Roaming 

Multiple Access Points can be installed to extend the wireless service coverage area for 
seamless wireless access. Within an extended service area, all Access Points and wireless 
clients must have the same Service Set Identity (SSID). Roaming among different Access 
Points is controlled automatically to maintain the wireless connectivity at all times.
