SETTING THE COMMUNICATION DOMAIN
Setting the Communication Domain
Stationary Wireless PCs
The Basic Service Set (BSS) is the communication domain for each access point. For wireless PCs that do not need to support roaming, set the domain identifier (SSID) for the wireless card to the SSID of the access point you want to connect to. Check with your administrator for the SSID of the access point you should connect to.
Roaming Wireless PCs
A wireless infrastructure can also support roaming for mobile workers. More than one access point can be configured to create an Extended Service Set (ESS). By placing the access points so that a continuous coverage area is created, wireless users within this ESS can roam freely. All wireless adapters and access points within a specific ESS must be configured with the same SS ID and to the same radio channel.

Seamless Roaming
Before setting up an ESS for roaming, you need to choose a clear radio channel and ideal location for the access points to maximize performance. (Refer to “Troubleshooting” on page 24 for detailed information on installation and usage.)
