INTRODUCTION
The 22Mbps Wireless Network PCI Adapter
delivers enhanced IEEE 802.11b high performance
for up to 22Mbps, which is double of that offered
by most of the current wireless products in the
market.
The 22Mbps high data rate is made possible by the
latest advanced TI wireless technology, which incorporates the new PBCC modulation
method. Unlike the ordinary CCK modulation, not only the new PBCC modulation
method offers double data rate for up to 22Mbps, but also it gives 20% more distance
coverage.
The 22Mbps Wireless Network PCI Adapter is fully compatible with other 11Mbps
wireless de vices. The simple step-by-step installation allows you to have the wireless
network setup in no time. The comprehensive configuration utility makes the setting
controlfor the PCI Adapter easier than ever.
The 22Mbps Wireless Network PCI Adapter is an ideal wireless device that truly
makes the idea of “wireless”come true. Please take a moment to read through this
manual and get acquaintedwith this cutting-edge product.

GETTING STARTED
Getting To Know The 22Mbps Wireless Network PCIAdapter
WIRELESS NETWORK PCI Adapter’s LEDs
ØPower LED
ON when the unit is powered up
Blink indicates wireless activity
Setting Up The Wireless Network
There two wireless network topologies that you can setup your wireless card with.
One is called “Ad-Hoc”, and the other is “Infrastructure”. On an Ad-Hoc network,
two or more computers each has at least one wireless network client device such as
wireless PCI Adapter installed, establish point-to-point data communication with each
other. While on an Infrastructure network, everywireless station communicates
through Access Points.
Setting Up Ad-Hoc Network
The idea of Ad-Hoc Network is rather simple. All the wireless station are set to use the

7
same BSS ID and channel to establish communication linkage with each other to form
a point-to-point network for data transmissionand reception.
Setting Up Infrastructure Network
In order to setup an Infrastructure of a wireless network such as the example shown
above, you will need the following:
1. A broadband Internet connection.
2. ADSL or Cable modem provided by your ISP as part of the broadband connection
installation.
3. A Router that connects to the ADSL/Cable modem for internet connection sharing.
4. An Access Point to connect with the Router to form a wireless infrastructure
network.
5. Wireless clients equippedwith wireless networking devices such as wireless PC
Card for wireless connection.
In this case,all the wireless clients and Access Point operate under the same channel
with the same ESSID. The wireless clients are all connected to the Access Point for
data transmission.

CONFIGURING YOUR WIRELESS PCI Adapter
Link Info. Page
This is the default page when the utility starts up.
Status: Shows the BSSID associated, which can be used to identify the wireless
network.
SSID:Shows current SSID, which must be the same for the wireless client and AP in
order for communication to be established.
TxRate:Shows the current data rate used for transmitting.
Channel: Shows the current channel for communication.
Radio Off button: When clicked, you disable the radio signal, and cut-off the wireless
connection.
Link Quality: Shows the link quality of the 22Mbps wireless Network PCI Adapter
with the Access Point when operating under Infrastructure mode.
Signal Strength: Shows the wireless signal strength of the connection between the
22mpbs wireless Network PCI Adapter withthe Access Point.
Data Rate: Shows the statistics of data transfer, and the calculation is based on the
number of packets transmitted and received.

14
Configuration Page
This is the page where you can change the basic settings of the Access Point with the
minimum amount of effort to adjust a secure wireless network.
SSID: Service Set Identifier, which is a unique name shared among all clients and
nodes in a wireless network. The SSID must be identical for each clients and nodes in
the wireless network.
BSS Type: There are two types available for selection
lInfrastructure –to establish wireless communication with LAN and other
wireless clients through the use the Access Points.
lAd-Hoc –to establish point-to-point wireless communication directly with
other wireless client devices such as wireless network PCI Adapter.
Channel: The value of channel that AP will operate in. You can select the channel
range of 1 to 11 for North America (FCC) domain, 1 to 13 for European (ETSI) domain
and 1 to 14 for Japanese domain.
Tx Rate:Select the data rate for data transmission.
Preamble:Select Long or Short Preamble type. Preamble is a sequence of bits
transmitted at 1Mbps that allows the PHY circuitry to reach steady-state demodulation
and synchronization of bit clock and frame start. Two different preambles and headers
are defined: the mandatory supported Long Preamble and header, which interoperates
with the 1 Mbit/s and 2 Mbit/s DSSS specification (as described in IEEE Std 802.11),
and an optional Short Preamble and header (as described in IEEE Std 802.11b). At the
receiver, the Preamble and header are processed to aid in demodulation and delivery of

15
the PSDU. The Short Preamble and header may be used to minimize overhead and,
thus, maximize the network data throughput. However, the Short Preamble is
supported only from the IEEE 802.11b (High-Rate) standard and not from the original
IEEE 802.11. That means that stations using Short-Preamble cannot communicate with
stations implementing the original version of the protocol.
Power Mode: There are 3 modes to choose from
lContinuous Access Mode (default) –the PCI Adapter is constantly operating
with full power and it consumes the most power
lMaximum Power Save –the PCI Adapter consumes the least power and only
operates when there is wireless network activity.
lPower Save –the PCI Adapter consumes the moderate level of power.
4X Config.: When “4X enable” is selected, you will be running 22Mbps PBCC+4X
mode, the wireless transmission speed can achieve over 12Mbps real throughput
assuming that the other wireless LAN devices are also running 22Mbps PBCC+4X.
Note!: 4X mode is proprietary transmission mode available only with our solution
chipset. In order to achieve superb speed by 4X or 22Mbps PBCC mode, both the
transmittingand receiving parties must be using our WLAN solution products.
For the changes made to any of the items above to be effective, click “Apply”. The
screen will be changed back to Link Info. Page

16
Security Page
This is the page where you configure Security settings of your 22Mbps wireless PCI
Adapter.
Data Encryption: Click the box to enable Data Encryption feature.
Aut. Mode: There are three modes available to choose from.
lOpen Authentication –the sender and receiver do not share secret Key for
communication. Instead, each party generates its own key-pairs and ask the
other party to accept it. The key is regenerated when the connection is
established every time.
lShared Authentication –the senderand receiver shares the common key
for data communication, and the key is used for extended length of time.
lAuto –depend on the communication to establish, and automatically use the
proper authentication mode.
The following will only be activated to allow for configuration when Data Encryption
is enabled.
Default Key: select one of the 4 keys to use.
Network Key: enter values to these fields, either in HEX or ASCII formats. You only
have to enter the key that you will use
Key Length: select 64, 128 or 256 bits as the length of the keys
Key Format: ASCIIor HEX(Please refer to Appendix G: Glossary for details about
these two formats).

17
SiteSurvey Page
This page allows to utilize the SiteSurvey function to scan for the available wireless
network (wireless clients and Access Points) and select one to establish wireless
communication.
Available Network –displays the wireless networks (wireless clients and Access
Points) that are in your signal range. Select any one of them and establish
communication by simply mouse double-click or a single click on the “Connect”
button.
Click “Refresh”button to start scanning for available networkagain.
Profile –You can create and manage the created profiles for Home, offices or
public areas.
By double-clicking on one of the created profile, the setting will adapt to the
configuration such as SSID, channel, and WEP settings saved by that particular
profile.
Click to select any one of the profiles, and you can
Click on “Remove”button to remove the profile, or
Click on “Properties”button to view and change its settings. The Properties is
very similar to that of adding profile.
Click “Add”to add a profile, and the following screen would appear.
