1. A method for communication signal-based position determination of objects in road traffic, comprising the steps of:

  • transmitting wirelessly at least one data-transporting communication signal by at least one sender,wherein the at least one communication signal is reflected at least proportionally as a reflection signal by at least one object,receiving the at least one communication signal and the reflection signal by a receiver, and wherein the receiver determines a location of the at least one sender,determining a propagation time difference between the communication signal and the reflection signal by the receiver and a location of the object by the receiver,determining at least one Doppler frequency by mixing the at least one communication signal with an associated one of the reflection signal,the receiver, as a result of temporal observation of a change in the Doppler frequency, assigning thereto a relative-speed-dependent distance curve, the profile of the curve containing the position of at least one of the objects.
