Introduction

Congratulations on choosing Wireless Ethernet Client (WEC). This guide gives
instructions on installing WEC and using the configuration program.

WEC provides a wireless connection to the Internet or to shared resources for an
Ethernet-enabled device. Once WEC has been set up, all that is required is a cross­over Ethernet cable to WEC to another device, such as a notebook computer. Ad
hoc mode provides Ethernet-enabled devices with the ability to communication
wirelessly between two WEC units.

System Requirements

You will need the following equipment to install and operate WEC:

• An Ethernet adapter.

• A PC running Windows 95/98/Me/NT4.0/2000/XP (only required when

you need to configure WEC’s network properties).

Placement Guidelines

The following tips are particularly significant for radio wave communications
systems:

1. Radio waves reflect or refract from buildings, walls, metal furniture, and other
objects. This could result in a degradation of performance due to the
fluctuations in the received signal.

2. Microwave ovens use the 2.45 GHz frequency bandwidth. WEC also operates
in the 2.4 – 2.5 GHz bandwidth, and therefore shares some of the bandwidth
used by microwave ovens. This means that when a nearby microwave oven is
in use, it may interfere with signals emanating from a WEC unit, resulting in a
degradation of the wireless network’s performance.

To achieve the best performance, follow the guidelines given below when placing a
WEC unit:

• Place the unit as high as possible, and in as open an area as is possible

• Avoid placing the WEC (especially the antenna) close to metal objects (such

as file cabinets, metal cubicles, etc.).

• Keep WEC units as far away as possible from microwave ovens (a minimum
of 10 meters is recommended).

How to Use this Guide

The Installation Guide gives complete instructions for installing Wireless Ethernet
Client (WEC).

Use the WEC COMFig tool— see page 8— to change the default WEC settings.
The WEC COMFig tool permits basic WEC offline configuration from a PC via an
RS-232 cable/COM port connection.

Terminology Used in this Guide

Domain Name/SSID

A “Domain” is most commonly used to refer to a group of computers with
hostnames that share a common suffix. The domain is usually defined by the
network administrator as a segment/subnet of a large network, and may comprise
overlapping wireless cells. Wireless nodes can roam freely within the same domain
without disconnecting from the network.

Regulatory Domain

WEC products use the unlicensed ISM (Industrial, Scientific, Medical) band to
communicate through radio waves. Different countries offer different radio
frequencies to be used as the ISM band. There are four frequency bands defined by
IEEE 802.11: Japan (2.471 GHz – 2.497 GHz), USA, Extended Japan, Canada, and
Europe (2.4 GHz – 2.4835 GHz), Spain (2.445 GHz – 2.475 GHz), and France
(2.4465 GHz – 2.4835 GHz). To use WEC in a country not listed above, check
with your government’s regulatory agency to determine the correct frequency band
to use. All WEC products are supplied preset to the country of sale’s frequency
band.

WEP

WEP stands for Wired Equivalent Privacy. It is an encryption scheme that provides

secure wireless data communication. WEP uses a 40-bit or 128-bit key to encrypt
data. Each wireless client on the network must use identical keys to decode a data
transmission.

Application Scenarios

Infrastructure Network

An Infrastructure Network is formed by several stations and one or more Access
Points (APs), in which the stations are within a set distance from the AP. Figure 1
depicts the topology for a typical Infrastructure Network.
