NETWORK CONFIGURATION ANDPLANNINGWN3501AR Wireless Solution supports a stand-alonewireless network configuration, as well as an integratedconfiguration with 10 Mbps Ethernet LANs.The WN3501AR USB adapter can be configured as: Ad hoc for departmental or SOHO LANs Infrastructure for enterprise LANsNetwork TopologiesAd hoc Wireless LANAn ad hoc wireless LAN consists of a group ofcomputers, each equipped with a wireless adapter,connected via radio signals as an independent wirelessLAN. Computers in a specific ad hoc wireless LANmust therefore be configured to the same radiochannel.An ad hoc wireless LAN can be used for a branchoffice or SOHO operation.23
Infrastructure Wireless LANThe WN3501AR can also provide access to a wiredLAN for wireless workstations. An integrated wiredand wireless LAN is called an Infrastructureconfiguration. A Basic Service Set (BSS) consists of agroup of wireless PC users, and an access point that isdirectly connected to the wired LAN. Each wirelessPC in this BSS can talk to any computer in its wirelessgroup via a radio link, or access other computers ornetwork resources in the wired LAN infrastructure viathe access point.The infrastructure configuration not only extends theaccessibility of wireless PCs to the wired LAN, butalso doubles the effective wireless transmission rangefor wireless PCs by passing their signal through one ormore access points.A wireless infrastructure can be used for access to acentral database, or for connection between mobileworkers, as shown in the following figure.24
Setting the Communication DomainStationary Wireless PCsThe Basic Service Set (BSS) is the communicationdomain for each access point. For wireless PCs that donot need to support roaming, set the domain identifier(SSID) for the wireless card to the BSS ID of theaccess point you want to connect to. Check with youradministrator for the BSS ID of the access point hewants you to connect to.Roaming Wireless PCsA wireless infrastructure can also support roaming formobile workers. More than one access point can beconfigured to create an Extended Service Set (ESS).By placing the access points so that a continuouscoverage area is created, wireless users within this ESScan roam freely. All Wireless adapters and WirelessAccess Points within a specific ESS must beconfigured with the same SS ID.Before setting up an ESS for roaming, you need tochoose a clear radio channel and ideal location for theAccess Points to maximize performance. (Refer toUsing the Wireless LAN Utility on page 15 fordetailed information on installation and usage.)25
