0.134 W/kg as against an FDTD- calculated SAR of 0.129 W/kg was previously reported for the SAR report of EA101903 which is a very similar device at 5.25 GHz radiating only 16 dBm conducted power. This difference of less than 4% is certainly within the ±20% uncertainty in measured SARs reported for the present SAR compliance test report. 3 .Only 1, 3, 5, 7, 9 mm layer values are shown. Are these interpolated from 4, 6, 8, 10, 12 measured values? Were 4, 6, 8, 10, 12 measured values used in averaging? Response: The SAR values are extrapolated from the values measured at depths of 4, 6, 8, 10 and 12 mm by using a polynomial fit to the data for various locations. To determine peak 1-cm 3 SAR, the extrapolated data thus obtained for depths of 1, 3, 5, 7 and 9 mm is used. 4 .What is loss tangent of 6.35 mm-thick flat phantom at 5.3 GHz? Response: The dielectric constant of the acrylic polystyrene is ε r = 2.56 and its loss tangent given in ITT Handbook [a] is 0.00033 at 3 GHz and 0.0012 at 25 GHz. Thus, the loss tangent is considerably lower than 0.05 suggested as the upper limit in FCC Suppl. C ed 01-01. 2 5 .To verify liquid depth and proper test system operation, we have been requesting graphs of SAR vs. depth into liquid at the peak SAR configuration(s). In future filings, please provide such graphs. Response: The measured variations of SAR vs. depth into the liquid at the peak SAR locations from Tables 1 and 2 of the SAR report are plotted in Fig. a while those from Tables 3 and 4 of the SAR report are plotted in Fig. b. Both Figs. a and b are attached here. 6 .Figures 1, 2 appear to be identical to Figs. 1, 2 in the SAR report of EA101903. Are these identical devices? Response: Figures 1 and 2 are indeed similar to Figs. 1 and 2 in the SAR report of EA101903 since the devices are similar in external appearance and a similar PC is used.

RF Exposure Information - Addendum Re: FCC ID PPD-AR5BCB-00013 Applicant: Atheros Communications, Inc. The application for the above device included a SAR report. This SAR report details results for a phantom-to-EUT separation of 1cm. While the profile of most laptops will ensure this separation distance, under certain circumstances it may be possible that the end user could come closer than 1cm to the device. For this reason, the following warning statement will be placed in a prominent location in the User’s Manual: Warning To comply with the FCC’s rf exposure requirements you must maintain a distance of at least 1cm from the antenna of this device while it is in use.
