Abstract

A method and a device for allocating an authentication device to a base station, with the base station delivering a search signal which is received by the authentication device and is compared with a previously stored reference signal assigned to a base station. If the search signal matches a reference signal, the authentication device sends a response signal. If they do not match, the authentication device checks whether the search signal matches another previously stored reference signal allocated to another base station.
