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 cannot or not easily be laid. Historic

2

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
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.

3

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

Figure 1-3 A wireless Ad-hoc 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.

4

Figure 1-4 Infrastructure Mode

Extended-range independent WLAN using AP as repeater

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.

Figure 1-5 Single AP bridge

5

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 the
connectivity. Wireless clients can roam seamlessly between different
coverage areas and remain connected to the network.

Figure 1-6 Multiple-AP and roaming

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.

Card antenna is attached to the end
of the PC Card. For best use of the
antenna:
Keep the area around the antenna
clear from materials that could block
radio transmission, such as metal
objects, electronic devices, and
cordless telephones.
If your signal is weak, change the
direction of the antenna slightly.
If necessary, move your notebook
computer a few inches to find a better
signal.
Use the Link Quality and Signal Strength

display in the Client Utility to determine the
best location and orientation for a network
connection.
