Infrastructure Mode
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
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.
