Select the Fast BSS Transition option to enable 802.11r fast BSS transition support.
Fast BSS (802.11r) is an attempt to undo the burden that security and QoS added to the handoff
process, and restore it back to an original four message exchange process. The central application
for the 802.11r standard is VOIP using mobile phones within wireless Internet networks.
