32Planning Your Wireless NetworkNetwork TopologyA wireless LAN is exactly like a regular LAN, except that each PersonalDigital Assistant (PDA) in the LAN uses an Instant Wireless™ WirelessNetwork CF Card to connect to the network using no wires.  PDAs in a wire-less LAN must be configured to share the same radio channel.The Instant Wireless™ Wireless Network CF Card provides LAN access forPDAs.  An integrated wireless and wired LAN is called an Infrastructure con-figuration.  A group of Network CF Card users and an Access Point composea Basic Service Set (BSS).  Each PDA equipped with a Network CF Card in aBSS can talk to any computer in a wired LAN infrastructure via the AccessPoint also allows you to synchronize the PDA through wireless connection.An infrastructure configuration extends the accessibility of a Network CF CardPDA to a wired LAN, and doubles the effective wireless transmission range fortwo Network CF Card PDAs.  Since the Access Point is able to forward datawithin its BSS, the effective transmission range in an infrastructure LAN isdoubled.The use of a unique ID in a Basic Service Set is essential.The Wireless LAN Infrastructure configuration is appropriate for enterprise-scale wireless access to a central database, or as a wireless application formobile users.Infrastructure mode also supports roaming capabilities for mobile users.  Morethan one BSS can be configured as an Extended Service Set (ESS).  This con-tinuous network allows users to roam freely within an ESS.  All Network CFCard PDAs within one Extended Service Set must be configured with the sameSSID.Selecting a feasible radio channel and optimum Access Point position is rec-ommended. Proper Access Point positioning combined with a clear radio sig-nal will greatly enhance performance.Roaming• One Instant Wireless™ Wireless Network CF Card• One Setup CD-ROM with Drivers and User Guide• One Registration Card (not shown)• Windows 9x or higher PC with CD-ROM (to load drivers)• PDA with available Type II CompactFlash Slot• Windows CEPackage ContentsSystem Requirements Instant WirelessTM Series Wireless Network CF Card
5Installing the DriversYour new Instant Wireless™ Wireless Network CF Card comes with an auto-mated software installation procedure that interacts with the Windows operat-ing system on your PC and the Windows CE operating systems on your PDA.This procedure automatically installs the drivers and Configuration Utilitywhile the Network CF Card is installed on your PDA.1. With the Network CF Card inserted into your PDA while your PDA is con-nected to your PC, insert the Setup CD into your PC’s CD-ROM drive.Unless you have deactivated the auto-run feature of Windows, the follow-ing screen should appear automatically.  If this screen does not appear automatically, you can access the installationby pressing the Start button and choosing Run.  In the drop down box pro-vided, type D:\setup.exe (where D: is the letter of your CD-ROM drive).Alternately, double-click My Computer, and then double-click the CD-ROM drive where the Setup CD is located.  Then double-click theSetup.exe icon that appears.Before You StartDriver InstallationWireless Network CF CardUnlike wired networks, wireless networks have two different modes in whichthey may be set up: Infrastructure and Ad-Hoc.  Choosing between these twomodes depends on whether or not the wireless network needs to share data orperipherals with a wired network or not.If the computers on the wireless network need to be accessible by a wired net-work or need to share a peripheral, such as a printer, with the wired networkcomputers, the wireless network should be set up in the Infrastructure mode.The basis of Infrastructure mode centers around an access point, which servesas the main point of communications in a wireless network.  Access pointstransmit data to PCsequipped with wirelessnetwork card, which canroam within a certainradial range of the accesspoint.  Multiple accesspoints can be arranged towork in succession toextend the roamingrange, and can be set upto communicate withyour Ethernet hardwareas well. If the wireless network is relatively small and needs to share resources onlywith the other computers on the wireless network, then the Ad-Hoc mode canbe used.   Ad-Hoc mode allows computers equipped with wireless transmittersand receivers to communicate directly with each other, eliminating the need foran access point.  The drawback of this mode is in the fact that, in Ad-Hoc mode,wireless-equipped computers are not able to communicate with computers ona wired network.And, of course,communicationbetween the wire-less-equipped com-puters is limited bythe distance andinterference directlybetween them.Ad-Hoc versus Infrastructure Mode4Instant WirelessTM Series

12You can save any of your configuration settings by setting up a Profile. To dothis, type the profile’s name in the Profile bar and click the Apply button tosave your changes under that profile.Mode allows you to choose between Infrastructure or Ad-Hoc, depending onyour network type. The Ad-Hoc mode is used for a simple peer-to-peer net-work and allows the sharing of local resources only between PDAs using theNetwork CF Card without needing an Access Point. The Infrastructure modeallows a wireless network to be integrated into an existing wired networkthrough an Access Point. Infrastructure networks permit roaming betweenAccess Points while maintaining a connection to all network resources.An acronym for Service Set Identifier, SSID is the unique name shared amongall points in a wireless network. The SSID setting must be identical for allpoints in the network. It is case sensitive and must not exceed 32 characters.The Transmit  Rate field shows the current transfer rate for the Network CFCard. To optimize performance and range, the Transmit Rate should be set toAuto Rate, which will automatically adjust the transfer speed for best perform-ance and longest range.Power Saving Enabled allows your PDA to enter "sleep" mode if your networkconnection experiences more than 1 second of no network activity. Thisdepends on PDA power saving mode.The Ad-Hoc Channel setting specifies the channel used in wireless communi-cation and should be set to the same channel as the other points in the wirelessnetwork. This setting can only be adjusted in Ad-Hoc mode.To undo any changes, click the Undo button. To use the default settings andeliminate those changes you’ve already made, click the Default button. To saveall of your changes, click the Apply button.

