1. A method comprising:
- receiving, by a system comprising a processor, from a mobile communication device, a wireless fingerprint corresponding to the mobile communication device and a subject area in which the mobile communication device is or was positioned, the wireless fingerprint comprising at least one signal strength value of at least one signal received by the mobile communication device from at least one transmitter associated with the subject area;
generating, by the system, based at least in part on the wireless fingerprint received from the mobile communication device, an area wireless signal distribution map for the subject area; and
determining, by the system, based at least in part on the wireless fingerprint and the area wireless signal distribution map, a location of the mobile communication device.

Abstract
A method comprising obtaining, by a system using a processor, a wireless fingerprint corresponding to a mobile communication device and a subject area in which the mobile communication device is or was positioned. The method also includes obtaining, by the system, an area wireless signal distribution map indicating wireless signal strength values corresponding to multiple wireless transmitters positioned in the subject area, and determining, by the system, based on the wireless fingerprint and the area wireless signal distribution map, a location of the mobile communication device.
