73. Wireless LAN BasicsWireless 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 morecost effective than their wired equivalence.Using radio frequency (RF) technology, WLANs transmit and receive data over the air, minimizing theneed for wired connections. Thus, WLANs combine data connectivity with user mobility, and, throughsimplified configuration, enable movable LANs.With wireless LANs, users can access shared information without looking for a place to plug in andnetwork managers can set up or augment networks without installing or moving wires. Wireless LANsoffer the following productivity, convenience and cost advantages over traditional wired networks:• Mobility - Wireless LAN systems can provide LAN users with access to real-time informationanywhere in their organization. This mobility supports productivity and service opportunities notpossible with wired networks. • Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and caneliminate 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 hardwaremight be higher than the cost of wired LAN hardware, overall installation expenses and life-cyclecosts will be significantly lower. Long-term cost benefits are greatest in dynamic environmentsrequiring frequent moves, adds, and changes. • Scalability - Wireless LAN systems can be configured in a variety of topologies to meet the needsof specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to full infrastructure networks of thousandsof users that allows roaming over a broad area.

185. Configuration Utility After the installation of the PRISM WLAN Configuration Utility, its icon appears in the System Tray inthe 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, asshown in the following illustration. This illustration indicates that the PRISM WLAN Card is able tocommunicate, but that the signal to the radio is weak.The Configuration menu lets you specify the operating parameters for your PRISM WLAN Interface card. Whenyou first start the Configuration Utility, this menu is displayed. If another menu is displayed, you can display theConfiguration options by clicking on its tab in the Configuration Utility panel.
195.1 Configuration TabThe Configuration menu lets you specify the operating parameters for your PRISM WLAN Interfacecard. When you first start the Configuration Utility, this menu is displayed. If another menu isdisplayed, you can display the Configuration options by clicking on its tab in the Configuration Utilitypanel.Setting the ProfileA profile is a named set of operating parameters for your PRISM WLAN Interface card. The Profilefield lets you set values for all parameters by selecting a previously defined profile. Click the downarrow at the right of the Profile field to display the available profiles for your PRISM WLAN Interfacecard.You will always have at least one profile, named Default. Initially, this profile contains the parametersconfigured at installation. You can modify this profile at any time after the installation. After changingparameters, you can save them in the profile named in this field by clicking the Apply button in theConfiguration Utility panel.You can also create additional profiles by typing a name in the Profile field. When you change thename in the Profile field and then click the Apply button, the Configuration Utility uses the currentparameters for your card to create a separate profile. You can then switch between profiles by clickingthe down arrow at the right of the Profile field, selecting a profile from the drop-down list, and clickingthe 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 (witha 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, butwhich is configured differently than your main office.In this situation, you can create a different profile for each of these three environments. Each profilespecifies the parameters used on a single network. Moving from one location to another, you onlyneed to apply the appropriate profile to be able to participate in the local network.
20Setting the ModeThe PRISM WLAN Interface card can operate in one of two modes, which are specified in the Modefield of the Configuration menu. Clicking the down arrow at the right of the Mode field displays theavailable modes. 802.11 AdHoc ModeIEEE 802.11, the standard on which the WLAN protocol is based, defines two modes to handle twoseparate needs. The first, called AdHoc (or IBSS) mode, is used when two or more wirelessly-enabled PCs wish to exchange data directly, without an Access Point. In this case the PCs canestablish an AdHoc network in which they are the only members and over which they can exchangedata. To exchange data, each computer participating in the AdHoc network must also specify thesame SSID and AdHoc Channel in this menu.Infrastructure ModeThe second mode defined by the IEEE 802.11 standard is called infrastructure mode, and is theprimary application for WLAN operation. In this mode all data on the wireless network is directed to anAccess Point, which then routes the data to the appropriate wireless station. The Access Point mayalso 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 specifythe same SSID. In infrastructure mode, all available channels are scanned for traffic, so there is noneed to specify a channel.Setting the SSIDThe 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 (ininfrastructure mode) or another station (in AdHoc mode) which has specified this same SSID. It thenattempts 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 theradio is scanning and cannot find a channel when an Access Point is known to be in range, verify thatthe SSID is set correctly.
