The minimumsystem configuration is the same as that required to run MS Windows (Windows95OSR2, 98, NT 4.0, 2000).Software EnvironmentThe stations operate in conjunction with most of the MS Windows (Windows95OSR2, 98, NT 4.0, 2000).
2 InstantWave High Speed USB AdapterWireless NetworkIn the IEEE 802.11 definition, a wireless network is classified as an Ad-Hocnetwork or an Infrastructure network.Ad-Hoc NetworkAn Ad-Hoc network is formed by a number of wireless stations (without an AccessPoint) communicating via radio waves. For the users, the shared resources on thewireless network appear exactly as they would on a regular wired network. Thewireless operation of the network is totally transparent. Figure 1 depicts a typicalAd-Hoc network scenario.Figure 1. An Ad-Hoc NetworkInfrastructure NetworkAn Infrastructure network is formed by several stations and one Access Point (AP),with the stations within range of the AP. Figure 2 depicts a typical Infrastructurenetwork topology.Figure 2. An Infrastructure NetworkServerWired ComputersAccess PointWireless Computers (USB Adapter)Wireless Stations
InstantWave High Speed USB Adapter 3Group ID/BSSIDA Group ID (the 802.11 standard uses the term BSSID) is the ID of a wireless cell.A wireless cell is usually made up of stations in an area that the radio signal cancomfortably cover. In other words, any wireless station in the cell cancommunicate with any other within reach of the radio signal (Figure 3).Figure 3. A Wireless Cell (Group)Domain Name/ESSIDA domain is usually defined by the network administrator as a segment/subnet of alarge network and may be made up of overlapping wireless cells. Wireless nodescan roam freely within the same domain without disconnecting from the network.Figure 4 depicts a common wireless network setup.Figure 4. Roaming in the Same DomainRoamingThe convenience of a mobile PC is the ability to move freely. The concept issimilar to that of a cellular phone moving from one base station to another.InstantWave High Speed offers built-in high performance seamless roamingcapabilities.Carrier SetInstantWave products use the unlicensed ISM (Industrial, Scientific, Medical) bandto communicate through radio waves. Different countries offer different radiofrequencies to be used as the ISM band. There are four frequency bands definedby 802.11: Japan (2.471GHz – 2.497 GHz), USA, Extended Japan, Canada, andEurope (2.4 GHz – 2.4835 GHz), Spain (2.445 GHz – 2.475 GHz), France (2.4465GHz – 2.4835 GHz). If a user wants to use InstantWave High Speed in a countrynot listed above, he/she needs to check with their government’s regulating body toAccess PointServerAccess PointWirelessStations

Incase of the Infrastructure Network Mode, the channel number is scannedautomatically. Need not to worry about setting the channel number. While incase of the Ad-hoc Network Mode, the channel number is set by the clent andcan be changed by the client later.• Current Tx Rate - Shows the current transmission rate on the adapter.• Signal Strength - Displays the measure of the signal strength level.• Rescan – The client will rescan the access point with the same domain nameon difference channel.WEP
InstantWave High Speed USB Adapter 23 Click the Encryption tab to view the Adapter WEP Properties (Figure 24). Figure 26. WEP Security • Use WEP - The WEP stands for Wired Equivalent Privacy. WEP is anencryption scheme that provides the secure wireless data communications tothe users. WEP uses a 40-bits key to control the network access. In order todecode the data transmission, each wireless client on the network must use theidentical 40-bits key.• WEP Key Generation - There are two ways of generating the WEP key. The first is by entering any text in the Passphrase. And click on Generate. It willgenerate four WEP keys as Key 1, Key 2, Key 3 and Key 4. You can select anykey for the security. If you do not select any key, key 1 is selected, as it is defaultkey. Then click on Write and it will update the registry and driver.Another WEP key generation method is by inserting the key values directly fromthe keyboard. And click on the write to update driver and Registry. Select the Key
24 InstantWave High Speed USB Adapternumber and use Key for accessing the Access Point. If the Key is not enteredcorrectly, a client cannot access the resources. As the wireless channel is moreprone to the illegal access, WEP provides users safe access. If the WEP key isenable on the AP, all client should be use the same WEP key with AP.

InstantWave High Speed USB Adapter 25 Network Watcher (Infrastructure)In an Infrastructure network, Network Watcher scans for all existing wireless cellsin range and displays the AP names, the MAC address, the Domain Name, theSignal Strength, the number of stations currently connected to each AP, and theconnection status. When Network Watcher is run, the program first reads anddisplays information stored in the database. The signal strength entry shows eitherGreen (strong signal), or Yellow (average signal). The information is notdynamically updated. To refresh the data click the Scan button. Network Watcheralso gives users the option of selecting an Access Point to join with manually.Figure 28. Network Watcher (Infrastructure)ScanClick Scan to obtain and display updated data. You may need to wait a short timedepending on the number of wireless cell replies received.JoinSelecting one of the APs from the list will enable the Join command. The Joincommand allows you to manually connect to a specific AP.If joining cannot be accomplished within 20 seconds (possibly due to an AP thathas gone off the air since the data was last refreshed, to RF interference, or a busyAP), the operation will fail. If this happens, you may try joining with the same APagain, or select another AP to join.Network Watcher (Ad-Hoc)On an Ad-Hoc network, Network Watcher displays all the wireless nodes (withtheir Computer Name and Node Address (MAC ID)s) that are currently connectedin the same Group as this station (Figure 29). The inactive timer counts the periodthat there is no traffic between it and the other connected stations.Figure 29. Network Watcher (Ad-Hoc)
