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 to which you want to connect. Check
with your administrator for the SSID of the access point to which
you should connect.
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.

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 23 for detailed
information on installation and usage.)
