3. 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 peerto-peer networks suitable for a small number of users to full infrastructure networks of thousands
of users that allows roaming over a broad area.
4. Installation for Windows platform

5. Configuration Utility
After the installation of the PRISM WLAN Configuration Utility, its icon appears in the System Tray in
the bottom right corner of your desktop.
The color behind the Intersil logo indicates the link status.
Red indicates no or very poor link quality.
Yellow indicates a usable but weak link.
Green indicates a good or excellent link.
You can also view the status of the link by placing the cursor over the Configuration Utility icon, as
shown in the following illustration. This illustration indicates that the PRISM WLAN Card is able to
communicate, but that the signal to the radio is weak.
The Configuration menu lets you specify the operating parameters for your PRISM WLAN Interface card. When
you first start the Configuration Utility, this menu is displayed. If another menu is displayed, you can display the
Configuration options by clicking on its tab in the Configuration Utility panel.
18
5.1 Configuration Tab
The Configuration menu lets you specify the operating parameters for your PRISM WLAN Interface
card. When you first start the Configuration Utility, this menu is displayed. If another menu is
displayed, you can display the Configuration options by clicking on its tab in the Configuration Utility
panel.
Setting the Profile
A profile is a named set of operating parameters for your PRISM WLAN Interface card. The Profile
field lets you set values for all parameters by selecting a previously defined profile. Click the down
arrow at the right of the Profile field to display the available profiles for your PRISM WLAN Interface
card.
You will always have at least one profile, named Default. Initially, this profile contains the parameters
configured at installation. You can modify this profile at any time after the installation. After changing
parameters, you can save them in the profile named in this field by clicking the Apply button in the
Configuration Utility panel.
You can also create additional profiles by typing a name in the Profile field. When you change the
name in the Profile field and then click the Apply button, the Configuration Utility uses the current
parameters for your card to create a separate profile. You can then switch between profiles by clicking
the down arrow at the right of the Profile field, selecting a profile from the drop-down list, and clicking
the Apply button.
The following example describes a situation in which you would want to create multiple profiles.
Suppose that you use the wireless LAN at your work, but you also have a network in your home (with
a wireless Access Point) for sharing an internet connection and a printer between several computers.
Suppose also that you have another office within your business which also has WLAN capability, but
which is configured differently than your main office.
In this situation, you can create a different profile for each of these three environments. Each profile
specifies the parameters used on a single network. Moving from one location to another, you only
need to apply the appropriate profile to be able to participate in the local network.
19
Setting the Mode
The PRISM WLAN Interface card can operate in one of two modes, which are specified in the Mode
field of the Configuration menu. Clicking the down arrow at the right of the Mode field displays the
available modes.
802.11 AdHoc Mode
IEEE 802.11, the standard on which the WLAN protocol is based, defines two modes to handle two
separate needs. The first, called AdHoc (or IBSS) mode, is used when two or more wirelesslyenabled PCs wish to exchange data directly, without an Access Point. In this case the PCs can
establish an AdHoc network in which they are the only members and over which they can exchange
data. To exchange data, each computer participating in the AdHoc network must also specify the
same SSID and AdHoc Channel in this menu.
Infrastructure Mode
The second mode defined by the IEEE 802.11 standard is called infrastructure mode, and is the
primary application for WLAN operation. In this mode all data on the wireless network is directed to an
Access Point, which then routes the data to the appropriate wireless station. The Access Point may
also be configured to allow data to be bridged from the wireless network to wired networks.
To participate in a wireless LAN in infrastructure mode, every station and Access Point must specify
the same SSID. In infrastructure mode, all available channels are scanned for traffic, so there is no
need to specify a channel.
Setting the SSID
The SSID is the Service Set IDentifier used by Access Points and stations to identify a wireless LAN.
Your PRISM WLAN Interface card scans the available channels looking for an Access Point (in
infrastructure mode) or another station (in AdHoc mode) which has specified this same SSID. It then
attempts to associate with these Access Points or stations to form a wireless LAN.
To change the SSID, simply highlight it, type the new SSID, and click the Apply button.
In typical infrastructure applications a company will use a single SSID for all Access Points. If the
radio is scanning and cannot find a channel when an Access Point is known to be in range, verify that
the SSID is set correctly.
20
Setting the Transmit Rate
The Transmit Rate field specifies the rate at which the radio in your PRISM WLAN Interface card
transmits and receives data. You can view the available rates by clicking the down arrow at the right
of the Transmit Rate field.
The transmit rate can be set to:
•= Fully Automatic – your PRISM card chooses the highest available rate providing reliable
communications based on the capabilities of the Access Point or station with which it communicates
and on the received signal quality
•= Auto 1 or 2 Mb – allows only 1 and 2 Mb/s operation
•= 5.5 Mb – allows only 5.5 Mb/s operation
•= 11 Mb – allows only 11Mb/s operation
To change the Transmit Rate, click the down arrow at the right of the field, highlight the rate you want
to set, and click the Apply button.
