2 Wireless LAN Application
Wireless LAN (Local Area Network) systems offer a great number of advantages over a
traditional, wired system. And these systems support the same network configuration options
of the legacy Ethernet LANs as defined by IEEE 802 standard committee. Besides, they are
more flexibles, easier to setup and manage and often more cost effective than wired
equivalence. In general, wireless LAN products can be configured as “Ad-Hoc (Peer-toPeer)” for departmental or SOHO LANs or “Infrastructure (Access Point)” for enterprise
LANs.
2-1 Ad-Hoc Topology
This is the peer-to-peer mode of operation without access point. An Ad-Hoc wireless LAN is a
group of computers, each equipped with one wireless adapter, connected as an independent
wireless LAN. Computers in a specific Ad-Hoc wireless LAN must be configured at the same
radio channel and the same SSID for establishing the wireless connection. Ad-Hoc wireless
LAN is applicable at a departmental scale for a branch or SOHO operation.

Infrastructure Topology
WM1 Mini-PCI User Manual
This mode of operation requires the presence of an access point at least. In this mode, all
wireless LAN client devices need to communicate with the access point and then access to a
wired LAN such as Ethernet via the access point. Therefore, an integrated wireless and wired
LAN is called an infrastructure configuration. A group of wireless LAN client users and an
access point construct a Basic Service Set (BSS). Each wireless LAN client devices in this
BSS can talk to any devices in the wired LAN infrastructure via the access point. In this
infrastructure configuration, wireless LAN systems will extend the accessibility to the wired
LAN. On the other hand, infrastructure mode also supports roaming capabilities for mobile
wireless LAN users. More than one BSS can be configured as an Extended Service Set (ESS).
The continuous network allow wireless LAN users to roam freely within an ESS. All wireless
LAN client devices and access points within the ESS must be configured with the same ESS
ID and use the same radio channel.

_______
WM1 Mini-PCI User Manual
Profile Name
The name of the profile currently in use.
Basic
SSID
The name of the SSID (Service Set Identification) associated with the profile
State
This field is used to display the current state of the driver. When the state “associated” means
normal flow of operation in access point or peer-to-peer devices. During access point
connection, it will represent the MAC address of the access point. And during an Ad-Hoc
connection, it will read the MAC address of the peer-to-peer devices. A state of “scanning”
means that the node is searching for available access point and can not detect any wireless
device within range.
Mode
It will be shown the access point or peer-to-peer in this field.
Access point – This mode of operation requires the presence of an 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.
Peer-to-peer – This is the peer-to-peer mode of operation. All communication is done from
client to client without the use of an access point.
Current Tx Rate
It will shown the transmit rate is being currently used for an active connection. This value has
no meaning when state is “scanning”
Current Channel
Channel being used, if any, for this wireless connection. It will shown the communication
channel ranging from 1 to 11.
Power Saving Mode
Indicates of power saving mode is enable or disable. Power saving mode reduced energy
usage by temporarily disconnecting wireless connections when the connection is idle.
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.
Advance
RTS Threshold
Indicated of RTS threshold is disable or the value ranging from 0 to 2432.
Frag Threshold
Indicated of frag threshold is disable or the value ranging from 256 to 2432.
Beacon Interval
Indicated of beacon interval is disable or the ranging from 20 to 1000.

Name given to the profile. Any user can add 10 maximum different profiles if he wish.
Defaults
Pressing this button restores each field in the panel to its default value. The default value for
each field as below.
Basic
SSID
The name of the SSID (Service Set Identification) associated with the profile. The default
value is “ANY”, This allows your wireless client to automatically associate to any access
point in the vicinity of your wireless client.
Mode
This field allows you to select from a list of supported network mode. The modes displayed
will have “Access Point” and “Peer-to-Peer. The default value is “Access Point”.
Current Tx Rate
The transmission rate at which the data packets are transmitted by client of access point. You
can set this to 1Mbps, 2Mbps, Auto 1 or 2Mbps, 5.5Mbps, 11Mbps, Fully Automatic. The
default value is “Fully Automatic”.
Peer-to-Peer Channel
Changing the channel is only effective in Ad-Hoc networks. Networking operating
infrastructure mode automatically scan for a channel. Be aware that when the peer-to-peer
mode is selected, be sure to set your wireless stations with the same channel.
Power Saving Mode
The field allows you to set enable or disable. Power saving mode reduced energy usage by
temporarily disconnecting wireless connections when the connection is idle. The default value
is “Disable”.
Advance
RTS Threshold
The field allows you to set enable or disable. When the field is enable, you can set the value
ranging from 0 to 2432. RTS threshold is a mechanism implemented to prevent the “Hidden
Node” problem. “Hidden Node” is a situation in which two stations are within range of the
same access point, but are not within range of each other. Thus, it provides a solution to
prevent data collisions. Enabling RTS Threshold may cause redundant network overhead that
could negatively affect the throughput performance.
Frag Threshold
The field allows you to set enable or disable. When the field is enable, you can set the value
ranging from 256 to 2432. Fragmentation mechanism is used for improving the efficiency
when high traffic flows along in the wireless network. If your wireless devices often transmit
large files in wireless network, you can enable the Fragmentation Threshold and the
mechanism will split the packet.

Changing the Beacon Interval is only effective in peer-to-peer mode. You can set the value
ranging from 20 to 1000.
Encryption Tab
The
Encryption
tab is used to desire an additional measure of security on your wireless
network, which can be achieved by using WEP (Wired Equivalent Privacy) encryption. To
prevent unauthorized wireless stations from accessing data transmitted over the network,
WEP can support high secure data 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. The
Encryption
tab contains some fields as below.
Encryption [WEP security]
WEP Key – Create Key Manually, Create Keys with Pass-phrase
Key1, Key2, Key3, Key4

Encryption [WEP security]
The field allows you to set Disabled, 64-bit, 128-bit. When setting 64bit, or 128 bits, it means

WEP security is used.
WEP Key
You can use “Create Key Manually” or “Create Keys with Pass-phrase” method to enter
encryption keys. It 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 correct digits and letters. The detailed descriptions will be shown as below for
these two kinds of methods:
Create Key Manually
For 40-bits encryption:
- Five alphanumeric characters in the range of “a-z”, “A-Z” and “0-9”. (e.g. MyKey)
- 10 digit hexadecimal values in the range of “A-F” and “0-9”. (e.g. 11AA22BB33).
For 128-bits encryption:
- 13 alphanumeric characters in the range of “a-z”, “A-Z” and “0-9”. (e.g. WEPencryption).
- 26 digit hexadecimal values in the range of “A-F” and “0-9”. (e.g.
11AA22BB33123456789ABCDEFF)
.
Create Keys with Pass-phrase
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.
Key1, Key2, Key3, Key4
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 product. These fields also display the keys when
they are generated using a Pass-phrase.
Use WEP key
This field updates the driver with the four keys displayed in Key1 through Key4. These keys
are also written to the registry for permanent storage. For 128 bit encryption, this field will be
invisible.
