a Class B digital device, pursuant to part 15 of the FCC Rules. These

limits are designed to provide reasonable protection against harmful

interference in a residential installation. This equipment generates, uses

and can radiate radio frequency energy and, if not installed and used in

accordance with the instructions, may cause harmful interference to

radio communications. However, there is no guarantee that interference

will not occur in a particular installation. If this equipment does cause

harmful interference to radio or television reception, which can be de-

termined by turning the equipment off and on, the user is encouraged to

try to correct the interference by one or more of the following measures:

 Reorient or relocate the receiving antenna.

 Increase the separation between the equipment and receiver.

 Connect the equipment into an outlet on a circuit different from that

to which the receiver is connected.

 Consult the dealer or an experienced radio/TV technician for help.

You are cautioned that changes or modifications not expressly ap-

proved by the party responsible for compliance could void your

authority to operate the equipment.

FCC Radiation Exposure Statement

This equipment complies with FCC radiation exposure limits set forth

for an uncontrolled environment.

This equipment should be installed and operated with minimum dis-

tance 20cm between the radiator & your body.

CE Mark Warning

This is a Class B product. In a domestic environment, this product may

cause radio interference, in which case the user may be required to

take adequate measures.

Introduction

Thank you for purchasing the 54G WLAN card. This high-speed

Wireless LAN card provides you with an innovative wireless net-

working solution. The Card is easy to set up and use. With this

innovative wireless technology, you can share files and printers on the

network—without inconvenient wires!

Features

• 54Mbps solution in the 2.4GHz band, compliant with the

IEEE 802.11b and draft 802.11g standards

• Wi-Fi certifiable for IEEE 802.11b interoperability

• Wire-free access to networked resources from anywhere

beyond the desktop

• Delivers data rate up to 54 Mbps

• Antenna is built in to the card with LEDs indicating Power

and Link

• Ensures great security by providing the Wired Equivalent

Privacy (WEP) defined in the IEEE 802.11 standard

• Lowest CPU utilization design that leaves system resources

available for other functions

• Seamless Microsoft XP zero-config integration with ad-

vanced utilities and common GUI for legacy OSs

• Driver support Window XP, 2000, ME & 98

What is Wireless LAN?

Wireless Local Area Network (WLAN) systems offer a great

number of advantages over traditional wired systems. WLANs are

flexible and easy to setup and manage. They are also more eco-

nomical than wired LAN systems.

Using radio frequency (RF) technology, WLANs transmit and re-

ceive data through the air. WLANs combine data connectivity

with user mobility. For example, users can roam from a confer-

ence room to their office without being disconnected from the

LAN.

Using WLANs, users can conveniently access shared information,

and network administrators can configure and augment networks

without installing or moving network cables.

WLAN technology provides users with many convenient and cost

saving features:

• Mobility: WLANs provide LAN users with access to real-

time information anywhere in their organization, providing

service opportunities that are impossible with wired net-

works.

• Ease of Installation: Installing is easy for novice and ex-

pert users alike, eliminating the need to install network

cables in walls and ceilings.

• Scalability: WLANs can be configured in a variety of to-

pologies to adapt to specific applications and installations.

Configurations are easily changed and range from peer-to-

peer networks suitable for a small number of users to full

infrastructure networks of thousands of users roaming over

a broad area.

WLAN Modes

Wireless LANs can be configured in one of two ways:

Ad-hoc

Networking Also known as a peer-to-peer network, an ad-hoc net-

work is one that allows all workstations and computers

in the network to act as servers to all other users on

the network. Users on the network can share files,

print to a shared printer, and access the Internet with a

shared modem. However, with ad-hoc networking,

users can only communicate with other wireless LAN

computers that are in the wireless LAN workgroup, and

are within range.

Infrastructure

Networking Infrastructure networking differs from ad-hoc network-

ing in that it includes an access point. Unlike the ad-

hoc structure where users on the LAN contend the

shared bandwidth, on an infrastructure network the

access point can manage the bandwidth to maximize

bandwidth utilization.

Additionally, the access point enables users on a wire-

less LAN to access an existing wired network, allowing

wireless users to take advantage of the wired networks

resources, such as Internet, email, file transfer, and

printer sharing.

Infrastructure networking has the following advantages

over ad-hoc networking:

• Extended range: each wireless LAN computer

within the range of the access point can commu-

nicate with other wireless LAN computers within

range of the access point.

• Roaming: the access point enables a wireless

LAN computer to move through a building and

still be connected to the LAN.

• Wired to wireless LAN connectivity: the access

point bridges the gap between wireless LANs and

their wired counterparts.

Notes on wireless LAN configuration

When configuring a wireless LAN (WLAN), be sure to note the

following points:

• Optimize the performance of the WLAN by ensuring that

the distance between access points is not too far. In most

buildings, WLAN cards operate within a range of 100 ~

300 feet, depending on the thickness and structure of the

walls.

• Radio waves can pass through walls and glass but not

metal. If there is interference in transmitting through a wall,

it may be that the wall has reinforcing metal in its structure.

Install another access point to circumvent this problem.

• Floors usually have metal girders and metal reinforcing

struts that interfere with WLAN transmission.

This concludes the first chapter. The next chapter deals with the

hardware installation of the 54G WLAN card.