21Setting the Transmit RateThe Transmit Rate field specifies the rate at which the radio in your PRISM WLAN Interface cardtransmits and receives data. You can view the available rates by clicking the down arrow at the rightof the Transmit Rate field.The transmit rate can be set to:• Fully Automatic – your PRISM card chooses the highest available rate providing reliablecommunications based on the capabilities of the Access Point or station with which it communicatesand 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 operationTo change the Transmit Rate, click the down arrow at the right of the field, highlight the rate you wantto set, and click the Apply button.Under most conditions, you should choose Fully Automatic as the transmit rate. In general, fixed ratesare used only in test environments.Enabling Power Save ModeThe IEEE 802.11 standard provides a Power Save Mode. In this mode your PRISM card listens for abeacon (a periodic frame which defines the network type and attributes) and determines the beaconinterval. Between beacons the card puts itself to sleep, enabling power savings. At the time of theexpected beacon the card wakes itself up and receives the beacon. The received beacon containsinformation about whether the Access Point or station has buffered frames for the card. If frames areavailable the card requests those frames until no more frames are available. The card then goes backto 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 thehost computer is operating on battery power. However, be aware that power save mode also resultsin lowered transmission and reception speed on the wireless LAN.
22Selecting the Ad Hoc ChannelWhen communicating in AdHoc or Pseudo AdHoc mode, you must specify a channel on whichcommunications will take place. To specify a channel, click the up or down arrow at the right of theAdHoc 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 theAccess Point.EncrptionThe Encryption menu lets you enable encryption and set the encryption keys. To see the availableencryption 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 EquivalentPrivacy (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 andstations that use the same encryption method and keys.
23Disabling EncryptionTo disable encryption, click the down arrow at the right of the Encryption field, select Disabled, andclick the Apply button.Enabling EncryptionTo enable encryption, click the down arrow at the right of the Encryption field, select either 64 bit or 128bit, and click the Apply button. After enabling an encryption method, you must then specify encryptionkeys, as described in the following sections.Creating Encryption Keys Using a PassphraseTo create encryption keys using a passphrase, click the radio button next to Create Key with Passphraseand type a character string in the Passphrase field. As you type, the Configuration Utility uses analgorithm to generate four keys used for encryption.When you finish typing your character string and click the Apply button, the Configuration Utility usesasterisks 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 ofyour wireless LAN.
24Creating Encryption Keys ManuallyIf you want, you can create encryption keys manually by clicking the radio button next to Create KeyManually, 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 musttype exactly 10 hexadecimal digits in each of the four key fields; for 128-bit encryption, you must typeexactly 26 hexadecimal digits. You then click the Apply button to create your encryption keys. Afteryou click the Apply button, the Configuration Utility uses asterisks to mask your keys.Default KeyThe Default Key field lets you specify which of the four encryption keys you use to transmit data onyour wireless LAN. You can change the default key by clicking on the down arrow at the right of thisfield, selecting the number of the key you want to use, and then clicking the Apply button. As long asthe 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.
25Link TabThe 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 inInfrastructure mode, this field shows the MAC address of the Access Point with which you arecommunicating. When operating in AdHoc mode, this field shows the virtual MAC address used bycomputers participating in the AdHoc network.• Current Channel: shows the channel on which the connection is made. In Infrastructure mode, thisnumber 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 iscontinuously 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 ofthe Beacon signal.You can click the Rescan button to force the radio to rescan all available channels. If your link qualityor signal strength is poor, rescanning can be used to push the radio off a weak Access Point andsearch for a better link with another Access Point.
26About TabThe 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 MACaddress of the PRISM card.
