Dear Diane, The users manual has been revised and following language has been added to the manual. Please review it at your earliest convenience. Thanks. Re: FCC ID O9C-SL3040 Applicant: 3Com Corporation Correspondence Reference Number: 25672 731 Confirmation Number: EA362193 Please provide an updated user manual with the host clearly defined that RF exposure evaluation applies too. In this case "substantially similar" laptop use only was evaluation. Product is not authorized for use in PDAs or other portable host devices. <Response> Following warning language has been added to p13 of users manual “This device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz frequency range. The FCC requires this product to be used only indoors to reduce the potential for harmful interference to co-channel Mobile Satellite systems. This device has been tested for compliance with FCC RF Exposure (SAR) limits in the typical laptop computer configuration and this device can be used in "substantially similar" laptop computers with side mounted PCMCIA slots. This device cannot be used with handheld PDAs (personal digital assistants) or other portable host devices. This device and its antenna must not be co-located or operated in conjunction with any other antenna or transmitter.” Best regards, Steve Cheng EMC Engineering Manager Compliance Certification Services 561F Monterey road, Morgan Hill, CA 95037-9001 Tel: (408) 463-0885, Fax: (408) 463-0888 [email protected]

Toshiba Tecra 750 DVD s/n: 38638812-3 2. Hewlett Packard (HP) Pavillion s/n: TW00311692 3. Dell Inspiron 4000 s/n: C7TKD01 I. Introduction We have used the measurement procedures outlined in FCC Supplement C (Edition 97- 01) to OET Bulletin 65 [1] and an updated version of the same [2] for evaluating compliance of the 3Com 802.11 a/b/g Cardbus Card Model SL-3040 with three host computers. Photographs of the 3Com Cardbus Card inserted in the three host computers are given in Figs. 1a, b, c, respectively. The salient features of the 802.11 a/b/g antennas are as follows: 802.11a 5.15 to 5.35, 5.725 to 5.805 GHz (base and turbo modes) 802.11b 2.412 to 2.462 GHz (base mode) 802.11g 2.412 to 2.462 GHz (base and turbo modes) For SAR measurements, two configurations of each of the wireless PCs relative to the planar phantom have been used. These are as follows: a. Configuration 1 is for the wireless PC placed on a user's lap. For this configuration, a planar phantom model with inside dimensions 12" x 16.5" (30.5 x 41.9 cm) and a base thickness of 2.0 ± 0.2 mm (recommended in [2]) was used for SAR measurements and the bottom side of each of the laptop computer was pressed against it (see Fig. 2). b. Configuration 2 -- Edge-on position. This configuration corresponds to a bystander close to the outer edge of the Cardbus Card. For this configuration, the PC is placed at 90° with the edge of the 3Com Model SL-3040 Cardbus Card pressed against the bottom of the planar phantom. A photograph for this edge-on position for SAR testing is given in Fig. 3. Similarly, pressed additional host PCs i.e. HP Pavillion and Dell Inspiron 4000 are also used for SAR measurements. 2 II. The SAR Measurement System The University of Utah SAR Measurement System has been described in peer-reviewed literature [3]. A photograph of the SAR Measurement System is given in Fig. 4. This SAR Measurement System uses a computer-controlled 3-D stepper motor system (Arrick Robotics MD-2A). A triaxial Narda Model 8021 E-field probe is used to determine the internal electric fields. The positioning repeatability of the stepper motor system moving the E-field probe is within ±0.1 mm. Outputs from the three channels of the E-field probe are dc voltages, the sum of which is proportional to the square of the internal electric fields ( ) 2 i E from which the SAR can be obtained from the equation SAR = ( ) 2 i Eσρ, where σ and ρ are the conductivity and mass density of the tissue-simulant materials, respectively [4]. The dc voltages for the…

Gandhi, Life Fellow, IEEE, and Gang Kang, Senior Member, IEEE Department of Electrical and Computer Engineering University of Utah Salt Lake City, Utah 84112, U.S.A. Abstract Compliance with safety guidelines prescribed in terms of maximum electromagnetic power absorption (specific absorption rate or SAR) for any 1- or 10-g of tissue is required for all newly-introduced personal wireless devices such as Wi-Fi PCs. The prescribed SAR measuring system is a planar phantom with a relatively thin base of thickness 2.0 mm filled with a lossy fluid to simulate dielectric properties of the tissues. A well-characterized, broadband irradiator is required for SAR system validation and/or submerged E-field probe calibration for the new 802.11a frequencies in the 5-6 GHz band. We describe an open-ended waveguide system that may be used for this purpose. Using a fourth-order polynomial least-square fit to the experimental data gives SAR variations close to the bottom surface of the phantom that are in excellent agreement with those obtained using the FDTD numerical method. The experimentally-determined peak 1-g SARs are within 1 to 2 percent of those obtained using the FDTD both at 5.25 and 5.8 GHz.

Gandhi, Life Fellow, IEEE, and Gang Kang, Senior Member, IEEE I. Introduction Compliance with the safety guidelines such as those proposed by IEEE [1] ICNIRP [2], etc. is required by regulatory agencies in the United States and elsewhere for all newly- introduced personal wireless devices such as Wi-F…
