1. A mobile device comprising a processor and a non-transitory computer-readable medium storing a set of instructions, the processor when executing the set of instructions causes the mobile device to:

  • wirelessly receive and measure a Received Signal Strength (RSS) of at least one signal emitted from each network access point in a subset of a plurality of network access points;

    determine a reduced area of a geographic area within which a location of the mobile device is likely to be by using;

    a radio map, stored in the mobile device, defining the geographic area by a plurality of reference points each characterized by the RSS of signals that are emitted from the plurality of network access points; and

    the measured RSS of the at least one signal emitted from each said network access point in the subset of the plurality of network access points;

    anddetermine the location of the mobile device based on;

    the determined reduced area; and

    compressive sensing applied to a set of RSS measurements selected from the group consisting of the measured RSS of the at least one signal emitted from each said network access point in the subset of the plurality of network access points;

    wherein the determined reduced area is determined by using a cluster matching algorithm or a tracking algorithm.
