The following list describes some of themany applications made possible through the power and flexibility of wireless LANs:1. Difficult-to-wire environmentsThere are many situations where wires can not or not easily be laid. Historic buildings, older buildings,open areas and across busy streets make the installation of LANs either impossible or very expensive.2. Temporary workgroupsConsider situations in parks, athletic arenas, exhibitions, disaster-recovery, temporary office andconstruction sites where one wants a temporary WLAN established and removed.3. The ability to access real-time informatiosDoctors/nurses, point-of-sale employees, and warehouse workers can access real-time information whiledealing with patients, serving customers and processing information.4. Frequently changed environmentsShow rooms, meeting rooms, retail stores, and manufacturing sites where frequently rearrange theworkplace.5. Small Office and Home Office (SOHO) networksSOHO users need a cost-effective, easy and quick installation of a small network.

Wireless extensions to Ethernet networksNetwork managers in dynamic environments can minimize the overhead caused by moves, extensions tonetworks, and other changes with wireless LANs.7. Wired LAN backupNetwork managers implement wireless LANs to provide backup for mission-critical applications runningon wired networks.8. Training/Educational FacilitiesTraining sites at corporations and students at universities use wireless connectivity to ease access toinformation, information exchanges, and learning.1-6 Network ConfigurationsTo better understand how the wireless LAN products work together to create a wireless network, it mightbe helpful to depict a few of the possible wireless LAN PC card network configurations. The wireless LANproducts 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.Ad-hoc (peer-to-peer) ModeThis is the simplest network configuration that several computers equipped with the PC Cards that form awireless network whenever they are within range of one another (Figure 1-2). In ad-hoc mode, eachclient, is peer-to-peer, would only have access to the resources of the other client and requires no theaccess point. This is the easiest and least expensive way for the SOHO to set up a wireless network.Figure 1-2 A wireless Ad-hoc networkInfrastructure ModeThe infrastructure mode requires the use of an access point (AP). In this mode, all wireless

If used in stand-alone, the AP can extend the range of independent wirelessLANs by acting a repeater, which effectively doubling the distance between wireless stations as shown inFigure 1-3.Figure 1-3Extended-range independent WLAN using AP as repeaterIf wired to an Ethernet network as shown in Figure 1-4, the AP serves as a bridge and provides the linkbetween the server and the wireless clients. The wireless clients can move freely throughout thecoverage area of the AP while remaining connected to the server. Since the ap is connected to the wirednetwork, each client would have access to server resources as well as to other clients.Figure 1-4 Single AP bridgeAccess points have a finite range, on the order of 50 meters indoor and 100 meters outdoors. In a verylarge facility such as an enterprise, a warehouse, or on a college campus, it will probably be necessary toinstall more than one access point to cover an entire building or campus, as shown in Figure 1-5. In thisscenario, access points hand the client off from one to another in a way that is invisible to the client,ensuring roken connectivity. Wireless clients can roam seamlessly between different coverage areas andremain connected to the network.Wireless LAN PC CardWireless LAN Router/APLLInfrastructureWireless LAN PC Card Wireless LAN USB Adapter

You don’t have to buy an expensive router. Nor you have to buy several modems and setup phonelines. Just share one AP, one Modem, single dial-up account, and one phone line, dozens of networkusers can go surfing the Internet concurrently.Figure 1-6 Wireless router and IP SharingChapter 2 Installing Drivers & Client UtilityThis chapter describes how to install the PC Card drivers and client utility under Windows

19Chapter 4 TroubleshootingThis chapter describes the problems and corresponding solutions that may occur when installing a PCCard.Symptom SolutionWindows does notdetect the PC Card wheninstalled.Verify that the PC Card is properlyinserted into the PC Card slot.Check whether the computer has aPlug and Play BIOS.Windows 98/ME/2000/XP might notdetect the PC Card if a previousinstallation of the PC Card wascancelled before it was finished.Remove the previous driver, and redoThe installation again.Driver fails to load A resource conflict could exist.For Windows 98/ME/2000, use theDevice Manager to resolve resourceconflicts.Select System from the Control Panel,then click on the Device Manager tab.
20Device conflict on aWindows systemA device conflict under Windows98/ME/2000 may be related tothe PC Card.For Windows 98/ME/2000, use theComputer properties to identify theused I/O port addresses and IRQvalues.If there is a device conflict, selectalternative settings for I/O Base Addressor IRQ values. If you know which deviceis conflicting with the PC Card, you havethe option of changing that device’s I/Oaddress or IRQ instead of changing the PCCard.No resource conflicts weredetected, but the wirelessstation does not attach tothe networkVerify that the SSID of the PC Cardmatches that of the access point. Usethe Network Configuration PropertiesApplication in the Control Panel tomodify the SSID.Verify that the Network Mode of thePC Card is configured correctly.Nonfunctioning card LEDThe PC Card is not powered on. Thecause may be:y No Driver loaded or installed.y Card – Driver mismatch whichprevented the driver from loading.y Device conflict which preventedthe driver from loading.Actions:y Verify that a driver has beeninstalled.y Determine if there is a conflictwith another device.Weak signal orintermittent connection.Try reorienting the antenna. The PCCard antenna is attached to the endof the PC Card. For best use of theantenna:Keep the area around the antennaclear from materials that could blockradio transmission, such as metalobjects, electronic devices, andcordless telephones.If your signal is weak, change thedirection of the antenna slightly.If necessary, move your notebook
21computer a few inches to find a bettersignal.Use the Signal Strength display in theClient Utility to determine the best locationand orientation for a network connection.
