Patent ID: 11433854

Abstract:
An access control method in an access control system that comprises at least one access control device with an antenna (2, 3, 4). Verification of an access authorization is based on analysis of a beacon transmitted by a first wireless communication standard. The beacon contains an ID to which a unique identifier (TID) of the data carrier and a unique beacon ID of the data carrier (1) transmitting the beacon is assigned. The unique identifier and unique beacon ID allows positive beacon identification. The identification and localization of the data carriers (1) is realized by analyzing the RSSIs of the transmitted beacons. The unique beacon IDs ensure that the RSSI values of the same respective beacon of a data carrier (1) are used in the course of the RSSI analysis. The closest data carrier (1) is determined, during the RSSI analysis, and the transmitted ID is analyzed to grant access.
