Subgraph Statistics

Go to Monitor > Sites > Access Points > Geo Diagnostics, then select a floor plan under the Floor column to view subgraphs built within the boundaries of the floor plan. Next, select a graph under the Subgraph column to view related statistics.

The Subgraph Statistics display is divided into three panels:

All APs
Anchor APs
AP-to-AP Ranging

All APs

Following is a description of the information displayed under each column heading in the All APs panel.

AP Name — Unique name assigned to the AP
Set Time — Time at which the AP derived its geo coordinates from the Geo-Location Agent or GPS
Latitude — Latitude as derived from the Geo-Location Agent or GPS
Longitude — Longitude as derived from the Geo-Location Agent or GPS
Circular Error [m] — R95 measure (in meters) of the accuracy of a GPS receiver. For example, a Circular Error of 60 meters means that 95% of the time, the GPS position is within 60 meters of the true GPS location.
Height [m] — Height (in meters) at which the AP is installed above floor level
Anchor Type — Source from which the AP derived geo coordinates
FTM Ranges — Number of FTM-detected APs that are within range of the selected AP

Anchor APs

Following is a description of the information displayed under each column heading in the Anchor APs panel.

AP Name — Unique name assigned to the AP
Status — Available or Unavailable
Latitude — Latitude as derived from the Geo-Location Agent or GPS
Longitude — Longitude as derived from the Geo-Location Agent or GPS
Circular Error[m] — R95 measure (in meters) of the accuracy of a GPS receiver. For example, a Circular Error of 60 meters means that 95% of the time, the GPS position is within 60 meters of the true GPS location.
Source — GPS coordinates derived from third-party APP or integral GPS module.
Set Time — Time at which the AP derived its geo coordinates from the Geo-Location Agent or integral GPS

AP-to-AP Ranging

Following is a description of the information displayed under each column heading in the AP-to-AP Ranging panel.

Initiator — Unique name of an AP designated as initiator of FTM AP-to-AP ranging. An AP is designated as initiator when it ranks among the top 10 APs in the neighbor list with the highest RSSI value. Only neighboring APs that advertise a matching floor number of the initiator are considered in AP-to-AP ranging operations.
Responder — Unique name of an AP configured as responder in FTM AP-to-AP ranging operations. All indoor APs placed on AFC floor plans must adopt a profile that has FTM (11mc) responder support enabled. See Advanced Network Settings for details.
Distance — Distance between Initiator and Responder
Set Time — Time at which the distance measurement is recorded
Band — Band over which AP-to-AP ranging occurs
Channel Width[MHz] — Channel and channel width used by the initiator or responder, as applicable
