The WLAN device operates in the 2.4GHz ISM band and the 5 GHz lower, middle, and upper UNII bands.

Microwave ovens may interfere with the operation of WLAN devices since they operate in the same 2.4GHz frequency range as IEEE802.11b/g devices. Interfer- ence by microwaves does not occur with IEEE802.11a radio which operates in the 5 GHz RF band.

Wireless devices that transmit in the 2.4GHz range may interfere with operation of WLAN devices in IEEE802.11b/g modes. Symptoms of interference include reduced throughput, intermittent disconnects, and many frame errors. It is HIGHLY recommended that these interfering devices be powered off to ensure proper operation of the WLAN device.

DEACTIVATING THE WLAN DEVICE

Deactivation of the WLAN device may be desired in certain circumstances (to extend battery life) or where certain environments require it (i.e. hospitals, clinics, airplanes, etc.). Fujitsu mobile computers employ two methods with which to deactivate the WLAN device:

Using the Wireless On/Off Switch, or,

In Windows, using the WLAN icon in the taskbar.

Deactivation using the Wireless On/Off Switch

The WLAN device can be deactivated quickly and effi- ciently by sliding the Wireless On/Off Switch to the Off position (to the left). (Figure A-3)

The wireless On/Off switch has no effect on non-Wire- less LAN models.

Deactivation using the icon in the taskbar

1.Right-click the WLAN icon in the taskbar at the bottom right of your screen.

2.Choose Disconnect from a network.

ACTIVATING THE WLAN DEVICE

Activation of the WLAN device can be accomplished using the same methods as the deactivation process

Using the Wireless On/Off Switch

In Windows, by right-clicking the WLAN icon then clicking “Connect to a network”

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.
