Fast Transition Roaming: 802.11r

The 802.11r standard is designed to permit continuous connectivity for devices in motion. 802.11r addresses the fast roaming and fast BSS transitions.

The key consideration is the roaming delay penalty imposed by the lengthy handshake between the supplicant, authenticator, and authentication server in WPA or WPA2 enterprise mode. 802.11r minimizes the loss of connectivity to the wireless distribution system during such BSS transitions, thus preventing degradation of voice quality.

To take advantage of 802.11r, your access points and B3000n badges must be configured to enable 802.11r. You can use a WPA2-Pre Shared Key passphrase, EAP-FAST, EAP-PEAP or EAP-TLS authentication. For more information on how to configure badges for 802.11r, refer to Vocera Badge User Guide.

Note: B3000n badges support 802.11r over-the-air or over-the-DS (Distribution System). Select the corresponding options on the AP and badge properties accordingly.
