•
Mobility Mode
—Selects whether or not mobility-specific param-
eters 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
]
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 imme-
diately back to the same AP. 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 Threshold
set in the Radio Config-
uration menu 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
.
Additional Considerations for Mobile Operation
The following key points should be considered for all mobile installa-
tions:
• Use middleware—The use of middleware in the mobile laptops is
highly recommended for better operation of a mobile data system.
GE MDS provides middleware from one of the vendors in this mar-
ket. Contact your factory representative for details.
• Plan your network coverage—Deploy Access Points so that they
provide overlapping coverage to each other. Access Points must use
the same network name to enable roaming.
