1. A non-transitory computer storage medium storing instructions configured to instruct a computing apparatus to perform a method, the method comprising:

  • measuring, by a mobile device, a radio frequency fingerprint;

    correlating the radio frequency fingerprint to a predetermined distribution of radio frequency fingerprints in a multi-floor environment;

    determining a first location determination result based on the correlating;

    measuring, by the mobile device, accelerations of the mobile device as a function of time;

    determining a second location determination result based on the accelerations;

    receiving, in the mobile device, a first beacon signal from a beacon device disposed at a first location of a transport corridor in the multi-floor environment and a second beacon signal from the beacon device;

    determining a first location of the beacon device based on the first beacon signal and a second location of the beacon device based on the second beacon signal; and

    computing a location of the mobile device based on the first location of the beacon device, the second location of the beacon device, the first location determination result, and the second location determination result.
