Geo-location is Unavailable

If an AP with a built-in GPS module does not report the geo-location after 30 minutes then do a GPS signal survey and find a better location for the AP. It is possible that some buildings shield the GPS signal and the GPS antenna. For more information, see Conduct a GPS Survey with a Smart Phone.

The Geo-Location Agent builds an AP graph of each floor plan that has an assigned access point. The graph is based on the FTM AP-to-AP ranging results, with the edges of the graph representing the estimated distances between the APs. The graph is placed on the map based on the geo-location reported by the anchor APs.

Note

The Geo-location Agent derives coordinates for the APs if the following conditions are met:

AP Graph Connectivity - Each AP on the floor must be able to determine the FTM distance to a minimum of three neighboring APs.
Number of anchor APs - The AP Graph must be connected to a minimum of four anchor APs

If the AP Graph Connectivity requirement is not met for all the APs on the floor, then the Geo-Location Agent creates several Sub-graphs or cliques, with each cliques including a subgroup of APs.The APs belonging to Sub-graphs can have geo-location coordinates assigned or not assigned.
