Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 SCOPE An electromagnetic emissions test has been performed on the Atheros Communications model AR5BCB-00012 pursuant to Subpart E of Part 15 of FCC Rules for Unlicensed National Information Infrastructure (UNII) devices and RSS-210 Issue 4 for licence-exempt local area network (LELAN) devices. Conducted and radiated emissions data has been collected, reduced, and analyzed within this report in accordance with measurement guidelines set forth in ANSI C63.4-1992 as outlined in Elliott Laboratories test procedures. The intentional radiator above has been tested in a simulated typical installation to demonstrate compliance with the relevant FCC performance and procedural standards. Final system data was gathered in a mode that tended to maximize emissions by varying orientation of EUT, orientation of power and I/O cabling, antenna search height, and antenna polarization. Every practical effort was made to perform an impartial test using appropriate test equipment of known calibration. All pertinent factors have been applied to reach the determination of compliance. The test results recorded herein are based on a single type test of the Atheros Communications model AR5BCB-00012 and therefore apply only to the tested sample. The sample was selected and prepared by Eric Dukatz of Atheros Communications. OBJECTIVE The primary objective of the manufacturer is compliance with Subpart E of Part 15 of FCC Rules for the radiated and conducted emissions of intentional radiators. Certification of these devices is required as a prerequisite to marketing as defined in Part 2 the FCC Rules. Certification is a procedure where the manufacturer or a contracted laboratory makes measurements and submits the test data and technical information to the FCC. The FCC issues a grant of equipment authorization upon successful completion of their review of the submitted documents. Once the equipment authorization has been obtained, the label indicating compliance must be attached to all identical units which are subsequently manufactured. File: R44340 Page 5 of 19 pages

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 EQUIPMENT UNDER TEST (EUT) DETAILS GENERAL The Atheros Communications model AR5BCB-00012 is a PC Card bus standard UNII Radio which is designed to operate from 5.18 GHz to 5.32 GHz. The system is intended for indoor use only. Normally, the EUT would be placed in a laptop PC during normal use. The EUT was, therefore, placed in a laptop PC and treated as table-top equipment during testing to simulate the end user environment. The sample was received on July 23, 2001 and tested on July 23, July 24, August 6, August 7 and August 8, 2001. The EUT consisted of the following component(s): Manufacturer/Model/Description Serial Number Atheros AR5BCB-00012 CardBus UNII Radio ECC26 ENCLOSURE The EUT enclosure is primarily constructed of fabricated sheet steel. It measures approximately 7 cm wide by .5 cm deep by 10 cm high. MODIFICATIONS The EUT did not require modifications during testing in order to comply with the emission specifications. SUPPORT EQUIPMENT The following equipment was used as local support equipment for emissions testing: Manufacturer/Model/Description Serial Number FCC ID Number Dell PP01L Laptop PC TW-0791 UH-12800-OB4-3546 Hewlett Packard 2225C ThinkJet 2636S40326 DS16XU2225C Parallel Printer – ac USRobotics Pilot 5000 Palm 604719G68390 MQ90001 Computing Platform The following equipment was used as remote support equipment for emissions testing: Manufacturer/Model/Description Serial Number FCC ID Number None - - File: R44340 Page 8 of 19 pages

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 EUT INTERFACE PORTS The I/O cabling configuration during emissions testing below 1GHz was as follows: Cable(s) Port Connected To Description Shielded or Unshielded Length (M) Laptop Serial Palm Pilot Serial Shielded 2 Laptop Parallel Printer Parallel Shielded 3 The host laptop was not connected to peripherals during spurious emissions testing above 1GHz. EUT OPERATION The radio was transmitting at full power on the specified channel with a duty cycle of 99% (maximum allowed). The EUT was tested in both normal mode (channel bandwidth of approximately 30 MHz) and turbo mode (channel bandwidth of approximately 60 MHz). "Turbo Mode" allows data rates of up to 72Mb/s. At data rates higher than 12Mb/s the PA gain is reduced to improve signal fidelity. The device was, therefore, tested in turbo mode at the data rate that produced the highest output power for turbo mode (12Mb/s). ANTENNA REQUIREMENTS As the device is intended to operate in the 15.15 – 15.25 GHz band an integral antenna as detailed in 15.407 (d) and RSS-210 6.2.2(q1) (i) is required. The antenna for the device is an integral antenna with a gain of 1.45 dBi. File: R44340 Page 9 of 19 pages

