Wireless Solutions and Application
Access existed networks for mobile workers
Allow doctors, nurses, sales access their database while keeping mob ility in the
hospitals, retail stores, office campus or other buildings.
Difficult-to-wire environment
There are many situations where wires cannot or cannot easily be laid. Historic
buildings, older buildings, open areas and across busy streets make the installation
of LANs either impossible or very expensive.
Frequently changed environment
Show rooms, meeting rooms, retail stores, and manufacturing sites where the
workplace located are frequently rearranged.
Wired LAN backup
Network managers implement wireless LANs to provide backup for
mission-critical applications running on wired networks.
Wireless extensions to wired networks
Network managers in dynamic environments can minimize the overhead caused
by moves, extensions to networks, and other changes with wireless LANs.
Temporary workgroup
Trade shows, exhibitions, and construction sites that require a temporary network.
Retailers, airlines, and shipping companies need additional workstations during
peak periods.
Small Office/ Home Office (SOHO) Network s
SOHO users need a cost-effective, easy and quick installation of a small network.

This Wireless Compact Flash Adapter is a “ready-to-use” device. The default
settings have finished for a typical Infrastructure Wireless LAN. After installing
the Setup Utility and the Driver into the handheld devices, simply install the Wireless
LAN Compact Flash Card onto your handheld devices and it is ready to use. In some
situations, however, you may want to adjust the configuration settings to manage
your wireless network. The Wireless LAN Utilit y of this Compact Flash Card
provides you to make the configuration changes by an easily interface. If you need to
adjust the settings, please following the instructions below.

Status
State
This item s hows status information about the radio link as shown in Figure 15.
Ÿ Associated BSSID – means the wireless client is
connected to an access point. BSSID is shown
in the form of six hex digits which is the MAC
address of the access point.
Ÿ Scanning – means the wireless client is
searching for an available acce ss point in
infrastructure mode.
Ÿ Disconnected – means there are no access
points or other wireless clients (if
communicating in Ad -hoc mode), or the PC
Card is unplugged in your computer.
Current Tx Rate (Mbits/s)
The data speed that wireless client is
transmitting.
Current Channel
The operation radio frequency channel that wireless client is using in
infrastructure mode. In infrastructure mode, wireless client will always go the
Figure 15
same channel as their Access Point.
Throughput (Bytes/sec)
Tx: shows the outgoing (sent) data speed.
Rx: shows the incoming (received) data speed.
13
Link Quality
In infrastructure mode, this bar displays the transmission quality between a
WLAN station (Access Point) and Wireless LAN PC Card. In Peer-to-Peer mode
(Ad-Hoc), this bar displays the link quality between two Wireless LAN PC Cards.
Signal Strength
This bar displays the signal strength level. The higher bar is, the more powerful
radio signal is received by the PC Card.
Disable/Enable Radio
This button is used like a switch that allows users to turn off the wireless radio by
clicking this button and turn it on again.
Rescan
The radio will rescan all available channels by pressing this button. You can push
this button to rescan the channels for better link quality when the link quality is
poor.
Configuration
Make configuration changes by specifying the proper configuration
parameters on this configuration tab as shown in Figure 16.
Profile
You can give a name for this field to a setting of
configuration parameters, such as Network
Name, Network Type, Transmit Rate,
Encryption (WEP Security), etc. It makes much
easier for users to change WLAN configuration
settings who need to switch working places
frequently. Suppose that a user has to work
between the two different offices where there
are different network settings. In this case, this
user just needs to setup two profiles for the two
offices and simply selects the proper profile
when the user switches to the different office.
Figure 16
Network Name
For infrastructure mode, you need to type in the SSID of the access point to which
your computer connects. For Ad-Hoc (peer-to-peer) mode, you need to type in the
virtual SSID of the Ad-Hoc network to which your computer attaches.
Network Type
There are two types of netwo rk modes in this drop-down list, Peer-to-Peer and
Access Point (Infrastructure).
14
Ÿ Peer to Peer: If two or more stations exchange data directly without an access
point, you need to select Peer-to-Peer mode. Each station in a Peer-to-Peer
(Ad-Hoc) network must specify the same network name (SSID) and
peer-to-peer channel.
Ÿ Access Point: If at least one access point involves in the communications in a
group of stations, you need to select Infrastructure mode. Each station needs to
specify the same network name (SSID) as the access point.
Peer-to-Peer Channel
This option is just for Peer-to-Peer (Ad-Hoc) mode. You need to specify a
channel on which the communications are established. Each station in a
Peer-to-Peer (Ad-Hoc) network must specify the same channel and network type
(SSID).
Power Save Mode
Power Save function as shown in Table 1 .This function can conserve more
battery energy and extend the battery life. This function has three options for
power save mode. Below is detailed description.
On: Enable Power Save function.
Off: Disable Power Save function.
Auto: Utility will automatically detect what kind of
power supply a machine uses and then determine
to enable or disable Power Save function.
If device uses battery, Power Save Mode is set to
on.
If device uses AC Power , Power Save Mode is
set to off.
Table 1
Transmit Rate
The transmission rate on which the data packets are transmitted by the client can
be specified in this drop-down list as shown in Table 2. Below are the available
transmission rates.
Full Automatic PC Card chooses the highest
available transmission rate
11 Mbps allows only 11 Mbps operation
5.5 Mbps allows only 5.5 Mbps operation
Auto 1 or 2 Mbp allows only 1 or 2 Mbps operation

