The following list describes some of the manyapplications 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 andacross 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 and construction sites whereone wants a temporary WLAN established and removed.3. The ability to access real-time informationDoctors/nurses, point-of-sale employees, and warehouse workers can accessreal-time information while dealing with patients, serving customers and processing information.4. Frequently changed environmentsShow rooms, meeting rooms, retail stores, and manufacturing sites where frequently rearrange the workplace.5. Small Office and Home Office (SOHO) networksSOHO users need a cost-effective, easy and quick installation of a small network.
26. Wireless extensions to Ethernet networksNetwork managers in dynamic environments can minimize the overhead caused by moves, extensions to networks, andother changes with wireless LANs.7. Wired LAN backupNetwork managers implement wireless LANs to provide backup for mission-critical applications running on wired networks.8. Training/Educational FacilitiesTraining sites at corporations and students at universities use wireless connectivity to ease access to information, information exchanges,and learning.1- 6 Network ConfigurationsTo better understand how the wireless LAN products work together to create a wireless network, it might be helpfulto depict a few of the possible wireless LAN USB Adapter network configurations. The wireless LAN products canbe 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 USB Adapters that form awireless network whenever they are within range of one another. In ad-hoc mode, each client, is peer-to-peer,would only have access to the resources of the other client and requires no the access point. This is the easiestand least expensive way for the SOHO to set up a wireless network.Infrastructure ModeThe infrastructure mode requires the use of an access point (AP). In this mode, all wireless communicationsbetween two computers have to be via the AP no matter the AP is wired to Ethernet network or stand-alone. If usedin stand-alone, the AP can extend the range of independent wireless LANs by acting a repeater, which effectivelydoubling the distance between wireless stations.If wired to an Ethernet network, the AP serves as a bridge and provides the link between the server and thewireless clients. The wireless clients can move freely throughout the coverage area of the AP while remainingconnected to the server. Since the AP is connected to the wired network, each client would have access to serverresources as well as to other clients.Access points have a finite range, on the order of 50 meters indoor and 100 meters outdoors. In a very large facilitysuch as an enterprise, a warehouse, or on a college campus, it will probably be necessary to install more than oneaccess point to cover an entire building or campus. In this scenario, access points hand the client off from one toanother in a way that is invisible to the client, ensuring unbroken connectivity. Wireless clients can roam seamlesslybetween different coverage areas and remain connected to the network.Wireless Router and IP SharingIn infrastructure mode, in addition to acting as a bridge between an Ethernet and wireless network, the AP can beconfigured as a wireless router and IP sharing device for Internet access . You don’t have to buy an expensiverouter. Nor you have to buy several modems and setup phone lines. Just share one AP, one Modem, single dial-upaccount, and onePhone line, dozens of network users can go surfing the Internetconcurrently.

In orderto change the configuration parameters press the “Change” button, make your changes and then press “Submit” in order tosave your changes. Operating Mode:y Adhoc – this is non-standard peer-to-peer mode of operation and requires no the Access Point. When wireless clientsare operated in this mode, all wireless clients require the same channel number and don’t care the SSID.y Infrastructure: this mode of operation requires the use of an Access Point. In this mode, all wireless communicationsbetween computers have to be via the Access Point. (Default setting is Infrastructure)y Channel: select the operating radio frequency channel in AdHoc or Infrastructure mode.y SSID: is an identification code required for communication in a wireless LAN. You will only be able to connect with awireless client (AdHoc) or an Access Point (Infrastructure) which has the same SSID. If the SSID of a USB Adapter is set asany, then the USB Adapter is possible to be connected to all available Access Point.y Tx Rate: the data speed that wireless client is transmitting.y Power Mgmt Mode: Power save function disabled or enabled. (Default setting is Active)y MAC Address: every network adapter has a unique number different from other adapters in the network.y Status: shows status information about the radio link. Associated BSSID: means the wireless client is connected to an access point. BSSID is shown in the form of sixhex digits which is the MAC address of the access point. Scanning: means the wireless client is searching for an available access point in infrastructure mode. Disconnected: means there are no access points or other wireless clients (if communicating in Ad-hoc mode), orthe USB Adapter is unplugged in your computer.y Signal Strength: The bar shows signal strength level. The higher blue bar is, the morepowerful radio signal is received by the USB Adapter .y Link Quality: The bar shows the measured signal level and connection status. The higher blue bar is, the better is radiosignal received by the USB Adapter.StatisticsThis option enables you to view the available statistic information (Data packets, Management Packets and Rejected packets).In order to renew or update this list of statistics, press the “Clear” button. In order to exit press the “Exit” button at the bottom ofthe screen.Site SurveyBy choosing the Site Survey option in any of the two modes, you can scan all the channels in order to find all the access pointswithin the range of your card.