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 TEST SITE GENERAL INFORMATION Final test measurements were taken on July 23, July 24, August 6, August 7 and August 8, 2001 at the Elliott Laboratories Open Area Test Sites #1 and #4 located at 684 West Maude Avenue, Sunnyvale, California. The test site contains separate areas for radiated and conducted emissions testing. Pursuant to section 2.948 of the Rules, construction, calibration, and equipment data has been filed with the Federal Communications Commission. In accordance with Industry Canada rules detailed in RSS 210 Issue 4 and RSS-212, construction, calibration, and equipment data for the test sites have been filed with the Federal Communications Commission. The FCC recommends that ambient noise at the test site be at least 6 dB below the allowable limits. Ambient levels are below this requirement with the exception of predictable local TV, radio, and mobile communications traffic. The test site contains separate areas for radiated and conducted emissions testing. Considerable engineering effort has been expended to ensure that the facilities conform to all pertinent FCC requirements. CONDUCTED EMISSIONS CONSIDERATIONS Conducted emissions testing is performed in conformance with ANSI C63.4-1992. Measurements are made with the EUT connected to the public power network through a nominal, standardized RF impedance, which is provided by a line impedance stabilization network, known as a LISN. A LISN is inserted in series with each current-carrying conductor in the EUT power cord. RADIATED EMISSIONS CONSIDERATIONS The FCC has determined that radiation measurements made in a shielded enclosure are not suitable for determining levels of radiated emissions. Radiated measurements are performed in an open field environment. The test site is maintained free of conductive objects within the CISPR defined elliptical area incorporated in ANSI C63.4 guidelines. File: R44340 Page 10 of 19 pages

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 MEASUREMENT INSTRUMENTATION RECEIVER SYSTEM An EMI receiver as specified in CISPR 16-1 is used for emissions measurements. The receivers used can measure over the frequency range of 9 kHz up to 2000 MHz. These receivers allow both ease of measurement and high accuracy to be achieved. The receivers have Peak, Average, and CISPR (Quasi-peak) detectors built into their design so no external adapters are necessary. The receiver automatically sets the required bandwidth for the CISPR detector used during measurements. For measurements above the frequency range of the receivers, a spectrum analyzer is utilized because it provides visibility of the entire spectrum along with the precision and versatility required to support engineering analysis. Average measurements above 1000MHz are performed on the spectrum analyzer using the linear-average method with a resolution bandwidth of 1 MHz and a video bandwidth of 10 Hz. INSTRUMENT CONTROL COMPUTER The receivers utilize either a Rohde and Schwarz EZM Spectrum Monitor/Controller or contain an internal Spectrum Monitor/Controller to view and convert the receiver measurements to the field strength at an antenna or voltage developed at the LISN measurement port, which is then compared directly with the appropriate specification limit. This provides faster, more accurate readings by performing the conversions described under Sample Calculations within the Test Procedures section of this report. Results are printed in a graphic and/or tabular format, as appropriate. A personal computer is used to record all measurements made with the receivers. The Spectrum Monitor provides a visual display of the signal being measured. In addition, the controller or a personal computer run automated data collection programs which control the receivers. This provides added accuracy since all site correction factors, such as cable loss and antenna factors are added automatically. LINE IMPEDANCE STABILIZATION NETWORK (LISN) Line conducted measurements utilize a fifty microhenry Line Impedance Stabilization Network as the monitoring point. The LISN used also contains a 250 uH CISPR adapter. This network provides for calibrated radio frequency noise measurements by the design of the internal low pass and high pass filters on the EUT and measurement ports, respectively.

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 POWER METER Either a spectrum analyzer or a power meter and thermister mount are used for all direct output power measurements from transmitters. FILTERS/ATTENUATORS External filters and precision attenuators are often connected between the receiving antenna or LISN and the receiver. This eliminates saturation effects and non-linear operation due to high amplitude transient events. ANTENNAS A biconical antenna is used to cover the range from 30 MHz to 300 MHz and a log periodic antenna is utilized from 300 MHz to 1000 MHz. Narrowband tuned dipole antennas are used over the entire 30 to 1000 MHz range for precision measurements of field strength. Above 1000 MHz, a horn antenna is used. The antenna calibration factors are included in site factors programmed into the test receivers. ANTENNA MAST AND EQUIPMENT TURNTABLE The antennas used to measure the radiated electric field strength are mounted on a non- conductive antenna mast equipped with a motor-drive to vary the antenna height. ANSI C63.4 specifies that the test height above ground for table mounted devices shall be 80 centimeters. Floor mounted equipment shall be placed on the ground plane if the device is normally used on a conductive floor or separated from the ground plane by insulating material from 3 to 12 mm if the device is normally used on a non-conductive floor. During radiated measurements, the EUT is positioned on a motorized turntable in conformance with this requirement. INSTRUMENT CALIBRATION All test equipment is regularly checked to ensure that performance is maintained in accordance with the manufacturer's specifications. All antennas are calibrated at regular intervals with respect to tuned half-wave dipoles. An exhibit of this report contains the list of test equipment used and calibration information.

