An access system ( ) including an electronic key ( ) provided with a transmitter ( ) and including a secured location provided with a receiver ( ), the transmitter ( ) and the receiver ( ) being designed to communicate with one another to exchange authentication data. The transmitter ( ) transmits a signal; the receiver ( ) converts the transmitted signal into spectral data; and, in response to transmission of the authentication data, the access system ( ) grants access to the secured location, provided the spectral data matches the spectral signature of transmitter ( ).

Access system for vehicles

A device for data transmission in a motor vehicle and/or from a motor vehicle in its vicinity includes a first transceiver unit in or on the motor vehicle and a second transceiver unit. which is provided in at least one transponder unit whose spatial position relative to the vehicle may be variable or any desired position. In the first transceiver unit is a radar unit equipped for distance measurement, expanded by adding a two-channel data transmission system. The second transceiver unit is also a two-channel data transmission unit, and the microwave frequencies for two-channel communication of the data transmission system are selected so that their difference yields an intermediate frequency which is processable using conventional components in a heterodyne receiver in the reception part of each of the first and second transceiver units.
