Abstract: A device for checking access permissions includes an access area with guidance devices for forming an access lane for separating people or objects, in which blocking and/or signal means define an access threshold. A gate controller having a Bluetooth radio interface allows an access permission to be read from mobile data carriers, and positive validation of the access permission results in the access controller releasing the blocking and/or signal means and thus allowing separate passage through the access threshold. An access lane has an associated multiphase antenna group, the transmission/reception antennas of which are actuated by a Bluetooth transceiver module via an antenna feed network in such a way that at least two antenna lobes form that are at different distances from the access threshold as seen in the direction of access.