Wireless Network CF CardNote: Creating and using the passphrase is recommended for easy WEP con-figuration and security purposes.ENCRYPTIONThe 64-bit or 128-bit WEP keys can be generated here from a user-definedpassphrase or entered manually.An acronym for Wired Equivalent Privacy, WEP is an encryption scheme usedto protect your wireless data communications. WEP uses a combination of 64-bit or 128-bit keys to provide access control to your network and encryptionsecurity for every data transmission. To decode a data transmission, each pointin a network must use an identical 64-bit or 128-bit key.   Higher encryptionlevels mean higher levels of security, but, due to the complexity of the encryp-tion, they may mean decreased network performance. Instant WirelessTM Series

What is Ad-Hoc?An Ad-Hoc wireless LAN is a group of computers, each with a WLAN cardconnected as an independent wireless LAN. Ad hoc wireless LAN is applica-ble at a departmental scale for a branch or SOHO operation.What is Infrastructure?An integrated wireless and wired LAN is called an Infrastructure configura-tion. Infrastructure is applicable to enterprise scale for wireless access to cen-tral database, or wireless application for mobile workers.What is Roaming?Roaming is the ability of a portable computer user to communicate continu-ously while moving freely throughout an area greater than that covered by a sin-gle Access Point. Before using the roaming function, the workstation mustmake sure that it is the same channel number with the Access Point of dedicat-ed coverage area. To achieve true seamless connectivity, the wireless LAN must incorporate anumber of different functions. Each node and Access Point, for example, mustalways acknowledge receipt of each message. Each node must maintain contactwith the wireless network even when not actually transmitting data. Achievingthese functions simultaneously requires a dynamic RF networking technologythat links Access Points and nodes. In such a system, the user’s end node under-takes a search for the best possible access to the system. First, it evaluates suchfactors as signal strength and quality, as well as the message load currentlybeing carried by each Access Point and the distance of each Access Point to thewired backbone. Based on that information, the node next selects the rightAccess Point and registers its address. Communications between end node andhost computer can then be transmitted up and down the backbone.As the user moves on, the end nodes RF transmitter regularly checks the sys-tem to determine whether it is in touch with the original Access Point orwhether it should seek a new one. When a node no longer receives acknowl-edgment from its original Access Point, it undertakes a new search. Upon find-ing a new Access Point, it then reregisters, and the communication process con-tinues.What is BSS ID?A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in aBSS must be configured with the same BSS ID.1918Wireless Network CF CardTroubleshootingThis chapter provides solutions to problems usually occurring during the instal-lation and operation of the Network CF Card. Read the description below tosolve your problems. If you can’t find an answer here, check the Linksys web-site at www.linksys.com.1.My PDA does not recognize the Wireless CF Network Card.• Make sure that the Network CF Card is properly inserted into theCompactFlash port.• Make sure the link led is solid.2.The Wireless CF Network Card does not work properly.• Reinsert the Network CF Card into the PDA's CompactFlash port.• Uninstall the driver software from your PC and PDA device.• Restart your PC and repeat the hardware and software installation as speci-fied in this User Guide.3.I cannot communicate with the Access Point via Ethernet in theInfrastructure configuration.• Make sure that the Access Point is powered on.• Make sure that your Network CF Card is configured on the same channel,SSID, and WEP as the Access Point.What is IEEE 802.11b standard?The IEEE 802.11b Wireless LAN standards subcommittee, which is formulat-ing a standard for the industry. The objective is to enable wireless LAN hard-ware from different manufacturers to communicate. What IEEE 802.11b features are supported?The product supports the following IEEE 802.11b functions: • CSMA/CA plus Acknowledge protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management Common Problems and SolutionsFrequently Asked QuestionsInstant WirelessTM Series
