1.3 Network Service Set Identification (SSID) Overview
On a wireless network, a mobile user can roam freely within the service area of the
Access Point with the same service Set Identification SSIDs without losing
connection to the wired network. In order for a mobile unit to roam seamlessly from
one Access Point to another, the SSIDs of all Access Points and the wireless LAN
cards must be the same.
Assigning SSIDs, can provide the following security:

To avoid different user-groups from accessing network resources other than their
own.

Ensure each user-group has access within its own network.

Assure different user-group has the same access to Ethernet segment.
Figure 3 illustrates the use off SSIDs in an environment containing multiple
infrastructure network configured to communicate in the same Ethernet segment.
SSIDs assure the 3 users of Group A can only access each other, but not other
infrastructure, such as Group B.
