Current Association States
Simplification to two states: associated, and unassociated.
Transition between the two states as needed
STA can only have zero or one AP in the associated state.
Unassociated
Associated

Add Third State
Called “Tentative Association”
Intermediate state between Associated and Unassociated.
In Tentative Association, communication is allowed between STA and AP, but not from STA to DS directly.
AP can act as proxy (EAP, etc.)
STA can have multiple APs in Tentative Association simultaneously.

How to Transition Between States Part 1
Explicit request to go from Unassociated to Tentative Association
Very similar to current association process, just no DS notification
Explicit request to go from Tentative Association to Associated
Triggers DS notification (if other conditions satisfied)

7. How to Transition Between States Part 2

May 2004
How to Transition Between States Part 2
Implicit transition from Associated to Tentative Association
Very similar to current deassociation process (currently mostly by voodoo)
Have explicit transition as well?
Timeout transition from Tentative Association to Unassociated
Need notification from AP to STA of timeout contract?
Periodic keepalive tickle from STA to AP?