Would the information be intercepted while transmitting on air?WLAN features two-fold protection in security. On the hardware side, as withDirect Sequence Spread Spectrum technology, it has the inherent security fea-ture of scrambling. On the software side, WLAN series offer the encryptionfunction (WEP) to enhance security and Access Control. Users can set it updepending upon their needs.Can Instant WirelessTM products support printer sharing?Instant WirelessTM products perform the same function as LAN products.Therefore, Instant Wireless™ products can work with NetWare, Windows2000, or other LAN operating systems to support printer or file sharing.What is WEP?WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bitshared key algorithm, as described in the IEEE 802.11b standard. 21What is ESS ID?An Infrastructure configuration could also support roaming capability formobile workers. More than one BSS can be configured as an Extended ServiceSet (ESS). Users within an ESS could Roam freely between BSSs while servedas a continuous connection to the network wireless stations and Access Pointswithin an ESS must be configured with the same ESS ID and the same radiochannel.What is ISM band?The FCC and their counterparts outside of the U.S. have set aside bandwidthfor unlicensed use in the ISM (Industrial, Scientific and Medical) band.Spectrum in the vicinity of 2.4 GHz, in particular, is being made availableworldwide. This presents a truly revolutionary opportunity to place convenienthigh-speed wireless capabilities in the hands of users around the globe. What is Spread Spectrum?Spread Spectrum technology is a wideband radio frequency technique devel-oped by the military for use in reliable, secure, mission-critical communica-tions systems. It is designed to trade off bandwidth efficiency for reliability,integrity, and security. In other words, more bandwidth is consumed than in thecase of narrowband transmission, but the trade off produces a signal that is, ineffect, louder and thus easier to detect, provided that the receiver knows theparameters of the spread-spectrum signal being broadcast. If a receiver is nottuned to the right frequency, a spread-spectrum signal looks like backgroundnoise. There are two main alternatives, Direct Sequence Spread Spectrum(DSSS) and Frequency Hopping Spread Spectrum (FHSS).What is DSSS? What is FHSS? And what are their differences?Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier thatchanges frequency in a pattern that is known to both transmitter and receiver.Properly synchronized, the net effect is to maintain a single logical channel. Toan unintended receiver, FHSS appears to be short-duration impulse noise.Direct-Sequence Spread-Spectrum (DSSS) generates a redundant bit patternfor each bit to be transmitted. This bit pattern is called a chip (or chippingcode). The longer the chip, the greater the probability that the original data canbe recovered. Even if one or more bits in the chip are damaged during trans-mission, statistical techniques embedded in the radio can recover the originaldata without -the need for retransmission. To an unintended receiver, DSSSappears as low power wideband noise and is rejected (ignored) by most nar-rowband receivers. 20Wireless Network CF CardInstant WirelessTM Series
22DSSS (Direct-Sequence Spread-Spectrum) - DSSS generates a redundant bitpattern for each bit to be transmitted. This bit pattern is called a chip (or chip-ping code). The longer the chip, the greater the probability that the original datacan be recovered. Even if one or more bits in the chip are damaged duringtransmission, statistical techniques embedded in the radio can recover the orig-inal data without -the need for retransmission. To an unintended receiver, DSSSappears as low power wideband noise and is rejected (ignored) by most nar-rowband receivers. Encryption - A security method that applies a specific algorithm to data inorder to alter the data's appearance and prevent other devices from reading theinformation. ESS - More than one BSS in a network.Ethernet - IEEE standard network protocol that specifies how data is placedon and retrieved from a common transmission medium. Having a transfer rateof 10 Mbps., this forms the underlying transport vehicle used by several upper-level protocols.FHSS - Also known as "Frequency Hopping Spread Spectrum". Frequencyhopping spread spectrum (FHSS) continuously changes the center frequency ofa conventional carrier several times per second according to a pseudo-randomset of channels, while chirp spread spectrum changes the carrier frequency.Because a fixed frequency is not used, illegal monitoring of spread spectrumsignals is extremely difficult, if not downright impossible depending on theparticular method.Firmware - Programming that is inserted into programmable read-only mem-ory (programmable read-only memory), thus becoming a permanent part of acomputing device. Fragmentation - Breaking a packet into smaller units when transmitting overa network medium that cannot support the original size of the packet. Unlike e-mail programs in which graphics and program files have to be"attached," FTP is designed to handle binary files directly and does not add theoverhead of encoding and decoding the data.Wireless Network CF CardGlossaryAd-hoc Network - An ad-hoc network is a wireless network or other small net-work in which some of the network devices are part of the network only for theduration of a communications session while in some close proximity to the restof the network.Backbone - The part of a network that connects most of the systems and net-works together and handles the most data.Bandwidth - The transmission capacity of a given facility, in terms of howmuch data the facility can transmit in a fixed amount of time; expressed in bitsper second (bps).Bit - A binary digit. The value - 0 or 1-used in the binary numbering system.Also, the smallest form of data.BSS (Basic Service Set) - A group of Network CF Card users and an AccessPoint.CompactFlash - A flash memory format card that plugs into a CompactFlashsocket or into a standard Type II PC Card slot with an adapter.  