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.

Page 18 11Mbps Wireless PC Card User's manual
Link Info
- State
This field is used to display the current state of the driver. 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.
A state of “Scanning ” means that the node is searching for available access point and can not
detect the SSID for an access point within range.
This field will also display an error message if for some reason the driver failed to initialize.
- Rescan
Pressing the rescan button causes the driver to restart and begin its Connection Procedure. The
connection procedure differs depending on the Mode of the driver.
Infrastructure Mode - The driver will scan all available channels continuously until it finds one or
more Access Points that matches its SS ID. At that point it will try and authenticate and associate
with the Access Point.
802.11Ad Hoc Mode - T
he driver will scan for 5 seconds looking for an existing 802.11Ad Hoc
network using the same SS ID. If one is not found the driver will start its own 802.11Ad Hoc network.
- Current Channel and Tx Rate
Shows the channel of the radio and transmit ra
te are being currently used for an active connection.
This value has no meaning when the radio is “Scanning”
- Throughput
These two fields display the instantaneous wireless Receive and Transmit throughput displayed in
bytes per second. These values are updated every two seconds.
- Link Quality
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:
“Poor”
“Weak”
“Fair”
“Good”
“Excellent”
Wireless LAN
User's manual 11Mbps Wireless PC Card Page 19
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.
- Signal Strength
The Signal Strength bar graph is only active when the node is in Infrastructure Mode. The bar
graph displays normalized signal strength as reported by the radio, averaged over all frames over
100 bytes long that are received from the Access Point.

- Mode
This field allows you to select from a list of supported Network “Modes”. The modes displayed will
have three values: “802.11Ad Hoc”, and “I nfrastructure”.
802.11 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.
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 11 Mbps.
PS Mode - Power saving mode.

“ENCRYPTION” tab
Figure 5 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.
This panel allows the entry of four keys for 64-bit encryption and one set of 128-bit key according
to WEP function select. 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.
Alternatively a Pass-phrase can be entered which is used as a “seed” to randomly generate the
four keys. This saves considerable time since the same keys must be entered into each node on
the wireless network.
Wireless LAN
User's manual 11Mbps Wireless PC Card Page 23
- 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. These fields also display the keys when
they are generated using a Pass-phrase.
- Default Tx Key
This button updates the driver with the four keys displayed in Key1 through Key4. The keys are
also written to the registry for permanent storage. For 128 bit encryption, this button will be
invisible.
- Apply
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.
