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 stre ets make the
installation of LANs either impossible or very expensive.
b) Temporary workgroups
Consider situations in parks, athletic arenas, exhibition centers, disasterrecovery, 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
8
ECB-1220R 11b/g Wireless Client Bridge/AP/Router/Repeater Version 1.1
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.
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 the y
are within range of one another. In ad-hoc mode, each client is peer-topeer, would only have access to the resources of the other client and
does not require an access point. This is the ea siest and least expensive
way for the SOHO to set up a wireless network. The image below depicts
a network in ad-hoc mode.
9
ECB-1220R 11b/g Wireless Client Bridge/AP/Router/Repeater Version 1.1
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 v ia
the AP. It doesn’t matter if the AP i s 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.

WPA / WPA2 / WPA2 Mixed Passphrase
Encryption: Select WPA, WPA2 or WPA2_Mixed from the drop-down list if your
wireless network uses this encryption. WPA (Wi-Fi Protected Access) was designed
to improve upon the security features of WEP (Wired Equivalent Privacy). The
technology is designed to work with existing Wi-Fi products that have been enabled
with WEP. WPA provides improved data encryption through the Temporal Integrity
Protocol (TKIP), which scrambles the keys using a hashing algorithm and by adding
an integrity checking feature which makes sure that keys haven’t been tampered with.
WPA Authentication Mode: Select the Personal (Pre-Shared Key) radio button.
WPA/WPA2: Select TKIP, AES or both as the cipher suite.
Pre-Shared Key Format: Select Passphrase from the drop-down list.
Pre-Shared Key: Enter the pass phrase; this should be between 8 and 63 characters.
Click on the Apply Changes button to confirm the changes. This device will
