1. A method comprising:

  • generating an initialized a position of a displacement device having motion sensors and at least one of a received signal strength indicator (RSSI) sensor and a round trip time (RTT) sensor;

    moving the displacement device within an environment to a plurality of measurement locations;

    determining at least one of a received signal strength and round trip time for wireless signals at each of the plurality of measurement locations;

    determining a position corresponding to each of the plurality of measurement locations based on the initialized position and data from the motion sensors; and

    storing in a database the at least one of the received signal strength and round trip time for wireless signals and corresponding position for each of the plurality of measurement locations.
