Infrastructure Wireless LAN for Roaming Wireless PCs
The Basic Service Set (BSS) is the communications domain for each Wireless 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 he wants you to
connect.
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 network cards, adapters, and wireless access points
within a specific ESS must be configured with the same SSID.
