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 Service Set Identifier (SSID) for the wireless 
card to the SSID of the access point to which you want to 
connect. Check with your network administrator for the SSID.
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 SSID and 
to the same radio channel.
