What is Wireless LAN?
Wireless Local Area Network (WLAN) systems offer a great number of
advantages over traditional wired systems. WLAN is flexible and easy to
setup and manage. They are also more economical than wired LAN
systems.
Using radio frequency (RF) technology, WLAN transmit and receive data
through the air. WLAN combine data connectivity with user mobility. For
example, users can roam from a conference room to their office without
being disconnected from the LAN.
Using WLAN, users can conveniently access-shared information, and
network administrators can configure and augment networks without
installing or moving network cables.
WLAN technology provides users with many convenient and cost saving
features:
Mobility: WLAN provide LAN users with access to real-time
information anywhere in their organization, providing service
opportunities that are impossible with wired networks.
Ease of Installation: Installing is easy for novice and expert users
alike, eliminating the need to install network cables in walls and
ceilings.
Scalability: WLAN can be configured in a variety of topologies to
adapt to specific applications and installations. Configurations are
easily changed and range from peer-to-peer networks suitable for
a small number of users to full infrastructure networks of
thousands of users roaming over a broad area.
13
AT-WCL452 User’s Guide
Wireless LAN Modes
Wireless LANs can be configured in one of two ways:
Ad-hoc
Networking
Also known as a peer-to-peer network, an ad-hoc network is one that
allows all workstations and computers in the network to act as servers to
all other users on the network. Users on the network can share files, print
to a shared printer, and access the Internet with a shared modem.
However, with ad-hoc networking, users can only communicate with
other wireless LAN computers that are in the wireless LAN workgroup,
and are within range.
Infrastructure
Networking
Infrastructure networking differs from ad-hoc networking in that it
includes an access point. Unlike the ad-hoc structure where users on the
LAN contend the shared bandwidth, on an infrastructure network the
access point can manage the bandwidth to maximize bandwidth
utilization.
Additionally, the access point enables users on a wireless LAN to access
an existing wired network, allowing wireless users to take advantage of
the wired networks resources, such as Internet, email, file transfer, and
printer sharing.
Infrastructure networking has the following advantages over ad-hoc
networking:
Extended range: each wireless LAN computer within the range of
the access point can communicate with other wireless LAN
computers within range of the access point.
Extended mobile connectivity: the access point enables a wireless
LAN computer to move through a building and still be connected
to the LAN.
Wired to wireless LAN connectivity: the access point bridges the
gap between wireless LANs and their wired counterparts.
14
AT-WCL452 User’s Guide
Wireless LAN Configuration
When configuring a wireless LAN (WLAN), be sure to note the following
points:
Optimize the performance of the WLAN by ensuring that the
distance between access points is not too far. In most buildings,
WLAN Adapters operate within a range of 100 ~ 300 feet,
depending on the thickness and structure of the walls.
Radio waves can pass through walls and glass but not metal. If
there is interference in transmitting through a wall, it may be that
the wall has reinforcing metal in its structure. Install another
access point to circumvent this problem.
Floors usually have metal girders and metal reinforcing struts that
interfere with WLAN transmission.

Figure 39 Wireless LAN Configuration Utility - Configuration window
The profile setting allows you to save configurations in different
profiles for different working environments. The default profile
will contain the initial configuration setting when you install the
Card. Under the Operating Mode drop-box, you may choose
either Infrastructure or Ad-Hoc. The Infrastructure mode allows a
wireless adapter to communicate with a wired network
employing an Access Point, while the Ad-Hoc mode allows
wireless-to-wireless, peer-to-peer communication. If you choose
Infrastructure, the SSID should have the same name as the Access
Point. If you choose Ad-Hoc, all clients should share the same SSID
name. You may also select which Transfer Rate you wish to use: 1,
2, 5.5, 11Mbps or Auto Rate. Under Power Saving Mode, you can
select Enabled to allow your adapter to go to sleep mode while
the adapter does not proceed the data transmission. You may
also select Disabled to make the adapter never go to sleep mode.
3. Click Apply to save the settings.

7. Click on the Encryption tab.
Under the drop-box, you can choose to have WEP encryption
Disabled, 64-Bit, or 128-Bit. Wired Equivalent Privacy (WEP) is an
encryption scheme used to protect wireless data communication.
The Disabled setting prevents the sharing of data with other
computers on the WEP network. For data sharing to be enabled,
select the level of encryption desired, either 64 or 128-bit.

You can choose the fragmentation threshold to define the
maximum data frame size your adapter will transmit. When the
packet error rate is high, you may set the threshold value to
transmit shorter frames. You may select RTS/CTS threshold to
define when will your adapter send out RTS/CTS frames to reserve
bandwidth for transmission. By using the RTS/CTS function, you
may request bandwidth from AP to allow you have better chance
to send out your data. For Security, it is only applicable while WEP
is enabled.
For the Authentication Type, the current supported algorithms
are Open System, Shared Key, and Auto. The algorithm will be
invoked when associated to Access Point. To associate to the
desired Access Point you must set the same algorithm as the one
of the desired Access Point. When select Auto mode, the driver
can auto detect the Authentication Type of the Access Point you
are going to associate. You can also select Preamble Type which is
for framing synchronization. The possible setting are long and
Short. The setting must be the same as the setting of the Access
Point you are going to associate.

FAQs
1. What is IEEE 802.11 standard?
The IEEE 802.11 is a wireless LAN industry standard, and the
objective of IEEE 802.11 is to make sure that different
manufactures wireless LAN devices can communicate to each
other.
2. What is WEP?
As described in the IEEE 802.11 standard, WEP (Wired Equivalent
Privacy) is a data privacy mechanism based initially on a 40 bit
shared key algorithm.
3. Why can’t Windows recognize the AT-WCL452 Wireless LAN
Card?
Please make sure that the LAN Card is inserted into the PCMCIA
slot of your notebook properly (check this when the notebook is
powered off).
Please check if PC Card support is installed. Double-click the PC
Card icon on Control Panel. If PC Card support is not activated,
you should activate it now.
4. In Infrastructure mode, my notebook cannot communicate with
the others notebooks on the network.
First, make sure that the SSID is same as the others notebook.
Check if the WEP is enabled on the Access Point, if it is, set your
Adapter’s WEP to the same setting as the Access Point.
Also check the Access Point Authentication Type and Preamble
Type and match those settings.
