Abstract
The techniques described herein relate to a system for the localization of a terminal device using radio signals from radio access points that have been received in the terminal device. The system comprises a unit for providing localization information pertaining to the radio signals from the radio access points, whereby the localization information can be used for the localization of the terminal device. Moreover, the system comprises at least a first radio access point that is connected to the unit via a communication connection and that is configured in such a way that information that is representative of components of the localization information is transmitted to the unit. In this context, the first radio access point can acquire reference signal pattern data for a localization on the basis of pattern recognition, and the transmit power that can be employed for a lateration procedure. In addition to the system, the techniques described herein also proposes a method for the localization of a terminal device.
