Justification The EUT was connected to the host PC and tested as a customer would normally use it. The modulation and data rates were changed in order to find the worst case emissions. It was found that the 100%

Tx, TFC 4, 53.3 Mbps data rate, and payload set to random, provided the worst case emissions. The lid of host PC was at 45 degree angle position. All testing was done in this configuration. The EUT was configured to run preliminary scans in a mode where the symbols can be sent in a random sequence. The random sequence smoothes out the spectrum and makes the signal more white noise like. This mode represents the worst-case real world usage scenario based on the FCC waiver (Adopted March 10, 2005) that allows radios under test to be operated as they are intended to be used in the field. The data presented in section 6 is the worst-case data. To insure maximum emissions were detected, the system was rotated 360 , the antenna height was varied from 1 to 4 meters in 1 meter steps above the ground plane and positioned in both horizontal and vertical polarizations. The maximum emissions are represented in the collected data enclosed. Above 960 MHz, the measurements were made at equal or less than 3 meters due to the extremely low emission limits outside the UWB bandwidth margins. At 3 meters, the instrument noise floor is at or above the limits specified in 15.519(c). The intentional emissions were measured at 3m distance. The highest frequency employed in 47 CFR Section 15.33 to determine the frequency range over which radiated emissions are made were based on the center frequency, f frequency was generated within the UWB device. For measuring c, unless a higher Page 6 of 48 emission levels, the spectrum was investigated from the lowest frequency generated in the UWB, without going below 9 kHz, up to the frequency range shown in Section 15.33(a) of 47 CFR or up to f c +

3/(pulse width in seconds), whichever was higher. There is no requirement to measure emissions beyond 40 GHz provided f less than 10 GHz; beyond 100 GHz if f below 30 GHz; or beyond 200 GHz if f c was at or above 30 GHz. c was c was at or above 10 GHz and The center frequency (of the highest sub band) f 4487.25MHz. Therefore; the highest frequency to be measured was 40 GHz. c was found to be 2.5.4. Mode(s) of Operation The device complies with 15.519(a)(1) 2.6. Modifications Required for Compliance No modifications were required to bring the unit into compliance with the appropriate sections of FCC 47 CFR Part 15. Page 7 of 48 3.

Radiated Emissions Frequency Range 1 m 3 m 10 m 30 MHz to 200 MHz N/A 200 MHz to 1 GHz 1 GHz to 18 GHz 18 GHz to 40 GHz N/A 4.5 dB 4.2 dB 3.8 dB 3.8 dB 4.6 dB N/A 3.5 dB 3.5 dB N/A N/A Conducted Emissions Frequency Range 150 kHz to 30 MHz 2.6 dB Note: The combined level of uncertainty in each case above was expanded to provide a confidence level of approximately 95% (k=2). 4.4. Test Setup for UWB Device Tests 4.4.1. EUT Setup The EUT was connected to the host PC. AC power adapters were connected with 120VAC-60Hz power source and to the host PC. A continuous transmission of random data was sent at 53.3 Mbps. SETUP diagram ThinkPad AC Power Supply PC PCIe EUT Page 10 of 48 4.4.2. Radiated Emission Test Setup In order to test compliance of EUT, facilities described section 3, and test and measurement equipment listed in section 4.1, were used. For all measurements the EUT was located on center of a table whose top was 80 cm above the ground plane. The table was constructed of non-

conductive materials and the dimensions were 0.8 meter by 1.2 meter. The table was located in the center of the turntable. For the test four types of receive antennas were used depending on frequency range. The antenna was held on an antenna mast which has the ability to switch the polarization of the receive antenna by 90 degree by means of mechanical rotation. The distance between the EUT and the receive antenna was equal or less than 3 meters, depending on the test. Shorter measurement distances may be used to improve the measurement systems noise floor. As Subpart F description is based on the measurement in distance of 3 meters, the data obtained at 1meter distance was compared to the calculated limit for 1m distance:

