1. A computer-implemented method performed by a mobile device, comprising:

  • causing an application subsystem of the mobile device to receive a first location estimate of the mobile device in a geographic area, the first location estimate having a first accuracy;

    detecting a broadcast signal transmitted by a beacon located in the geographic area;

    processing the broadcast signal to determine a second location estimate of the mobile device in the geographic area that is more accurate than the first location estimate, the processing performed by a baseband subsystem of the mobile device, where the baseband subsystem consumes less power than the application subsystem; and

    processing the broadcast signal to determine services available to the mobile device in the geographic area.
