1. A sensor network system comprising:

  • a plurality of sensors at known locations, each sensor having a microcell and capable of communicating wirelessly with a personal digital key (PDK) in its microcell and gathering position data about such PDK, the PDK containing a memory having service blocks, each service block accessible by a corresponding service block access key;

    a sensor management module (SMM) communicatively coupled to the plurality of sensors and configured to facilitate communication with one or more applications;

    wherein the SMM and the sensor provide a data path between a service block on the PDK and an application that has access to the corresponding service block access key; and

    the SMM receives the position data gathered by the sensors about a PDK, generates location tracking data for the PDK based on the position data and makes the location tracking data available to applications.