Limit at 1meter distance (dBm)

= limit at 3 meter distance (dBm) -20log(1/3)(dB)

= limit at 3 m distance (dBm) - 9.54(dB). The maximization of the radiated signal was achieved by rotating the EUT over 360 degrees in the azimuth, because the EUT is designed for table top usage so that orienting the EUT in three orthogonal axes was difficult. Additionally, the receive antenna was scanned in height from 1 meter to 4 meters (while maintaining boresight alignment) with both horizontal and vertical polarizations being recorded. The maximization was performed by use of automated software with CPU controlled maximum-hold function for both single and multiple sweeps. The spectrum analyzer and EMI receiver was set up as described in each test procedure in section 6. The data used to determine compliance of EUT was calculated from the data following the method described in section 4.6. The equipment set up for the radiated emissions tests followed the guidelines in ANSI C63.4: latest edition. 4.4.3.Conducted Emission Test Setup Not applicable to this device. Page 11 of 48 4.4.4.

EUT Setup for Digital Circuitry Radiated Emission Tests In order to test compliance of EUT, facilities described section 3, and test and measurement equipment listed section 4.1, were used. all measurement, the EUT was located on a table whose top was 0.8 m above the ground plane. The table was constructed of non-

conductive materials and the dimensions were 0.8 meter by 1.2 meter. The table was located in the center of the turntable. To test for digital circuit radiation from the EUT, the antenna of EUT was disconnected and a 50-ohm terminator was connected. For 4.5. Measurement Calculations 4.5.1. Field Strength Calculations The field strength is calculated by taking the received spectrum analyzer (or receiver) signal and adjusting it by the system parameters. These system parameters are the antenna factor (AF);

any cable, coupler, filter or switching losses (CL); and the preamplifier gain (PG). The basic formula is displayed below. E (dBm V/m) = SA (dBm V) + AF (dB/m) + CL (dB) PG (dB) Where:

E is the electric field represented in dB m V/m SA is the spectrum analyser (or receiver) reading in dB m V AF is the receive antennas factor in dB/m CL is the cable, etc. system losses in dB PG is the external pre-amplifier gain in dB Assume a spectrum analyzer reading of 50 dB m V at 80 MHz on a 3 m site. With an antenna factor of 10 dB/m, system losses of about 1.5 dB, and a pre-amplifier gain of 25 dB, the resulting electric field strength would be calculated as follows. E (dBm V/m) = 50 (dBm V) + 10 (dB/m) + 1.5 (dB) 25 (dB) = 36.5 dBm V/m 4.5.2. EIRP Calculations As defined in FCC 47 CFR Part 15, Subpart F (15.503 k), EIRP is the equivalent isotropic radiated power, i.e. the product of the power supplied to the antenna and the antenna gain in a given direction relative to an isotropic antenna. The EIRP, in terms of dBm, can be converted to field strength, in dB m V/m at 3 meters, by adding 95.2 m V/m at 3 meters can be dB. Conversely, the field strength in dB converted to the EIRP in dBm by subtracting 95.2 dB. As used in Subpart F, EIRP refers to the highest signal strength measured in any Page 14 of 48 direction and at any frequency from the UWB device, as tested in accordance with the procedures specified in 15.31(a) and 15.523 of FCC 47 CFR. As in the example above, assume a spectrum analyzer reading of 50 dBm V at 80 MHz on a 3 m site. With an antenna factor of 10 dB/m, system losses of about 1.5 dB, and a pre-amplifier gain of 25 dB, the resulting electric field strength would be calculated as follows. E (dBm V/m) = 50 (dBm V) + 10 (dB/m) + 1.5 (dB) 25 (dB) = 36.5 dBm V/m Now to convert to an EIRP reading at 3 meters use EIRP (dBm) = E