Defaults
Data
Once this button is pressed, all the settings will be set back to the default settings.
Encryption
Encryption is designed to make the data transmission more secure. you can
select 64 or 128-bit WEP (Wired Equivalent Privacy) key to encrypt data (Default
setting is Disable). WEP encrypts each frame tra nsmitted from the radio using one of
the Keys from this panel. When you use WEP to communicate with the other wireless
clients, all the wireless devices in this network must have the same encryption key or
passphrase.
Encryption (WEP)
Choose one of the encryption key (64 bit or
128bit) from the Encryption (WEP
Security) drop-down list to create
encryption key. Click either on Create Keys
Manually radio button or on Create Keys
with Passphrase radio button. There are
two ways, Alphanumeric and
Hexadecimal, to set the different characters
as shown in Table 3.
Create Keys Manually: Alphanumeric
Type 5/13 alphanumeric characters in the
key field
Create Keys Manually: Hexadecimal
Type a 10/26 hexadecimal numbers (1-9;
A-F) in the key field

Use WEP Key
This drop-down list allows you to specify which of the four encryption keys that
you want to use.

Network Topology
To better understand how the wireless LAN products work together to create a
wireless network, it might be helpful to depict a few of the possible wireless LAN
USB Adapter network configurations. The wireless LAN products can be configured
as:
1. Ad-hoc (or peer-to-peer) for departmental or SOHO LANs.
2. Infrastructure for enterprise LANs.
3. IP Sharing for 56K/ISDN TA/Cable/DSL Modem – Connect Internet and your
SOHO network.

An Ad -Hoc wireless LAN is a group of computers as well as PDAs that are equipped
with a wireless adapter, connected as an independent wireless LAN (Local Area
Network).
NOTE: Must configure all wireless devices in the same Radio Channel, SSID and

All of the Senao’s wireless devices provide access to a wired LAN through the
wireless extension of the local network. An integrated wireless and wired LAN by
using the Access Points is called an Infrastructure configuration.
Infrastructure configuration allowed users extend the accessibility of the wireless
and wired LAN. Multiple 802.11b Access Points will allow roaming and will increase
the effective transmission range.

The mobile client will connect to any 802.11b AP that is within range. Each
802.11b Access Point within a roaming network must have a unique Channel and the
same SSID and Encryption Keys (if WEP is enabled). 802.11b products can use
three non-overlapping Channels within the same vicinity (Channels 1, 6, and 11 are
non-overlapping). Users can move between the 802.11b Access Points in the network
freely.
