Abstract: The present invention is based on the fundamental idea that, in many applications, the intended communication partner differs, such as by his position or other features, which are easily influenced by the user, from all other potential and unintended communication partners (third parties) in such a manner that the transmission features of the contactless interface (that is, for example, of the radio channel) between him/her and a first radio station (FS1), which is seeking to set up the connection, fulfill a specified quality criterion that is not fulfilled by all other potential communication partners or in such a manner that such a difference in the transmission features can be brought about at least by modifying at least one operating parameter of the first radio station (FS1).

Abstract: A navigation configuration is described that utilizes a communications network, an access device, a processing system central to the communications network, a navigation database connected thereto, a location determining device, a route control system connected to the route planning system and to the location determining device through the communications network, and an output device connected to the route control system through a media transfer device. The output device outputs local navigation information for directing a travel direction of a user.
