  • Apparatus and method for determining a current position of a mobile device
    Patent number: 7783302
    Abstract: An apparatus for determining a current position of a mobile device in an environment in which at least one transmitter is disposed includes a means for providing a cartographic map of the environment, the cartographic map including field strength reference values at reference points, a means for determining a field strength value, a means for deriving a reference point within reach that can be reached starting from a previous position of the mobile device by movement of the mobile device in the environment within a predetermined time interval, from the cartographic map of the environment, and a comparator for comparing the field strength value with a field strength reference value at the reference point within reach in order to determine the current position. By including the cartographic map of the environment, the position determination is simplified.
