2. 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.

During the installation of your Wireless LAN Card, configuration utility is also installed. You can see
the icon at the right bottom of your screen. Double clicking on that icon will show you the screen as
shown below.
Figure 1 Management window with “Status” tab open
Here we explain the use and meanings of the various screen messages.
The first three fields show your wireless network card state.
Link status – indicates link accesibility. There are several values, that can be shown in this part of the
window:
Connect to AP – normal flow of operation in Infrastructure mode. The PC is connected to
access point. Networking is available.
No status… - the manager is retrieving information from the driver. If this text box value stays more
than several seconds, it means that there are no access points or other workstations (if
communicating in AdHoc mode), or that the GemTek NIC card is plugged out of PC.
Scanning for AP – driver scans wireless network searching for available access point in
Infrastructure mode.
Not joined or AdHoc mode – normal flow of operation in AdHoc mode. Networking is available.
If the Infrastructure mode is defined, it means that driver has failed to find access point in the
accessible range.
Error – means critical driver error. This error is usually caused by hardware misconfiguration (for
example the card with similar chipset inserted in PC card bay, but not fully compatible with
GemTek NIC).

User manual WL-211 PC Card Page 13
Input bytes/sec – shows the incoming (received) data speed, the progress bar below, means receiver
load.
Output bytes/sec – shows the outgoing (sent) data speed, the progress bar below, shows transmitter
load.
Signal strength : bar shows signal strength level. The higher blue bar is, the more powerful is radio
signal received by Gemtek PC card. This indicator helps to find the most comfortable
antenna/workstation position for quality network operation.
Link quality: The measured signal level gives the overall Link Quality and Connection Status.

“CONFIGURATION” tab
You can change the configuration by clicking on the Change Configuration. When you click on the
Change Configuration, you see the screen given below.
Figure 2 Management window with "CONFIGURATION" tab open
Five changeable fields in this field show desired GemTek NIC configuration.
The fields are following:
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.
Network mode shows one of these network modes:
•AdHoc -this is the 802.11 peer-to-peer mode of operation. In Ad Hoc only one wireless "cell" is
supported for each different ESS ID. All communication is done from Client to Client without
the use of an Access Point.
•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 (Basic Service Set) as well as to nodes on a wired network such as Ethernet.

Wireless LAN
User manual WL-211 PC Card Page 15
Encapsulation shows one of two different network packet forming modes
•Encapsulated This setting takes the entire Ethernet frame, including the Ethernet Header, and
puts it into an 802.11 frame. This setting is here for compatibility with some older 802.11
implementations and should not normally be used.
•RFC1042 where the DIX Ethernet frames are converted using SNAP header based on
RFC1042. This mode will also convert any RFC1042 SNAP header frames to DIX Ethernet
frames before transmission to the Ethernet interface.
•802.1h where the DIX Ethernet frames are tunneled using a full selective translation table. This
mode does not convert RFC1042 SNAP header frames to DIX Ethernet before transmission to
the Ethernet interface
It is required to select encapsulation mode corresponding to the one your access point or other
workstations use. If the encapsulation mode is incorrect, the PC will join to access point or will
be seen by other workstations, but network operation will not work.
Channel – shows radio channel number used for networking. Only Access Points and Ad Hoc nodes
can create a BSS therefore this parameters is not active if Mode is Infrastructure. Infrastructure Client
nodes will always go the same channel as their AP. Please see the table for the requirements of
different countries and the channel frequency.
TX Rate: The transmission rate at which the data packets are transmitted by the client or AP. You can
set this to Auto select I or 2Mbps, Fixed 1 Mbps, Fixed 2 Mbps, Fixed 5.5 Mbps, Fixed 11 or Full Auto
(I to 11 Mbps).
Important:
You must know the T
X
Rate that your AP can support. Failure to which may
cause the undesired results.

5. WEP Security:
To provide the secure communication over the wireless medium, we have provided the WEP (Wired
Equivalent Privacy) key. There are two ways of generating this key. This key is an important in
protecting the illegal access to the wireless networks.
You have to set the key at the Access Point also. And all the users who want to contact/share the
resources must type the same key. The WEP key works in the infrastructure mode only. There are
two options in case of the WEP. You can select either of Disabled, and mandatory. If you select
Disabled, the communications between clients and clients and AP is not secure. If you select
mandatory, you need to setup the AP also and enter the same Key for communicating other clients
associated with the AP or with AP itself.
WEP Key Generation:
There are two ways of generating the WEP key. The first is by entering any text in the Passphrase.
And click on Generate. It will generate four WEP keys as Key 1, Key 2, Key 3, and Key 4. You can
select any key for the security. If you do not select any key, Key 1 is selected, as it is default key.
Then click on Write and it will update the registry and driver.
Another WEP key generation method is by inserting the Key values directly from the keyboard. And
click on the Write to update driver and registry. Select the Key number and use that Key for accessing
the Access Point. If the Key is not entered correctly, a client cannot access the resources. This Key
value protects the illegal access to the wireless network resources. As the wireless channel is more
prone to the illegal access, WEP provides the users safe access.
