I'm building an application that needs to know whether the currently connected BSSID is a part of a larger network that is restricted to a building.
For example, if I pull an access point's BSSID on one floor, how can I determine (without doing a tedious full-building WiFi walk-through survey) that this BSSID is part of the same network that the rest of the building is using?
I have considered using just the SSID, but this provides problems if two buildings are using the same SSID.
Any help would be greatly appreciated!
