Chapter 4 - Operation
The impact of the Hidden ESSID feature on the BU's operation is as follows:
When the BU receives Probe Request form an RB it will check if the ESSID in

the Probe Request is that same as its own ESSID. It will generate the Probe
Response only if there is a match.
The Authentication process is not affected by the Hidden ESSID feature.

When the BU receives an Association Request and the ESSID included in the

frame matches its own ESSID the BU sends the Association Response with
Status Code OK - meaning that the RB is associated. If there is no match the
BU sends the Association Response with Status code Rejected - meaning that
the RB is not associated, and the reason of rejection - wrong ESSID.
An RB that is trying to associate with BUs that are working with Hidden ESSID
will keep a list with BUs that rejected it. The BU will be kept in this list until the
Hidden ESSID Timeout expires for it or if the list is full and another BU that is not
in the list rejects the RB because of wrong ESSID.
The BU that is working with Hidden ESSID enable will keep a counter that will be
incremmented for each RB that is rejected because of wrong ESSID.
The Operator ESSID feature still works when Hidden ESSID is enabled. The only
differences is that the Runtime ESSID displayed by RB, when the RB is associated
because of Operator ESSID, will be the ESSID of the RB and not the ESSID of the
BU as it is when Hidden ESSID is disabled.
