sent the Probe Request, and it is sent only if the ESSID received in the Probe
Request is the same as the AU's ESSID.
The ESSID will be present also in the Association Request frame sent by SUs.
The impact of the Hidden ESSID feature on the SU's operation is as follows:
If the Hidden ESSID Support parameter in the SU is set to Disable, the SU will
not try to Associate with an AU that is working with Hidden ESSID Enabled
If the Hidden ESSID Support parameter in the SU is set to Enable the SU will
try to Associate with an AU that is working with Hidden ESSID. The SU will
send the Association Request that will contain the ESSID of the SU; the AU
will check the SU's ESSID versus its own ESSID and if there is a match the AU
will associate the SU. If the SU uses a different ESSID the AU will reject it and
the Association Response will include the reason for rejection. The SU will add
this AU to a table that contains the AUs that rejected it because of wrong
ESSID and it will not try again to associate with this AU until the Hidden
ESSID Timeout expires.
If Hidden ESSID Support parameter in the SU is set to Enable and the SU
finds an AU that is not working with Hidden ESSID the SU will try to associate
with this AU only if the AU's ESSID/Operator ESSID is the same as the SU's
ESSID.
The impact of the Hidden ESSID feature on the AU's operation is as follows:
When the AU receives Probe Request form an SU 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 AU receives an Association Request and the ESSID included in the
frame matches its own ESSID the AU sends the Association Response with
Status Code OK - meaning that the SU is associated. If there is no match the
AU sends the Association Response with Status code Rejected - meaning that
SU is not associated, and the reason of rejection - wrong ESSID.
An SU that is trying to associate with AUs that are working with Hidden ESSID
will keep a list with AUs that rejected. The AU will be kept in this list until the
