  • Patent number: 9217788
    Abstract: A location and tracking system has wireless base stations, an input interface, and a processor. It receives initial physical environment inputs for an environment, with default signal attenuation values for wall and obstacle segments. An initial channel parameters fingerprint of projected signal strengths in the environment is generated according to the initial physical environment model. The processor simulates motion of the node along a hth trajectory to create a corresponding fitness function describing how similar the channel parameters estimated along the hth trajectory by the prediction model are to gathered channel parameters by the mobile node along its trajectory. The model and the fingerprint are subsequently modified in iterations as possible mobile node trajectories are determined to perform location error estimation which takes into account the re-calculated fingerprint and gathered channel parameters and the hth trajectory as a ground truth.

  • Publication number: 20120007779
    Abstract: A location and tracking system (1) comprises a site survey tool (2), a location engine (3), a self-calibration engine (4), and a fingerprint database (5). The system (1) operates for a wireless network of access points in a building and it generates from initialization data a model of the physical environment. The model may for example be in the form of data representing geometry of lines in plan and signal attenuation values for the lines. The system then uses this model to generate a fingerprint of projected signal strengths in the environment. The system may maintains a fingerprint for every environment model or there may be only one model at any one time, or there may be a number. Where the latter, the system may assign a weighting to each model to indicate its confidence value.
