2 Chapter 1 About the Wireless Mini PCI Card 1-1 Introduction The Compaq 802.11b Mini PCI card allows you to access wireless Local Area Networks, share a local printer and files with others in your network, access the Internet, and roam about the officewire-free. This wireless Local Area Network solution is designed for both large and small businesses, and it is scalable so that you can add users and new network features as your networking needs grow. 1-2 Using a Wireless Local Area Network This product is a Local Area Network (LAN) device. A LAN is composed of two or more computers that are connected to each other in order to share files or common equipment such as a printer or a modem. A wireless LAN provides the same functionality of a wired network, but it eliminates the need to install networking cables and other networking equipment. Not only is a wireless LAN easier to deploy, but it also allows for roaming. For example, when using a tablet PC with a Compaq 802.11b Mini PCI card, you can roam from a conference room to an office without being disconnected from the network.

4 Chapter 2 Network Configuring and Planning A wireless LAN can be configured for two different modes of operation. While each method has its advantages, one may be better suited for your needs. Review the following configurations to determine which mode is best for you. Peer-to-Peer Network Base Station Network 2-1 Peer-to-Peer Network A Peer-to-Peer network is also called an ad hoc network. This mode is the easiest to deploy and is ideal for small offices. As a user on this type of network, you are able to share files with other employees, print to a shared office printer, and access the Internet through a shared modem. However, with peer-to-peer networking, your computer is only able to communicate with other wireless clients that are within a certain range and in your wireless workgroup. Characteristics Networked computers send data directly to each other Advantages Simple setup Cost efficiency Disadvantages Communication is limited to those who are located in a certain range

- -

5 2-2 Base Station Network A Base Station network is also called an infrastructure network. The key difference between a wireless Base Station network and a peer-to-peer network is the addition of one extra elementthe base station or access point. Additionally, the wireless Base Station can provide access to an existing wired LAN. This link allows computers on the infrastructure wireless LAN to access the other wired LANs resources and tools, including Internet access, electronic mail delivery, file transfer, and printer sharing. Characteristics Networked computers communicate with each other through a dedicated base station. All data transmitted between the computers on this wireless LAN passes through the base station. Advantages Extended range: The access point extends the range of the wireless LAN. Each computer can communicate with other computers equipped by wireless networks that are within the range of the access point. Roaming: As you move throughout the building, the Compaq 802.11b WLAN Mini PCI card determines the best access point to use to ensure continuous communication with the network. Network connectivity: An access point can provide wireless LAN access to an existing wired network by bridging the two networks together. This gives users of the wireless LAN access to all the functions of a wired networkfrom file server access to electronic mail and the Internet. Disadvantages Because this network mode offers more features, it requires additional components and setup time to deploy. Requirements One base station, such as the:

Report # R0208222Rpt Page 14 of 22 FCC Part 15 Subpart C Report AMBIT Microsystems Corporation FCC ID: MCLT60H570 9 - RADIATED EMISSION 9.1 Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in field of EMC. The factors contributing to uncertainties are spectrum analyzer, cable loss, antenna factor calibration, antenna directivity, antenna factor variation with height, antenna phase center variation, antenna factor frequency interpolation, measurement distance variation, site imperfections, mismatch (average), and system repeatability. Based on NIS 81, The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of a radiation emissions measurement at BACL is +4.0 dB. 9.2 Test Setup The radiated emission tests were performed in the open area 3-meter test site, using the setup in accordance with the ANSI C63.4-2000. The specification used was the FCC 15 Subpart C limits. The EUT was installed in the laptop. The laptop notebook was placed on the center of the back edge on the test table. The modem was placed on the one side of the laptop while the printer was on the other side. The rear of the laptop and peripherals were placed flushed with the rear of the tabletop. The spacing between the peripherals was 10 centimeters. External I/O cables were draped along the edge of the test table and bundle when necessary. The laptop was connected with 120Vac/60Hz power source. 9.3 Spectrum Analyzer Setup According to FCC Rules, 47 CFR 15.33 (a) (1), the system was tested to 25000 MHz. During the radiated emission test, the spectrum analyzer was set with the following configurations:

Start Frequency ........................................................... 30 MHz Stop Frequency ........................................................... 25000 MHz Sweep Speed ............................................................... Auto IF Bandwidth .............................................................. 1 MHz Video Bandwidth ........................................................ 1 MHz Quasi-Peak Adapter Bandwidth.................................. 120 kHz Quasi-Peak Adapter Mode.......................................... Normal Resolution Bandwidth................................................. 1MHz Report # R0208222Rpt Page 15 of 22 FCC Part 15 Subpart C Report AMBIT Microsystems Corporation FCC ID: MCLT60H570 9.4 Test Procedure For the radiated emissions test, both the laptop and all peripheral power cords were connected to the AC floor outlet since the power supply used in the laptop did not provide an accessory power outlet. Maximizing procedure was performed on the six (6) highest emissions to ensure EUT compliance is with all installation combinations. All data was recorded in the peak detection mode. Quasi-peak readings was performed only when an emission was found to be marginal (within -4 dBV of specification limits), and are distinguished with a

"Qp" in the data table. 9.5 Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain from the Amplitude reading. The basic equation is as follows:

Corr. Ampl. = Indicated Reading + Antenna Factor + Cable Factor - Amplifier Gain The Margin column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of -7dBV means the emission is 7dBV below the maximum limit for Subpart C. The equation for margin calculation is as follows:

Margin = Corr. Ampl. Subpart C Limit 9.6 Summary of Test Results According to the data in section 11.7, the EUT complied with the FCC Title 47, Part 15, Subpart C, section 15.205, 15.207, and 15.247, and had the worst margin of:

Based on NIS 81, The Treatment of Uncertainty in EMC Measurements, the best estimate of the uncertainty of any conducted emissions measurement at BACL is +2.4 dB. 10.2 Test Setup The conducted emission tests were performed in the open area 3-meter test site, using the setup in accordance with the ANSI C63.4-2000. The specification used was the FCC 15 Subpart B limits. The EUT was installed in the laptop. The laptop notebook was placed on the center of the back edge on the test table. The modem was placed on the one side of the laptop while the printer was on the other side. The rear of the laptop and peripherals were placed flushed with the rear of the tabletop. The spacing between the peripherals was 10 centimeters. External I/O cables were draped along the edge of the test table and bundle when necessary. The laptop was connected with 120Vac/60Hz power source. 10.3 Spectrum Analyzer Setup The spectrum analyzer was set with the following configurations during the conduction test:

Start Frequency............................................................................... 450 kHz Stop Frequency............................................................................... 30 MHz Sweep Speed................................................................................... Auto IF Bandwidth.................................................................................. 10 kHz Video Bandwidth............................................................................ 10 kHz Quasi-Peak Adapter Bandwidth ..................................................... 9 kHz Quasi-Peak Adapter Mode.............................................................. Normal 10.4 Test Procedure During the conducted emission test, the power cord of the host system was connected to the auxiliary outlet of the first LISN. Maximizing procedure was performed on the six (6) highest emissions of each modes tested to ensure EUT is compliant with all installation combination. All data was recorded in the peak detection mode. Quasi-peak readings were only performed when an emission was found to be marginal (within -4 dBV of specification limits). Quasi-peak readings are distinguished with a "Qp".
