Abstract: The present disclosure relates to computer-implemented methods and systems for determining the location of an access point. An example method may include receiving a plurality of data elements from a plurality of mobile devices. Each data element includes at least an indoor location of a respective mobile device. Each data element further includes a list of one or more radio frequency devices in the vicinity of the respective mobile device, and an indication of a signal strength between each of the one or more radio frequency devices in the vicinity of the respective mobile device and each respective mobile device. The method may also include analyzing the plurality of data elements to determine a location for a radio frequency device in the list of radio frequency devices. Furthermore, the method may include adding the determined location for the radio frequency device to a database.
