Infrastructure Network
An Infrastructure wireless network consists of at least one Access Point
connected to the wired network infrastructure and a set of wireless end stations.
The AP acts as a gateway, linking the wireless network to a wired LAN. As a
result, wireless stations have access to all of the features of your wired LAN
including e-mail, Internet, network printers and files server access.

Roaming Between Multiple Access Points
For large environments, multiple Access Points can be implemented to extend
the wireless service coverage area for seamless wireless access. It allows
wireless clients to roam from one AP to another while maintaining the wireless
connectivity at all times. A wireless client wandering across multiple APs will
automatically change the operating radio frequency as required.
In a roaming network, all APs and wireless clients must have the same Service
Set Identity (SSID) and security setting (if enabled). Alternatively the mobile
station may use an SSID of “any” to associate with any available AP, regardless
of the AP’s SSID. Roaming among different Access Points is controlled
automatically to maintain the wireless connectivity at all times.
