Advanced Features for Wireless Analysis
Association Responses The number of Association Responses
observed on the wireless network. Access
points send Association Responses in response
to Association Requests from wireless stations.
Reassociation Requests The number of Reassociation Requests
observed on the wireless network. Stations
send Reassociation Requests when they need
to associate with a new access point (for
example, because they are out of range of their
old access point). This way, the new access
point knows to set up forwarding of traffic from
the old access point.
Reassociation Responses The number of Reassociation Responses
observed on the wireless network. Access
points send Reassociation Responses in
response to Reassociation Requests from
wireless stations.
Probe Requests The number of Probe Requests observed on the
wireless network. Stations send Probe
Requests to other stations or access points to
retrieve information (for example, to determine
whether a given access point is open for new
associations).
Probe Responses The number of Probe Responses observed on
the wireless network. Stations and access
points send Probe Responses containing
requested parameters in response to Probe
Requests.
Beacons The number of Beacon packets observed on the
wireless network. Access points send beacon
packets at a regular interval to synchronize
timing between stations on the same network.
ATIMs The number of Announcement Traffic Indication
Messages (ATIMs) observed on the wireless
network. Stations send ATIMs immediately after
a beacon packet transmission to inform other
stations that they have data to transmit to them.
Disassociations The number of Disassociation packets observed
on the wireless network. Stations and access
points send Disassociations to end
associations.
