Abstract
A method includes a mobile device receiving data from a first beacon in a plurality of beacons, wherein the data indicates a plurality signals strengths of signals received by the first beacon from the other beacons in the plurality of beacons. The mobile device uses multivariable regression based on the data received from the first beacon and signal strengths of signals received by the mobile device from the other beacons in the plurality of beacons to determine distances from the mobile device to the beacons. The mobile device determines a location of the mobile device based on the determined distances.
