In this example, a single AT-WA7400 access point provides three wireless BSSID (Basic Service Set Identifier) access levels for an office. Each of these BSSIDs is associated with a different VLAN, which provides access to the Internet, the corporate network and restricted data.Visitors to the office are allowed to connect to the Internet using one BSSID, with no data encryption or user authentication. Employees can connect to the network via a second and third BSSID, so long as they have the correct user authentication.
