Question

ABC Company has deployed a Single Channel Architecture (SCA) solution to help overcome some of the common problems with client roaming. In such a network, all APs are configured with the same channel and BSSID. PEAPv0/EAP-MSCHAPv2 is the only supported authentication mechanism. As the Voice over Wi-Fi (STA-1) client moves throughout this network, what events are occurring?

Accepted Answer

The WLAN controller controls the AP to which STA-1 is associated and transparently moves this association in accordance with the physical location of STA-1.

Answer

STA-1 initiates open authentication and 802.11 association with each AP prior to roaming.

Answer

The WLAN controller is querying the RADIUS server for authentication before the association of STA-1 is moved from one AP to the next.

Answer

STA-1 controls when and where to roam by using signal and performance metrics in accordance with the chipset drivers and 802.11k.
