1- 5 Applications

The wireless LAN products are easy to install and highly efficient. The
following list describes some of the many applications made possible
through the power and flexibility of wireless LANs:

1. Difficult-to-wire environments

There are many situations where wires can not or not easily be laid. Historic
buildings, older buildings, open areas and across busy streets make the
installation of LANs either impossible or very expensive.

2. Temporary workgroups

Consider situations in parks, athletic arenas, exhibitions, disaster-recovery,
temporary office and construction sites where one wants a temporary WLAN

2

established and removed.

3. The ability to access real-time information

Doctors/nurses, point-of-sale employees, and warehouse workers can
access real-time information while dealing with patients, serving customers
and processing information.

4. Frequently changed environments

Show rooms, meeting rooms, retail stores, and manufacturing sites where
frequently rearrange the workplace.

5. Small Office and Home Office (SOHO) networks

SOHO users need a cost-effective, easy and quick installation of a small
network.

6. Wireless extensions to Ethernet networks

Network managers in dynamic environments can minimize the overhead
caused by moves, extensions to networks, and other changes with wireless
LANs.

7. Wired LAN backup

Network managers implement wireless LANs to provide backup for
mission-critical applications running on wired networks.

8. Training/Educational Facilities

Training sites at corporations and students at universities use wireless
connectivity to ease access to information, information exchanges, and
learning.

1- 6 Network Configurations

To better understand how the wireless LAN products work together to
create a wireless network, it might be helpful to depict a few of the
possible wireless LAN PC card network configurations. The wireless
LAN products can be configured as:

1. Ad-hoc (or peer-to-peer) for departmental or SOHO LANs.

2. Infrastructure for enterprise LANs.

3. IP Sharing for 56K/ISDN TA/Cable/DSL Modem – Connect Internet and your
SOHO network.

Ad-hoc (peer-to-peer) Mode

This is the simplest network configuration that several computers
equipped with the PC Cards that form a wireless network whenever they
are within range of one another (Figure 1-3). In ad-hoc mode, each
client, is peer-to-peer, would only have access to the resources of the
other client and requires no the access point. This is the easiest and

3

least expensive way for the SOHO to set up a wireless network.

Infrastructure Mode

The infrastructure mode requires the use of an access point (AP). In this
mode, all wireless communications between two computers have to be
via the AP no matter the AP is wired to Ethernet network or stand-alone.
If used in stand-alone, the AP can extend the range of independent
wireless LANs by acting a repeater, which effectively doubling the
distance between wireless stations as shown in Figure 1-4.

If wired to an Ethernet network as shown in Figure 1-5, the AP serves
as a bridge and provides the link between the server and the wireless
clients. The wireless clients can move freely throughout the coverage
area of the AP while remaining connected to the server. Since the AP is
connected to the wired network, each client would have access to
server resources as well as to other clients.

Access points have a finite range, on the order of 50 meters indoor and
100 meters outdoors. In a very large facility such as an enterprise, a
warehouse, or on a college campus, it will probably be necessary to
install more than one access point to cover an entire building or campus,
as shown in Figure 1-6. In this scenario, access points hand the client
off from one to another in a way that is invisible to the client, ensuring
roken connectivity. Wireless clients can roam seamlessly between
different coverage areas and remain connected to the network.

Wireless Router and IP Sharing

In infrastructure mode, in addition to acting as a bridge between an
Ethernet and wireless network, the AP can be configured as a wireless
router and IP sharing device for Internet access as shown in Figure 1-7.
You don’t have to buy an expensive router. Nor you have to buy several
modems and setup phone lines. Just share one AP, one Modem, single
dial-up account, and one phone line, dozens of network users can go
surfing the Internet concurrently.

Chapter 2 Installing Drivers & Client Utility

This chapter describes how to install the PC Card drivers and client
utility under Windows 95/98/ME/2000/XP.

2-1 Installation for Windows 95/98/ME/2000

During the installation, Windows 95/98/ME/2000 may need to copy
Windows systems files from the Windows 95/98/ME/2000 installation
diskette or CD-ROM. Therefore you will need a copy of the Windows
95/98/ME/2000 installation diskette or CD-ROM at hand before installing
the driver. On many systems, instead of a CD, the necessary installation
files are archived on the hard disk in C:\WINDOWS \OPTIONS\CABS
directory.

Installation Procedure:

1. Turn on your computer.

2. Be sure that there is no PCMCIA adapter inserted yet.

3. Insert the Wireless LAN Installation CD into your CD-ROM drive. The setup

program should start automatically as shown in Figure 2-1. If it does not start,
you can run it manually by selecting RUN from the Start menu and running
SETUP.EXE from CD-ROM drive.