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 TEST PROCEDURES EUT AND CABLE PLACEMENT The FCC requires that interconnecting cables be connected to the available ports of the unit and that the placement of the unit and the attached cables simulate the worst case orientation that can be expected from a typical installation, so far as practicable. To this end, the position of the unit and associated cabling is varied within the guidelines of ANSI C63.4, and the worst case orientation is used for final measurements. CONDUCTED EMISSIONS Conducted emissions are measured at the plug end of the power cord supplied with the EUT. Excess power cord length is wrapped in a bundle between 30 and 40 centimeters in length near the center of the cord. Preliminary measurements are made to determine the highest amplitude emission relative to the specification limit for all the modes of operation. Placement of system components and varying of cable positions are performed in each mode. A final peak mode scan is then performed in the position and mode for which the highest emission was noted on all current carrying conductors of the power cord. RADIATED EMISSIONS Radiated emissions measurements are performed in two phases as well. A preliminary scan of emissions is conducted in which all significant EUT frequencies are identified with the system in a nominal configuration. At least two scans are performed from 30 MHz up to the frequency required by the regulation specified on page 1. One or more of these is with the antenna polarized vertically while the one or more of these is with the antenna polarized horizontally. During the preliminary scans, the EUT is rotated through 360°, the antenna height is varied and cable positions are varied to determine the highest emission relative to the limit. A speaker is provided in the receiver to aid in discriminating between EUT and ambient emissions. Other methods used during the preliminary scan for EUT emissions involve scanning with near field magnetic loops, monitoring I/O cables with RF current clamps, and cycling power to the EUT. Final maximization is a phase in which the highest amplitude emissions identified in the spectral search are viewed while the EUT azimuth angle is varied from 0 to 360 degrees relative to the receiving antenna. The azimuth which results in the highest emission is then maintained while varying the antenna height from one to four meters. The result is the identification of the highest amplitude for each of the highest peaks. Each recorded level is corrected in the receiver using appropriate factors for cables, connectors, antennas, and preamplifier gain. Emissions which have values close to the specification limit may also be measured with a tuned dipole antenna to determine compliance. File: R44340 Page 13 of 19 pages

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 CONDUCTED EMISSIONS FROM ANTENNA PORT Direct measurements are performed with the antenna port of the EUT connected to either the power meter or spectrum analyzer via a suitable attenuator and/or filter. These are used to ensure that the front end of the measurement instrument is not overloaded by the fundamental transmission. Measurement bandwidths (video and resolution) are set in accordance with FCC procedures for the type of radio being tested. File: R44340 Page 14 of 19 pages

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 SPECIFICATION LIMITS AND SAMPLE CALCULATIONS The limits for conducted emissions from the AC power port are given in units of microvolts, the limits for radiated electric field emissions are given in units of microvolts per meter at a specified test distance and the output power limits are given in temrs of Watts, milliwatts or dBm. Data is measured in the logarithmic form of decibels relative to one microvolt, or dB microvolts (dBuV). For radiated emissions, the measured data is converted to the field strength at the antenna in dB microvolts per meter (dBuV/m). The results are then converted to the linear forms of uV and uV/m for comparison to published specifications. Where the radiated electric field strength is expressed in terms of the equivalent isotropic radiated power (eirp) the following formula is used to determine the field strength limit in terms of microvolts per meter at a distance of 3m from the equipment under test: E = 1000000 v 30 P microvolts per meter 3 where P is the eirp (Watts) For reference, converting the voltage and electric field strength specification limits from linear to decibel form is accomplished by taking the base ten logarithm, then multiplying by 20. Conversion of power specification limits from linear units (in milliwatts) to decibel form (in dBm) is accomplished by taking the base ten logarithm, then multiplying by 10.

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 SAMPLE CALCULATIONS - CONDUCTED EMISSIONS Receiver readings are compared directly to the conducted emissions specification limit (decibel form) as follows: Rr - B = C and C-S=M where: Rr = Receiver Reading in dBuV B = Broadband Correction Factor* C = Corrected Reading in dBuV S = Specification Limit in dBuV M = Margin to Specification in +/- dB * Broadband Level - Per ANSI C63.4, 13 dB may be subtracted from the quasi-peak level if it is determined that the emission is broadband in nature. If the signal level in the average mode is six dB or more below the signal level in the peak mode, the emission is classified as broadband. File: R44340 Page 18 of 19 pages

Elliott Laboratories, Inc. -- EMC Department Test Report Report Date: August 16, 2001 SAMPLE CALCULATIONS - RADIATED EMISSIONS Receiver readings are compared directly to the specification limit (decibel form). The receiver internally corrects for cable loss, preamplifier gain, and antenna factor. The calculations are in the reverse direction of the actual signal flow, thus cable loss is added and the amplifier gain is subtracted. The Antenna Factor converts the voltage at the antenna coaxial connector to the field strength at the antenna elements. A distance factor, when used for electric field measurements, is calculated by using the following formula: Fd = 20*LOG10 (Dm/Ds) where: Fd = Distance Factor in dB Dm = Measurement Distance in meters Ds = Specification Distance in meters Measurement Distance is the distance at which the measurements were taken and Specification Distance is the distance at which the specification limits are based. The antenna factor converts the voltage at the antenna coaxial connector to the field strength at the antenna elements. The margin of a given emission peak relative to the limit is calculated as follows: Rc = Rr + Fd and M = Rc - Ls where: Rr = Receiver Reading in dBuV/m Fd = Distance Factor in dB Rc = Corrected Reading in dBuV/m Ls = Specification Limit in dBuV/m M = Margin in dB Relative to Spec File: R44340 Page 19 of 19 pages
