Research output: Patent / Technischer StandardPatent


A method for access control wherein verification of access authorization is effected by evaluating an ID sent at regular intervals from a mobile electronic device or a data carrier nearest an access control device (3, 4, 5, 6), via bluetooth low energy standard as part of a “broadcasting”, to which at least one access authorization is unequivocally assigned, which is received by BLE transceiver units (TRX-1, TRX-2, TRX-3, TRX-4) connected to a computer comprising a CPU and storage located within range of the mobile electronic device or the data carrier. Localization of the mobile electronic devices or the data carriers is carried out by evaluation of the RSSI, wherein the signal strength is measured, with which that signal of a mobile electronic device or a data carrier is received, which contains the ID of BLE transceiver units (TRX-1, TRX-2, TRX-3, TRX-4).
