Patent ID: 11475725

Abstract:
Device, method, and computer program product for access control, the device comprising an ultra-wideband transceiver (12) connected to a first electronic circuit (11); wherein the first electronic circuit (11) is configured to activate (S1) periodically the ultra-wideband transceiver (12) to receive ultra-wideband transmissions (T) from a mobile device (2), upon reception (S2) of an ultra-wideband transmission (T) from a mobile device (2), to activate the ultra-wideband transceiver (12) to transmit (S3) to the mobile device (2) a reguest message and to receive (S5) from the mobile device (2) a response message, to determine (S6) a distance (d) of the mobile device (2) from the access control terminal (1), using the response message, and to execute access control, if the mobile device (2) is within a pre-determined proximity range (P).