Under most conditions, you should choose Fully Automatic as the transmit rate. In general, fixed rates
are used only in test environments.
Enabling Power Save Mode
The IEEE 802.11 standard provides a Power Save Mode. In this mode your PRISM card listens for a
beacon (a periodic frame which defines the network type and attributes) and determines the beacon
interval. Between beacons the card puts itself to sleep, enabling power savings. At the time of the
expected beacon the card wakes itself up and receives the beacon. The received beacon contains
information about whether the Access Point or station has buffered frames for the card. If frames are
available the card requests those frames until no more frames are available. The card then goes back
to sleep until the next beacon.
For Access Points that support power save mode and for stations equipped with WLAN cards,
enabling this mode can significantly reduce power consumption, which is particularly important if the
host computer is operating on battery power. However, be aware that power save mode also results
in lowered transmission and reception speed on the wireless LAN.
21
Selecting the Ad Hoc Channel
When communicating in AdHoc or Pseudo AdHoc mode, you must specify a channel on which
communications will take place. To specify a channel, click the up or down arrow at the right of the
AdHoc Channel field until the channel you want to set appears, and then click the Apply button.
This field is greyed in infrastructure mode because the channel is automatically selected by the
Access Point.
Encrption
The Encryption menu lets you enable encryption and set the encryption keys. To see the available
encryption methods, click the down arrow at the right of the Encryption {WEP} field.
There are two encryption methods available. The IEEE 802.11 specification defines Wired Equivalent
Privacy (WEP) using a 64-bit key. This capability was extended by the industry to allow a 128 bit key.
If you specify an encryption method, you will only be able to communicate with Access Points and
stations that use the same encryption method and keys.
22
Disabling Encryption
To disable encryption, click the down arrow at the right of the Encryption field, select Disabled, and
click the Apply button.
Enabling Encryption
To enable encryption, click the down arrow at the right of the Encryption field, select either 64 bit or 128
bit, and click the Apply button. After enabling an encryption method, you must then specify encryption
keys, as described in the following sections.
Creating Encryption Keys Using a Passphrase
To create encryption keys using a passphrase, click the radio button next to Create Key with Passphrase
and type a character string in the Passphrase field. As you type, the Configuration Utility uses an
algorithm to generate four keys used for encryption.
When you finish typing your character string and click the Apply button, the Configuration Utility uses
asterisks to mask both your passphrase and the keys it generates.
Using a passphrase to generate the four keys makes it easy to set the same keys for all members of
your wireless LAN.
23
Creating Encryption Keys Manually
If you want, you can create encryption keys manually by clicking the radio button next to Create Key
Manually, as shown in the following illustration.
When you click this button, the cursor appears in the field for Key 1. For 64-bit encryption, you must
type exactly 10 hexadecimal digits in each of the four key fields; for 128-bit encryption, you must type
exactly 26 hexadecimal digits. You then click the Apply button to create your encryption keys. After
you click the Apply button, the Configuration Utility uses asterisks to mask your keys.
Default Key
The Default Key field lets you specify which of the four encryption keys you use to transmit data on
your wireless LAN. You can change the default key by clicking on the down arrow at the right of this
field, selecting the number of the key you want to use, and then clicking the Apply button. As long as
the Access Point or station with which you are communicating has the same key in the same position,
you can use any of the keys as the default.
24
Link Tab
The Link menu provides information on the status of your communications with the wireless LAN.
The fields in this menu provide the following information:
•= State: shows the association state of your computer with the wireless LAN. When operating in
Infrastructure mode, this field shows the MAC address of the Access Point with which you are
communicating. When operating in AdHoc mode, this field shows the virtual MAC address used by
computers participating in the AdHoc network.
•= Current Channel: shows the channel on which the connection is made. In Infrastructure mode, this
number changes as the radio scans the available channels.
•= Current Tx Rate: shows the highest transmit rate of the current association.
•= Throughput: shows the short term transmit and receive throughput in bytes/second, and is
continuously updated.
•= Link Quality: is based on the quality of the received signal of the Access Point beacon.
•= Signal Strength: is based on the received signal strength measurement of the baseband processor of
the Beacon signal.
You can click the Rescan button to force the radio to rescan all available channels. If your link quality
or signal strength is poor, rescanning can be used to push the radio off a weak Access Point and
search for a better link with another Access Point.
25
About Tab
The About menu provides information on the version of the Network Driver, the Configuration Utility,
and the firmware in the PRISM WLAN Interface card. In addition, this menu also provides the MAC
address of the PRISM card.
