3. Wireless LAN Basics
Wireless LAN (Local Area Networks) systems offer a great number of advantages over a traditional,
wired system. Wireless LANs (WLANs) are more flexible, easier to setup and manage and often more
cost effective than their wired equivalence.
Using radio frequency (RF) technology, WLANs transmit and receive data over the air, minimizing the
need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through
simplified configuration, enable movable LANs.
With wireless LANs, users can access shared information without looking for a place to plug in and
network managers can set up or augment networks without installing or moving wires. Wireless LANs
offer the following productivity, convenience and cost advantages over traditional wired networks:
• Mobility - Wireless LAN systems can provide LAN users with access to real-time information
anywhere in their organization. This mobility supports productivity and service opportunities not
possible with wired networks.
• Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can
eliminate the need to pull cable through walls and ceilings.
• Installation Flexibility - Wireless technology allows the network to go where wires cannot go.
• Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware
might be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle
costs will be significantly lower. Long-term cost benefits are greatest in dynamic environments
requiring frequent moves, adds, and changes.
• Scalability - Wireless LAN systems can be configured in a variety of topologies to meet the needs
of 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 that allows roaming over a broad area.

5. Configuration Utility
Wireless LAN 11 Mbps Wireless LAN USB uses its own management software. All functions controlled
by user are provided by this application. Usually this application starts automatically, Use Start,
Programs, Wireless LAN 11 Mbps Wireless LAN to start the Manager application.
A new icon - should appear in your Icon tray. If the icon is in red, it means that Wireless LAN 11
Mbps NIC configuration is invalid or incomplete. Sometimes icon can be colored in red. This can
happen when driver is in Pseudo BSS mode, and the radio channel, which is used for communication
is defined incorrectly.
Figure 1 Icon tray with a new icon
Double clicking on that icon will show you the screen as shown below.
Figure 2 Management window with “Status” tab open
User can navigate through “sheets”, by clicking or tapping them with a stylus. “OK” button will minimize
window, and “X” button (right upper corner) will close application. Here we explain the use and
meanings of the various screen messages.

Status
Link Status
The field shows associated to available AP with BSSID, MAC ID of USB. When the state is
“Associated “ means normal flow of operation in Infrastructure mode. The PC is connected to access
point. BSSID is shown in the form of hex digits. Networking is available.
Tx/Rx Rate Information
This display the instantaneous wireless Receive and Transmit throughput displayed in
bytes per second. These values are updated every two seconds.
Signal Strength
The Link Quality bar graph is only active when the node is in Infrastructure Mode. The bar graph
displays the quality of the link between the node and its Access Point. A label summarizes the quality
of the link over the bar graph, which can take on one of the following values:
“No Traffic”
“Poor”
“Good”
“Very Good”
“Excellent”
The driver will start looking for a better Access Point if the Link Quality becomes “Poor”. Link Quality
is a measure of receives and transmits errors over the radio.

“CONFIGURATION” tab
The Configuration Tab contains several fields where operating parameters of the driver can be
viewed or changed. Changes to any of the parameters in this panel can be applied to the driver
without the need to reboot the PC.
Figure 3 Management window with "CONFIGURATION" tab open
Station ESS ID
Extended Service Set Identifier (Wireless Network Identifier) is the group name that will be shared by
every member of your wireless network. You will only be able to connect with an Access Point , which
has the same ESS ID.
Wireless LAN
Page 18 Wireless LAN 11 Mbps User manual
Network Mode
This field allows you to select from a list of supported Network “Modes”. The modes displayed will
have two values: “ Ad Hoc”, and “Infrastructure”.
Ad Hoc - This is the 802.11 peer-to-peer mode of operation. In 802.11Ad Hoc only one wireless
“cell” is supported for each different SSID. All communication is done from Client to Client without
the use of an Access Point. 802.11 Ad Hoc networking use the same SSID for establishing the
wireless connection.
Infrastructure - This mode of operation requires the presence of an 802.11 Access Point. All
communication is done via the Access Point, which relays packets to other wireless Clients in
the BSS as well as to nodes on a wired network such as Ethernet.
Preamble
Two different preambles and headers are defined: the mandatory supported Long Preamble
and header, which inter-operates with the current 1 Mbit/s and 2 Mbit/s DSSS specification (as
described in IEEE Std 802.11, and an optional Short Preamble and header. The optional Short
Preamble and header is intended for applications where maximum throughput is desired and
interoperability with legacy and non-short-preamble capable equipment is not a consideration.
That is, it is expected to be used only in networks of like equipment, which can all handle the
optional mode.
TX Rate
The transmission rate at which the data packets are transmitted by client of AP. You can set this
to fixed 1Mbps, fixed 2 Mbps, fixed 5.5 Mbps or fixed 11 Mbps.
“Update” button
This button becomes active only when one of the fields has been modified. Pressing this button
applies the changed values to the driver and saves them to the registry for the next time the PC
boots up.
Wireless LAN
User manual Wireless LAN 11 Mbps Page 19
“ENCRYPTION” tab
Figure 4 Management window with “Encryption” tab open
You may desire an additional measure of security on your wireless network, which can be
achieved by using WEP (Wired Equivalent Privacy) encryption. WEP encrypts each frame
transmitted from the radio using one of the Keys entered from this panel.
When an encrypted frame is received it will only be accepted if it decrypts correctly. This will only
happen if the receiver has the WEP Key used by the transmitter.
To be written to the driver and registry, each key must consists of hex digits which means that only
digit 0-9 and letters A-F are valid entries. If entered incorrectly program will not write keys to a
driver.
Wireless LAN
Page 20 Wireless LAN 11 Mbps User manual
- Key 1 – Key 4
These four fields can be used to manually enter the keys. This may be necessary if you wish
this node to match keys in a different vendor’s product.
Mode
Mandatory:
The WEP encryption will be used, and other station also needs to use WEP encryption in order
to establish a communication with your station. This mode is required to compliant with the
IEEE 802.11b standard.
Optional :
This mode allows your station to communicate with other stations regardless if they
use WEP encryption or not.
Authentication Type
Open System :
Open System is the default authentication algorithm.
Open System authentication is not required to be successful as a STA may decline
to authenticate with any particular other STA.
Shared Key:
Shared Key is only available if the WEP option is implemented.
Shared Key authentication supports authentication of STAs as either a member of those who
know a shared secret key or a member of those who do not. IEEE 802.11 Shared Key
authentication accomplishes this without the need to transmit the secret key in clear; requiring
the use of the WEP privacy mechanism.
- Apply Change
This button updates the driver with the four keys displayed in Key field. The keys are also
written to the registry for permanent storage. This button clears all the bytes in the four keys,
useful when manually entering and you wish to start over.
