NOTE:
The RSSI is an average of the last 20 RSSI samples. The RSSI value is reset every time the radio
returns to scanning mode.
2.5.6 Mobility Configuration Menu
A mobile environment requires special considerations that are not a factor in fixed installations. Use the fol-
lowing menu to set Remote radios for mobile operation.

•
Mobility Mode
—Selects whether or not mobility-specific parameters are active. [
enabled, disabled;
disabled
]
•
Blacklist Timer
—Sets/displays the number of seconds an AP stays on the blacklist after association
is lost. [
10-120; 10
]
•
Settling Timer
—Sets/displays the number of seconds the radio waits before evaluating the signal
quality of a newly acquired AP. [
5-120; 10
]
•
RSSI Assoc Threshold
—Level (dBm) that a Remote must read to determine whether or not to asso-
ciate to an AP while in Mobility Mode.
[0 to -120; -120]
•
RSSI Assoc Backoff Time
—Adjust the RSSI Assoc Threshold after scanning continues for this
amount of time, repeating every specified number of seconds. A setting of
0
disables the feature.
[0 – 120 seconds; 0]
•
RSSI Assoc Backoff Step
—Amount to adjust the RSSI Assoc Threshold at every backoff time.
[-10 to -1 dBm; -1]
•
RSSI Disassoc Threshold
—Level (dBm) that a Remote will use to determine when to drop from its
current AP if the signal becomes too degraded.
[0 to -120; -90]
After association is lost with an AP, and scanning for an alternate AP is started, the former AP is placed on
a “blacklist” to avoid linking immediately back to the same AP. Once the blacklist timer has expired, if no
alternate AP is found, a link will be attempted with the same AP as before.
An Access Point is added to the blacklist when the Remote detects that the RSSI has dropped below the
RSSI
Disassoc Threshold
and should try to find an alternate AP to connect to.
An Access Point is removed from the blacklist table when it has been in the table longer than the time set
by the
Blacklist Timer
.
When mobility is enabled and beacon learning is on association, the dropped AP’s channels are excluded
from scanning during the blacklist time.