(dBm V/m) 95.2 (dB) EIRP (dBm) = 36.5 (dBm V/m) 95.2 (dB) = -58.7 dBm 4.5.3. UWB Maximum Permissible Exposure Transmitter Category: Mobile Device. A mobile device is defined as a transmitting device designed to be used in other than fixed locations and be generally used in such as way that a separation distance of at least 20 cm is normally maintained between the transmitters radiating structures and the body of the user or nearby persons. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR 2.1091. Device Usage: General Population/Uncontrolled Exposure. The general population/uncontrolled exposure limits are applicable to situation in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Exposure Calculation: According to 1.1310 of the FCC rules, the power density limit for the General Population/Uncontrolled Exposure is 1 mW/cm 2. According to the mobile product device category, this value is to be calculated at a distance of 20 cm. The following formula is used to calculate the power density.

=

EIRP r 4 2 p Where:

S = Power Density P = Power at the Antenna Terminal G = Gain of the Transmit Antenna Page 15 of 48 EIRP = Effective Isotropic Radiated Power r = Measurement Distance From the measurement data we can see that the peak detected EIRP at 3 meters distance and 8 MHz RBW yields a result of 23.17 dBm. Translated to 20 cm this would yield a result of 0.352 dBm. Correlating this to a worst-case scenario with a 50 MHz RBW would yield 17.9 dBm EIRP. 17.9 dBm is equal to 61.7 mW EIRP. Plugging this into the above equation yields:

Operational Limitations FCC 47 CFR Section 15.519 (a)(1) A UWB device operating under the provisions of this section shall transmit only when it is sending information to an associated receiver. The UWB intentional radiator shall cease transmission within 10 seconds unless it receives an acknowledgement from the associated receiver that its transmission is being received. An acknowledgment of reception must continue to be received by the UWB intentional radiator at least every 10 seconds or the UWB device must cease transmitting. Description in user manual FCC 47 CFR Section 15.519 (a)(2) The use of antennas mounted on outdoor structures, e.g., antennas mounted on the outside of a building or on a telephone pole, or any fixed outdoors infrastructure is prohibited. Antennas may be mounted only on the hand held UWB device. The client has been informed of this requirement FCC 47 CFR Section 15.519 (a)(3) UWB devices operating under the provisions of this section may operate indoors or outdoors. The client has been informed of this requirement Page 17 of 48 6. Test Limits, Procedures, Results and Setups 6.1. UWB Bandwidth 6.1.1. Test Limits Ultra-wideband (UWB) transmitter. An intentional radiator that, at any point in time, has a fractional bandwidth equal to or greater than 0.20 or has a UWB bandwidth equal to or greater than 500 MHz, regardless of the fractional bandwidth The UWB bandwidth is the frequency band bounded by the points that are 10 dB below the highest radiated emission, as based on the complete transmission system including the antenna. The upper boundary is designated f H and the lower boundary is designated f The frequency at which the highest radiated emission occurs is designated fM. Center frequency. The center frequency, f C, equals (fH + fL)/2. Fractional bandwidth. The fractional bandwidth equals 2(f H - f L)/ (f H +

fL). As per section 15.519(b), the UWB bandwidth of a UWB system operating under the provisions of this section must be contained between 3100 MHz and 10600 MHz L. 6.1.2.Test Procedure Facilities and equipment was set up as described in section 4;

resolution bandwidth (RBW) of 8 MHz, video bandwidth (VBW) of 8 MHz, peak detector, and the sweep time was set to auto. The EUT was located at 3 meter distance from the receive antenna. Maximum emission amplitude was determined from the measured data for both horizontal and vertical polarization and the higher amplitude of emission of these two polarizations was used to determine the frequency at which the highest radiated emission occurs, fM. Next, the points that are 10dB or more below the highest radiated emission were observed in a search from f M in both the lower and higher frequency direction in the measured frequency EIRP graph, they are denoted as f L and fH, respectively. The UWB bandwidth is the difference between fL and fH. At the request of the FCC the individual UWB bandwidths were measured for each sub-band of the UWB spectrum. Both horizontal and vertical polarizations were taken into account to determine the full UWB BW on the maximized (in azimuth and elevation) signals. Page 18 of 48 6.1.3.