CSMA/CD (Carrier Sense Multiple Access/Collision Detection) - The LANaccess method used in Ethernet. When a device wants to gain access to the net-work, it checks to see if the network is quiet (senses the carrier). If it is not, itwaits a random amount of time before retrying. If the network is quiet and twodevices access the line at exactly the same time, their signals collide. When thecollision is detected, they both back off and each wait a random amount of timebefore retrying. Database - A database is a collection of data that is organized so that its con-tents can easily be accessed, managed, and updated. Driver - A software module that provides an interface between a network inter-face card and the upper-layer protocol software running in the computer.23Instant WirelessTM Series
24Passphrase - Used much like a password, a passphrase simplifies the WEPencryption process by automatically generating the WEP encryption keys forLinksys products.PC Card - A credit-card sized removable module that contains memory, I/O,or a hard disk. PDA - (Personal Digital Assistant) Any small mobile hand-held device that pro-vides computing and information storage and retrieval capabilities for person-al or business use.  Plug-and-Play - The ability of a computer system to configure expansionboards and other devices automatically without requiring the user to turn offthe system during installation.Port - A pathway into and out of the computer or a network device. For exam-ple, the serial and parallel ports on a personal computer are external sockets forplugging in communications lines, modems and printers. Roaming - The ability to use a wireless device and be able to move from oneaccess point's range to another without losing the connection.RTS (Request To Send) - An RS-232 signal sent from the transmitting stationto the receiving station requesting permission to transmit. Software - Instructions for the computer. A series of instructions that performsa particular task is called a "program." The two major categories of software are"system software" and "application software." System software is made up ofcontrol programs such as the operating system and database management sys-tem (DBMS). Application software is any program that processes data for theuser.A common misconception is that software is data. It is not. Software tells thehardware how to process the data.SOHO (Small Office/Home Office) - Market segment of professionals whowork at home or in small offices.Spread Spectrum - Spread Spectrum technology is a wideband radio frequen-cy technique developed by the military for use in reliable, secure, mission-crit-ical communications systems. It is designed to trade off bandwidth efficiencyfor reliability, integrity, and security. In other words, more bandwidth is con-Wireless Network CF CardHardware - Hardware is the physical aspect of computers, telecommunica-tions, and other information technology devices. The term arose as a way to dis-tinguish the "box" and the electronic circuitry and components of a computerfrom the program you put in it to make it do things. The program came to beknown as the software.IEEE - The Institute of Electrical and Electronics Engineers. The IEEEdescribes itself as "the world's largest technical professional society -- promot-ing the development and application of electrotechnology and allied sciencesfor the benefit of humanity, the advancement of the profession, and the well-being of our members." The IEEE fosters the development of standards that often become national andinternational standards. The organization publishes a number of journals, hasmany local chapters, and several large societies in special areas, such as theIEEE Computer Society.Infrastructure - An infrastructure network is a wireless network or other smallnetwork in which the wireless network devices are made a part of the networkthrough the Access Point which connects them to the rest of the network.ISM band - The FCC and their counterparts outside of the U.S. have set asidebandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical)band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made avail-able worldwide. This presents a truly revolutionary opportunity to place con-venient high-speed wireless capabilities in the hands of users around the globe.LAN - A local area network (LAN) is a group of computers and associateddevices that share a common communications line and typically shareresources within a small geographic area (for example, within an office build-ing). Mbps (MegaBits Per Second) - One million bits per second; unit of measure-ment for data transmission.Network - A system that transmits any combination of voice, video and/or databetween users. Packet - A unit of data routed between an origin and a destination in a network.25Instant WirelessTM Series
