1. A method for controlling access within a secure control area using an access control device communicatively connected to one or more barrier(s) arranged within the secure control area, the method comprising:
executing ultra-wideband transmissions with one or more authentication devices using one or more ultra-wideband transceiver(s) of the access control device;
detecting, by a processing unit of the access control device, entry and/or exit of the one or more authentication devices through the barrier(s) by processing signal properties of the one or more ultra-wideband transmissions;
operating the barrier(s) by the access control device, in a first mode of operation, wherein in the first mode of operation, the access control device operates the barrier(s) such as to allow entry or exit irrespective of an authentication of the one or more authentication devices; and
switching operation of the barrier(s) by the access control device, from the first mode of operation into a second mode of operation upon determining a last exit of any authentication device from the secure control area, wherein in the second mode of operation, the access control device operates the barrier(s) such as to allow or deny entry of the one or more authentication devices into the secure control area in accordance with an access control process of the one or more authentication devices.
