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 PC Card installed, establish point-to-point data communication with each
other. While on an Infrastructure network, every wireless 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
same BSS ID and channel to establish communication linkage with each other to form
a point-to-point network for data transmission and reception.
6
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 equipped with 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.

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 PC Card with the Access
Point when operating under Infrastructure mode.
Signal Strength: Shows the wireless signal strength of the connection between the
22mpbs wireless PC Card with the Access Point.
Data Rate: Shows the statistics of data transfer, and the calculation is based on the
number of packets transmitted and received.
13
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
z Infrastructure – to establish wireless communication with LAN and other
wireless clients through the use the Access Points.
z Ad-Hoc – to establish point-to-point wireless communication directly with
other wireless client devices such as wireless network PC Card.
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
14
receiver, the Preamble and header are processed to aid in demodulation and delivery of
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
z Continuous Access Mode (default) – the PC Card is constantly operating
with full power and it consumes the most power
z Maximum Power Save – the PC Card consumes the least power and only
operates when there is wireless network activity.
z Power Save – the PC Card 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
transmitting and 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

Security Page
This is the page where you configure Security settings of your 22Mbps wireless PC
Card.
Data Encryption: Click the box to enable Data Encryption feature.
Aut. Mode: There are three modes available to choose from.
z Open 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.
z Shared Authentication – the sender and receiver shares the common key
for data communication, and the key is used for extended length of time.
z Auto – 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.

2. What is the difference between 22Mbps and 11Mbps wireless products?
What’s the benefit of 22Mbps Wireless Access Point?
The 22Mbps is made possible by the new modulation method called PBCC
developed by TI, which is different from the current CCK modulation method for
11Mbps. The 22Mbps Wireless Access Point offers double data rate than that of
11Mbps with 20% more distance coverage. The 22Mbps wireless products also
operate in the 2.4GHz ISM band and they are backward compatible with 11Mbps
wireless products.
3. What is Roaming?
Roaming is the ability of portable computers, e.g., Packet PC and notebook, to
have consistent and continuous data transmission/reception throughout an area
covered by more than one Wireless Access Point. In order to achieve seamless
connectivity, all the wireless clients and Access Points must be set to use the same
SSID. When a user walked out of the coverage area of one AP into another, the
wireless client network device will automatically reestablish connection with the
new AP.
4. What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the
manufacturer to any Ethernet networking devices, e.g. a network adapter, that
allows the network to identify it at the hardware level. Unlike IP addresses,
which can be changed or dynamically assigned by the network, the MAC address
of a networking device is permanent.
5. What is WEP?
Wired Equivalent Privacy (WEP) is a type of data encryption mechanism
described in the IEEE 802.11 standard. The 22Mbps Wireless Access Point
supports 64/128/256 bit shared key for WEP.
6. Would the information be transmitted securely in the air?
WLAN offers two layers of protection for security. First layer is on the hardware
level. As with Direct Sequence Spread Spectrum (DSSS) technology, it has the
inherent security feature of scrambling. Second of all, on the software level, the
security control is made possible by Wired Equivalent Privacy (WEP) for access
control.
7. What is ISM band?
23
The FCC and their counterparts outside of the U.S. have set aside bandwidth for
unlicensed use in the ISM (Industrial, Scientific and Medical) band. The 2.4GHz
unlicensed ISM band is available worldwide, which presents the opportunity for
the global market of 802.11b high speed wireless products.
8. What is 4X mode?
This is a proprietary wireless data transmission mode provided by TI, which
enhances TI’s 22Mbps PBCC speed to reach data throughput to over 12Mbps.
Since it is not IEEE 802.11b standard wireless data mode, in order to allow 4X
mode, both the receiving and transmitting parties must be using TI solution.
