1 Introduction
The Wireless Client Bridge/Bridge Router/Access Point/WDS (wireless distribution
system) operates seamlessly in the 2.4 GHz frequency spectrum supporting the
802.11b (2.4GHz, 11Mbps) and faster 802.11g (2.4GHz, 54Mbps) wireless standards.
It's the best way to add wireless capability to your existing wired network, or to add
bandwidth to your wireless installation.
NCB-3220 has high transmitted output power and high receivable sensitivity. High
output power and high sensitivity can extend range and coverage to reduce the
roaming between APs to get more stability wireless connection. It also can reduce
the expense of equipment in the same environment.
To protect your wireless connectivity, it can encrypt all wireless transmissions
through 64/128-bit WEP data encryption and also supports WPA/WPA2. The MAC
address filter lets you select exactly which stations should have access to your
network.
This chapter describes the features & benefits, package contents, applications, and
network configuration.

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:
a) Difficult-to-wire environments
There are many situations where wires cannot be laid easily. Historic
buildings, older buildings, open areas and across busy streets make the
installation of LANs either impossible or very expensive.

b) Temporary workgroups
Consider situations in parks, athletic arenas, exhibition centers, disaster-
recovery, temporary offices and construction sites where one wants a
temporary WLAN established and removed.
c) 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.
d) Frequently changed environments
Show rooms, meeting rooms, retail stores, and manufacturing sites where
frequently rearrange the workplace.
e) Small Office and Home Office (SOHO) networks
SOHO users need a cost-effective, easy and quick installation of a small
network.
f) 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.
g) Wired LAN backup
Network managers implement wireless LANs to provide backup for
mission-critical applications running on wired networks.
h) 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 Configuration
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:
a) Ad-hoc (or peer-to-peer) for departmental or SOHO LANs.
b) Infrastructure for enterprise LANs.
a) Ad-hoc (peer-to-peer) Mode
This is the simplest network configuration with several computers
equipped with the PC Cards that form a wireless network whenever they
are within range of one another. In ad-hoc mode, each client is peer-to-
peer, would only have access to the resources of the other client and
does not require an access point. This is the easiest and least expensive
way for the SOHO to set up a wireless network. The image below depicts
a network in ad-hoc mode.

b) Infrastructure Mode
The infrastructure mode requires the use of an access point (AP). In this
mode, all wireless communication between two computers has to be via
the AP. It doesn’t matter if the AP is stand-alone or wired to an Ethernet
network. If used in stand-alone, the AP can extend the range of
independent wireless LANs by acting as a repeater, which effectively
doubles the distance between wireless stations. The image below
depicts a network in infrastructure mode.
