Planning Your Wireless NetworkNetwork Topology

A wireless LAN is exactly like a regular LAN, except that each computer in theLAN uses an Instant Wireless™ Network PC Card to connect to the networkusing no wires. Computers in a wireless LAN must be configured to share thesame radio channel.

The Instant Wireless™ Network PC Card provides access to a wired LAN forwireless workstations. An integrated wireless and wired LAN is called anInfrastructure configuration. A group of Instant Wireless™ Network PC Cardusers and an Access Point compose a Basic Service Set (BSS). Each PCequipped with an Instant Wireless™ Network PC Card in a BSS can talk to anycomputer in a wired LAN infrastructure via the Access Point.

An infrastructure configuration extends the accessibility of an InstantWireless™ Network PC Card PC to a wired LAN, and doubles the effectivewireless transmission range for two Instant Wireless™ Network PC Card PCs.Since the Access Point is able to forward data within its BSS, the effectivetransmission range in an infrastructure LAN is doubled.

The use of a unique ID in a BSS is essential. All computers that have InstantWireless™ Network PC Cards configured without roaming options in an inde-pendent BSS must be configured with a BSS ID (that is used in the BSS).

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 InstantWireless™ Network PC Card PCs within one ESS must be configured with thesame ESS ID and use the same radio channel.

Before enabling an ESS with roaming capability, selecting a feasible radiochannel and optimum Access Point position is recommended. Proper AccessPoint positioning combined with a clear radio signal will greatly enhance per-formance.

6. A preamble is a signal usedto synchronize the transmis-sion timing between two ormore systems. A series oftransmission pulses is sentbefore the data to indicatethat "someone is about totransmit data". This ensuresthat systems receiving theinformation correctly inter-pret when the data transmis-sion starts. The PreambleMode should be set to Long(if in a “noisy” network envi-ronment), Short (if the envi-ronment is clear), or Auto (tolet the card interpret the envi-ronment). Click OK to fin-ish and continue to theIns ta l l ing Ne tworkProtocols section.

7. The RTS Threshold Valueshould remain at its defaultsetting of 2,432. Should youencounter inconsistent dataflow, only minor modifica-tions are recommended. ClickSSID to continue or the OKbutton to finish. If you chooseto finish now, continue to theI n s t a l l i n g N e t wo r kProtocols section.

CONFIGURATION

The Configuration screen allows you to customize the settings for the NetworkPC Card, the PCI Adapter, and your wireless network.

The Mode setting determines the architecture of your wireless network. SelectAd-Hoc or Infrastructure Mode depending on your network type. The Ad-Hoc mode is used for a simple peer-to-peer network and allows the sharing oflocal resources only between Network PC Cards without needing a wirelessAccess Point. The Infrastructure mode allows a wireless network to be inte-grated into an existed, wired network through an Access Point. Infrastructurenetworks permit roaming between Access Points while maintaining a connec-tion to all network resources.

An acronym for Service SetIdentifier, SSID is the uniquename shared among all pointsin a wireless network. TheSSID must be identical for allpoints in the network. It iscase sensitive and must notexceed 32 characters.

The Tx Rate field shows thecurrent transfer rate for theNetwork PC Card. To optimizeperformance and range, theTX Rate should be set to FullyAutomatic, which will auto-matically adjust the transferspeed for best performanceand longest range.

Power Saving Mode, or PS Mode, enables or disables the power saving featuresof your Network PC Card.

The Channel setting specifies the channel used in wireless communication andshould be set to the same channel as the other points in the wireless net-work.This setting can only be adjusted in AdHoc mode.

ENCRYPTION

The 40-bit or 128-bit WEP keys can be generated froma user-defined passphrase or entered manually.

An acronym for Wired Equivalent Privacy, WEP is anencryption scheme used to protect your wireless datacommunications. WEP uses a combination of 40-bit or128-bit keys to provide access control to your networkand encryption security for every data transmission. Todecode a data transmission, each point in a network must use an identical 40-bitor 128-bit key. When using 40-bit encryption, remember that it is identical toand compatible with 60-bit encryption. Higher encryption levels mean higherlevels of security, but, due to the complexity of the encryption, they may meandecreased network performance.

Encryption (WEP) can be setto Disabled, 40-bit, or 128-bit.Once enabled, you can createan encryption key by using aPassphrase, or by entering thekey manually.(The Passphrase method is rec-ommended; however, you mayneed to enter a manual key inorder to meet the requirementsof existing wireless equipmenton your network. If you areunsure, check your other wire-less PCs’ settings.)

The Passphrase can be anytext string with a maximum of31 alphanumeric charactersand is strongly recommendedbecause it is the easiest way to generate WEP keys.

Once you have chosen your key encryption method and entered either thePassphrase or manual key, click the Apply button. Then click the OK buttonand the encryption portion of the setup is complete.


Note: Pleasemake sure thateach point inyour wirelessnetwork is set atan identicalWEP value.

Note: Not all Wireless Access Points or Adapterssupport 128-bit WEP Encryption, which mayresult in network errors. Check your wirelessdevice’s documentation for more information.

3. I cannot communicate with the other computers linked via Ethernet inthe Infrastructure configuration.

• Make sure that the notebook PC to which the Network PC Card is associat-ed is powered on.

• Make sure that your Network PC Card is configured on the same channel andwith the same security options as with the other computers in theInfrastructure configuration.

Common Problems and Solutions

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.

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.

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.

What 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.
