1. Automated Self-Healing Network Each Wi-Fi location transaction starts with a scan for nearby access points. The resulting access point information is then compared against the central reference network. Known access points (those already in the reference network) are used to calculate the location of the device.
Any access point that is either not in the database or was previously associated with a different geographic location is automatically identified and its current position entered into the database. In this manner, XPS automatically fixes and expands the Wi-Fi reference network as it is being used.
