Mobile device location estimation

A non-transitory, computer-readable medium storing computer instructions executable by a computer to perform operations comprising:

• using indoor floor map, indoor WLAN AP location map and/or constructing a pseudo-access point (AP) map associated with an indoor location, wherein the pseudo-AP map includes at least one pseudo-AP, each pseudo-AP a function of at least a radio-frequency (RF) signal strength indication (RSSI) associated with at least one actual AP associated with the indoor location;
• estimating a mobile device location within boundaries of the indoor location using:
• at least one actual AP associated with the indoor location, and
• at least one pseudo-AP from the pseudo-AP map associated with the indoor location;
• and
• using the estimated mobile device location for indoor navigation within the indoor location.

A system, comprising:

• a memory;
• at least one computer interoperable coupled with the memory and configured to:
• use indoor floor map, indoor WLAN AP location map and construct a pseudo-access point (AP) map associated with an indoor location, wherein the pseudo-AP map includes at least one pseudo-AP, each pseudo-AP a function of at least a radio-frequency (RF) signal strength indication (RSSI) associated with at least one actual AP associated with the indoor location;
• estimate a mobile device location within boundaries of the indoor location using:
• at least one actual AP associated with the indoor location, and
• at least one pseudo-AP from the pseudo-AP map associated with the indoor location;
• and
• use the estimated mobile device location for indoor navigation within the indoor location.
