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.