Instead, the emissions from that digital circuitry are subject to the same limits as those applicable to the transmitter. If it can be clearly demonstrated that an emission from a UWB transmitter is due solely to emissions from digital circuitry contained within the transmitter and that the emission is not intended Page 22 of 48 to be radiated from the transmitters antenna, the limits shown in Section 15.209 shall apply to that emission rather than the limits specified in this section. 6.2.2. Test Procedure The measurements made over the frequency range from 30 MHz to 960 MHz were maximized using an EMI receiver with peak detector capabilities. Measurements of the radiated field from 30 MHz to 960 MHz were made with the measurement antenna located a distance of 3 meters from the EUT and the final measurements utilizing a quasi-

peak detector at the frequencies with the largest amplitudes. The relative CISPR resolutions bandwidth of 120 kHz was used for these measurements. In the case where there was sufficient margin between the peak detected maximized spectrum and the quasi-peak limit lines, no additional measurements were undertaken. Measurements above 960 MHz were maximized using a spectrum analyzer with RMS detector capabilities. A spectrum analyzer was used for the final measurements utilizing an RMS detector at the frequencies with the largest amplitudes. The prescribed RBW of 1 MHz and VBW of 3 MHz, and a 1 msec averaging time were used for these measurements. Measurements of the radiated field at frequencies above 960 MHz were made with the measurement antenna located a distance of 1 meter from the EUT. The equipment set up for the radiated emissions tests followed the guidelines in ANSI C63.4. 6.2.3.Test Results The spectrum between 30 MHz and 960 MHz contained no intentional radiation and lies below the limits. The spectrum between 960 MHz and 12 GHz contained intentional UWB signals between 3100 MHz and 10600 MHz and lie below the limits. No other intentional emissions above 10600 MHz were detected. The maximum frequency tested was 40 GHz. Per 47 CFR, Part 15, Subpart F, 15.521(c) (15.209) all digital emissions from the transmitter whether radiating from the antenna port or not intended to be radiated from the antenna port meet the 15.209 subpart C limits. Additional measurements in the 960 MHz to 40 GHz range were performed to determine the nature of all unintentional emissions in this span. Conducted antenna port measurement and terminated antenna port measurement were done in the 960 MHz to 8 GHz range to show that all noise peaks have the same frequency and polarization Page 23 of 48 and are determined to be emission from the digital circuit and are not intended to be radiated from the antenna. Per 47 CFR, Part 15, Subpart F, 15.505(a) (15.109) all emissions from the digital devices not directly associated with the operation of the transmitter meets the Class B limits of 15.109 Refer to the UWB Radiated Emissions 960 MHz to 40 GHz section for specific data presentation.

Peak Radiated Emissions in a 50 MHz RBW 6.4.1. Test Limits There is a limit on the peak level of the emissions contained within a 50 MHz bandwidth centered on the frequency at which the highest radiated emission occurs, f M. That limit is 0 dBm EIRP. It is acceptable to employ a different resolution bandwidth, and a correspondingly different peak emission limit, following the procedures described in Section 15.521. 6.4.2. Test Procedure The measurements made over the intentionally radiating frequency range of the EUT, from 3100 MHz to 10600 MHz, were maximized using a spectrum analyzer with peak detector capabilities. A spectrum analyzer was used for the final measurement utilizing a peak detector at the frequency with the largest amplitude. The spectrum analyzer did not support the prescribed resolution bandwidth of 50 MHz. However, when a peak measurement is required, it is acceptable to use a resolution bandwidth other than the 50 MHz specified in 47 CFR Part 15, Subpart F. The resolution bandwidth for this measurement was set to 8 MHz. A setting of 8MHz RBW has been determined to have an actual impulse response bandwidth of 6.7 MHz. Therefore the limit line is reduced by 20Log(6.7/50). The measurement was centered on the frequency at which the highest radiated emission occurred, f M. The video bandwidth was 8 MHz. Since a resolution bandwidth other than 50 MHz was employed, the peak EIRP limit has to be adjusted by the resolution bandwidth ratio of 20log(RBW/50)dB, where RBW is the resolution bandwidth used for the measurement expressed in MHz. The equipment set up for the radiated emissions tests followed the guidelines in ANSI C63.4. Page 40 of 48 6.4.3. Test Results UWB Peak Radiated Emissions in 50 MHz RBW Requirements:

HSINCHU SCIENCE PARK BRANCH OFFICE MIN SHENG PLANT 5F-1, 5 Hsin-An Road 4-1 Ming-Sheng St., Hsinchu, Science-Based Industrial Park T u-Cheng Industrial Area, Taiwan, R.O.C. Taiwan, R.O.C TEL:+886-3-5784975 TEL:+886-2-2267 6511 FAX:+886-3-5775100 FAX:+886-2-2267 6512 The ThinkPad Wireless USB Half Mini PCI Express Form Factor Card (HMC) Theory of Operation The ThinkPad Wireless USB Half Mini PCI Express Form Factor Card (HMC) is a cost-effective, highly-

integrated design that provides wireless UWB high-speed services for wired USB devices. The HMC design provides a complete end-to-end solution while leveraging latest breakthrough wireless performance. The ThinkPad Wireless USB HMC is shipped as a complete package including both hardware and software support. The ThinkPad Wireless USB HMC includes a working hardware sample along with users guide, and a quick-start guide. The software package includes a Host Wired Adapter (HWA) driver/firmware and DWA firmware along with the Microsoft Windows-based utility which supports device discovery, multiple association options, field upgrade functionality, and comprehensive diagnostics. The ThinkPad Wireless USB HMC is designed around WiQuests WQST110 and WQST101, the industrys leading high-performance ultrawideband (UWB) chipset. The WQST110 includes a WiMedia-based ultrawideband media access controller (MAC) and physical layer (PHY) baseband processor. The WQST101 is a direct conversion UWB RF transceiver. These two devices and related components fit into a standard Half Mini PCI Express form factor. The ThinkPad Wireless USB HMC is an Ultrawideband (UWB) WiMedia Mode 1-compliant device that operates in the 3168-4752MHz Band group. The ThinkPad Wireless USB HMC transmits WiMedia UWB signal that has instantaneous bandwidth (BW) greater than 500MHz, or fractional occupied BW greater than 20 percent. The 1584MHz wide band represents 40 percent bandwidth (fractional bandwidth equals 2*(Fh-Fl)/(Fh+Fl), where Fh is upper boundary and Fl is lower boundary). Band Group 1 is divided into 3 individual bands, each 528MHz wide, with center frequencies of 3432MHz, 3960MHz and 4488MHz, respectively. The ThinkPad Wireless USB HMC transmits either by hopping between the 3 bands or stationary on each band. FCC Part 15 regulation in Subpart F, Section 15.517 and 15.519 specifies maximum average Equivalent Iso-tropically Radiated Power (EIRP) of 41.3dBm

(53.9dBuV/m) measured using a resolution bandwidth of 1MHz. EIRP in dBm could be converted to a field strength, in dBuV/m at 3 meters, by adding 95.2dB. Since the ThinkPad Wireless USB HMC occupies approximately 1584MHz while hopping (528MHz instantaneously) the average transmitted power is on the order of -9.3dBm (or -14dBm when not hopping). The 528MHz wide signal is composed of 122 modulated Orthogonal Frequency Division Multiplexed (OFDM) sub-

carriers.
