Enable
Calculation time
|
Select the
Enable check box to
initiate the calculation of the time required to compute location.
Note
|
This
parameter applies only to clients, rogue access points, rogue clients, and
interferers.
|
Caution
|
Enable this parameter only under Cisco TAC personnel guidance
because it slows down the overall location calculations.
|
|
Enable OW Location
|
Select the
Enable check box to
include Outer Wall (OW) calculation as part of location calculation.
Note
|
This parameter is ignored by
the MSE.
|
|
Enable
Data Accuracy Tool
|
Select
the
Enable check box to enable the Data Accuracy Tool.
This parameter is disabled by default.
Note
|
The
Data Accuracy Tool is a web application that displays in the MSE admin UI. Use
this tool to filter the devices outside the venue using location tuning,
maximum RSSI threshold, and based on stationary devices and MAC addresses.
To
use the Data Accuracy tool, enable the
Beta Features from the MSE admin UI. After the beta
features are enabled, scroll down to the bottom of the MSE admin UI and run the
tool. For more information about the Data Accuracy Tool, see
Using Data Accuracy Tool.

Relative discard RSSI time
|
Enter the number of minutes
since the most recent RSSI sample after which RSSI measurement should be
considered discarded. For example, if you set this parameter to 3 minutes and
the MSE receives two samples at 10 and 12 minutes, it keeps both samples. An
additional sample received at 15 minutes is discarded. The default value is 3.
Allowed values range from 0 to 99999. A value of less than 3 is not
recommended.
Note
|
This parameter applies only
to clients, rogue access points, rogue clients, and interferers.
|
|
Absolute discard RSSI time
|
Enter the number of minutes
after which RSSI measurement should be considered stale and discarded,
regardless of the most recent sample. The default value is 60. Allowed values
range from 0 to 99999. A value of less than 60 is not recommended.
Note
|
This parameter applies only
to clients.
|
|
RSSI Cutoff
|
Enter the RSSI cutoff value,
in decibels (dBs) with respect to one (1) mW (dBm), above which the MSE will
always use the access point measurement. The default value is –75.
Note
|
When 3 or more measurements
are available above the RSSI cutoff value, the MSE discards any weaker values
(lower than RSSI cutoff value) and use the 3 (or more) strongest measurements
for calculation; however, when only weak measurements below the RSSI cutoff
value are available, those values are used for calculation.
|
Note
|
This parameter applies only
to clients.
|
Caution
|
Modify only under Cisco TAC personnel guidance. Modifying this
value can reduce the accuracy of location calculation.
|
|
Enable Location Filtering
|
Location filtering is used to
smooth out the jitters in the calculated location. This prevents the located
device from jumping between two discrete points on the floor map.
|
Chokepoint Usage
|
Select
the
Enable check box to enable chokepoints to track Cisco
compatible tags.
|
Use
Chokepoints for Interfloor conflicts
|
Perimeter chokepoints or weighted location readings can be used
to locate Cisco compatible tags.
Options:
-
Never: When selected, perimeter chokepoints are not used to
locate Cisco compatible tags.
-
Always: When selected, perimeter points are used to locate Cisco
compatible tags.
-
Floor Ambiguity: When selected, both weighted location readings
and perimeter chokepoints are used to locate Cisco-compatible tags. If similar
locations are calculated by the two methods, the perimeter chokepoint value is
used by default.
|
Chokepoint Out of Range timeout
|
When a
Cisco compatible tag leaves a chokepoint range, the timeout period entered is
the period that passes before RSSI values are again used for determining
location.
|
Absent
Data cleanup interval
|
Enter
the number of minutes that data for
absent mobile stations is kept. An
absent mobile station is one that was discovered but does
not appear in the network. Default value is 1440.
|
Use
Default Heatmaps for Non Cisco Antennas
|
Select
this check box to enable the usage of default heatmaps for non-Cisco antennas
during the Location Calculation. This option is disabled by default.
|
Movement Detection
|
Individual RSSI change threshold
|
This
parameter specifies the Individual RSSI movement recalculation trigger
threshold.
Enter a
threshold value between 0-127 dBm.
Modify
only under Cisco TAC personnel guidance.
|
Aggregated RSSI change threshold
|
This
parameter specifies the Aggregated RSSI movement recalculation trigger
threshold.
Enter a
threshold value between 0-127 dBm.
Modify
only under Cisco TAC personnel guidance.
|
Many new
RSSI change percentage threshold
|
This
parameter specifies Many new RSSI movement recalculation trigger threshold in
percentage.
Modify
only under Cisco TAC personnel guidance.
