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 cross-

over 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.

Ad Hoc Network

An Ad Hoc Network is formed by a number of wireless stations (without an

Access Point) that communicate via radio waves. The shared resources on the

wireless network appear to users exactly as they would on a regular wired network.

The wireless operation of the network is totally transparent. Figure 2depicts a

typical Ad Hoc Network scenario.
