  • Patent number: 8866674
    Abstract: At a current position, a measurement packet is determined by a mobile terminal device at a measurement time. The measurement packet includes transmitter identifications of radio transmitters receivable at the current position of the mobile terminal device at the measurement time. By means of reference measurement packets provided to the mobile terminal device, the mobile terminal device itself can determine its current position. Additionally, a deviation of the determined transmitter identifications of the measurement packet from reference transmitter identifications of the reference measurement packets is determined.
    Type: Grant

  • Patent number: 8320938
    Abstract: When localizing terminal devices an updating measure of reference ambient information allocated to surroundings of the terminal device is executed when a deviation of ambient information determined by means of the terminal device from reference ambient information allocated to a position of the terminal device is detected.

  • Patent number: 8320280
    Abstract: An apparatus for determining a coincidence of a position with a reference position, wherein radio signals from fixedly positioned radio transmitters can be received at the position, having a provider for providing properties of the radio signals of the fixedly positioned radio transmitters at the position, wherein the provided properties of the radio signals include transmitter identifications identifying the radio transmitters, a separator for separating the radio transmitters into a first number of radio transmitters previously recorded transmitter identifications of which at the reference position are identical with transmitter identifications provided at the position, and into a second number of radio transmitters previously recorded transmitter identifications of which at the reference position and transmitter identifications provided at the position are different, and a determiner for determining a measure of matching for the position on the basis of the provided properties of the radio signals, wherein

  • Patent number: 8174447
    Abstract: An apparatus for localizing a position on a path, radio signals of fixedly positioned radio transmitters being receivable along the path, the apparatus including a determiner for determining properties of the radio signals of the fixedly positioned radio transmitters at the position, and a comparator for comparing the determined electromagnetic properties with previously recorded properties which characterize a reference path, and for determining a relation between the position and the reference path on the basis of a result of the comparison.
