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 determined 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:
ŸReorient or relocate the receiving antenna
ŸIncreasethe separation betweenthe equipment and receiver
ŸConnect the equipment into an outlet on a circuit different from that to which the
receiver is connected
ŸConsult the dealer or an experienced radio/TV technician for help
You are cautioned that changes or modifications not expressly approved bythe party
responsible for compliance could void your authority to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the following
twoconditions:
1. This device may not cause harmful interference, and

Introduction
Congratulations on choosing an InstantWave Wireless Ethernet Client (WEC).
This guide gives instructions on installing the WEC and using the configuration
program.
The InstantWave WEC is part of a family of easy to use high-performance wireless
communication products. The family products also include:
•InstantWave AP (NWH660)
•InstantWave PC Card (NWH610)
•InstantWave PCI Card (NWH630)
The InstantWave WEC provides a wireless connection to the Internet or toshared
resources for an Ethernet-enabled device. Once the WEC has been set up, all that
is required is a simple cross-over Ethernet cable between the WEC and the device
to be connected, e.g. notebook computer. Ad hoc mode allows Ethernet-enabled
devices to communicate wirelessly WEC to WEC
System Requirements
System requirements to install and operate the InstantWave WEC are:
•An Ethernet adapter
•A PC runningWindows 95/98/Me/NT4.0/2000/XP (only required when
configuration of the WEC’s network properties is necessary)
Placement Guidelines
A few tips to mention that are particularly significant in a radio wave
communications system:
1. Radio waves reflect or refract from buildings, walls, metal furniture, or other
objects. This could result in performance degradation due to the fluctuation of
the received signal.
2. Microwave ovens use the 2.45 GHz frequency band. InstantWave also
functions in the 2.4 ~ 2.5 GHz band, and therefore shares some of the band
with microwave ovens. This means that when a nearby microwave oven is in
use, it may interfere with InstantWave signals, resulting in performance
degradation on the wireless network.
For the best performance, follow the guidelines below in placing the product:
•Place as high as possible, in as open an area as possible
2InstantWave 11Mbps Wireless Ethernet Client
•Avoid placing the WEC (especially the antenna) close to metal objects (e.g.
file cabinets, metal cubicles, etc.)
•Keep WECs as far away as possible from microwave ovens (10 meters min. is
advisable)
How to Use this Guide
The Installation Guide gives complete instructions for installation of the
InstantWave Wireless Ethernet Client (WEC).
Use the WEC COMFig tool , see page 7, to change the default WEC settings. The
WEC COMFig tool permits basic WEC offline configuration from a PC via an RS-
232cable/COM port connection.
Terminology Used in this Guide
Domain Name/SSID
A “Domain” is most commonly used to refer to a group of computers whose
hostnames share a common suffix. The domain is usually defined by the network
administrator as a segment/subnet of a large network and may be made up of
overlapping wireless cells. Wireless nodes can roam freely within the same
domain without disconnecting from the network.
RegulatoryDomain
InstantWave 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 (2.471GHz –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 InstantWave in a country not listed above,
check with your government’s regulating body to find the correct frequency band
to use. All InstantWave 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. In order to decode the data transmission, each wireless client on the
network must use identical keys.

Application Scenarios
Infrastructure Network
An Infrastructure network is formed by several stations and one or more Access
Points (APs), with the stations within a set distance from the AP. Figure 1depicts
a typical Infrastructure network topology.

Ad Hoc Network
An Ad hoc network is formed by a number of wireless stations (without an Access
Point) communicating via radio waves. For the users, the shared resources on the
wireless network appear 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.

WEC Configuration Tool Installation
Before adding a WEC into an existing network, you may need to set basic
parameters, e.g. domain name (SSID), security setting (WEP), etc. in order to make
it compatible with the existing network.
Follow the steps below to connect the WEC to a PC for configuration:
step1. Connect the supplied RS-232 cable to the COM port on the WEC and
connect the other end to a serial port (COM port) on the PC
step2. Connect the power block to the electricity outlet and then to the WEC
DC5V port
step3. Insert the InstantWave WEC floppy disk into the floppy disk drive and
click Start/Run. Type a:/setup.exe
step4. Follow the on-screen instructions to complete the WEC COMFig Tool
