This manual describes the procedures required to prop- erly set up and configure the integrated Wireless LAN Mini-PCI device (referred to as "WLAN device" in the rest of the manual). Before using the WLAN device, read this manual carefully to ensure it's correct operation. Keep this manual in a safe place for future reference.

Wireless LAN Device Covered by this Document

This document is applicable to systems containing the Intel PRO/Wireless 3945ABG Network Connections (802.11a+b/g)

Characteristics of the WLAN Device

■The WLAN device is a Mini-PCI card attached to the main board of the mobile computer.

■The WLAN device operates in license-free RF bands, eliminating the need to procure an FCC operating license. The WLAN operates in the 2.4GHz Industrial, Scientific, and Medical (ISM) RF band and the lower, middle, and upper bands of the 5GHz Unlicensed National Information Infrastructure (UNII) bands.

■The Intel PRO/Wireless 3945ABG WLAN device is capable of three operating modes, IEEE802.11a, IEEE802.11b and IEEE802.11g.

■The WLAN device is Wi-Fi certified and operates at the maximum data transfer rate of 54 Mbps in IEEE802.11a or IEEE802.11g mode and 11 Mbps in IEEE802.11b mode.

■The WLAN device supports the following encryption methods - WEP, TKIP, CKIP, and AES encryption.

■The Wireless LAN device is compliant with the follow- ing standards: WPA, WPA2, CCX1.0, CCX2.0, and CCX3.0.

WIRELESS LAN MODES USING THIS DEVICE

Ad Hoc Mode

(See Figure A-1)"Ad Hoc Mode" refers to a wireless network architecture where wireless network connec- tivity between multiple computers is established without a central wireless network device, typically known as Access Point(s). Connectivity is accomplished using only client devices in a peer-to-peer fashion. That is why Ad Hoc networks are also known as peer-to-peer networks. Ad Hoc networks are an easy and inexpensive method for establishing network connectivity between multiple computers.

Ad Hoc mode requires that the SSID, network authenti- cation, and encryption key settings are identically configured on all computers in the Ad Hoc network.

Access Point (Infrastructure) Mode

(See Figure A-2)Infrastructure mode refers to a wireless network architecture in which devices communicate with wireless or wired network devices by communi- cating through an Access Point. In infrastructure mode, wireless devices can communicate with each other or with a wired network. Corporate wireless networks operate in infrastructure mode because they require access to the WLAN in order to access services, devices, and computers (e.g., file servers, printers, databases).

How to Handle This Device

The WLAN device comes pre-installed in your mobile computer. Under normal circumstances, it should not be necessary for you to remove or re-install it. The Oper- ating System that your mobile computer comes with has been pre-configured to support the WLAN device.

■The Intel PRO/Wireless 3945ABG WLAN device sup- ports IEEE802.11a, IEEE802.11b and IEEE802.11g.

A6020 specifications

The Fujitsu Siemens Computers A6020 is a desktop PC that exemplifies the combination of power and efficiency, catering primarily to small businesses and home office users. Launched in the early 2000s, it was designed to meet the growing demand for reliable computing solutions with a focus on affordability without compromising performance.

At its core, the A6020 is powered by a range of Intel processors, offering a variety of options to suit different user needs. Depending on the configuration, it can be equipped with Intel Pentium 4 or Intel Celeron processors, providing a solid balance of speed and efficiency for everyday tasks such as word processing, spreadsheets, and basic multimedia applications.

One of the standout features of the A6020 is its flexible expandability. With multiple expansion slots, users can easily upgrade their system to enhance performance, whether by adding more RAM or incorporating additional storage solutions. The machine typically supports up to 2GB of DDR memory, which was a considerable amount at the time, allowing users to run multiple applications simultaneously with ease.

In terms of storage, the A6020 comes with a variety of hard drive options, usually ranging from 40GB to 120GB. This ample capacity makes it suitable for users who need to store documents, presentations, and media files without immediate concern for running out of space. Moreover, the inclusion of optical drives gives users the capability to read and write CDs, a valuable function during an era where physical media was still prevalent.

Networking capabilities are also a key feature of the A6020. Equipped with Ethernet ports and optional wireless capabilities, it allowed users to easily connect to local networks and the internet, facilitating communication and data sharing in an increasingly digital workspace.

The design of the A6020 prioritizes user-friendliness, featuring a simple yet effective layout that allows for easy access to components and ports. The compact form factor ensures that it fits comfortably in various workspace environments, promoting efficient use of space.

Overall, the Fujitsu Siemens Computers A6020 represents a thoughtful combination of performance, expandability, and usability, making it a suitable choice for individuals and small businesses looking for a reliable desktop solution during its time in the early 2000s.
