Abstract
A device connectable to a reader of an access control system includes an antenna, an ultra-wide band (UWB) front end circuit, a controller, and a communication link. The (UWB) front end circuit is connected to the antenna to facilitate UWB communication with a credential device. The controller is connected to the UWB front end and configured to perform ranging for the credential device using the UWB communication. The communication link is configured to interface with the reader.
Claims20
A device connectable to a reader of an access control system, the device comprising:
- an antenna;
- an ultra-wide band (UWB) front end circuit connected to the antenna to facilitate UWB communication with a credential device;
- a controller connected to the UWB front end circuit and configured to perform ranging for the credential device using the UWB communication;
- and
- a communication link configured to interface with the reader.
An integrated circuit connectable to a circuit board of a reader of an access control system, the integrated circuit comprising:
- an ultra-wide band (UWB) front end circuit connected to an antenna to facilitate UWB communication with a credential device;
- a controller connected to the UWB front end circuit and configured to perform ranging for the credential device using the UWB communication;
- and
- a communication link configured to interface with the reader.
An ultra-wide band (UWB) module connectable to a reader of an access control system, the UWB module comprising:
- an antenna;
- a communication link configured to interface with the reader;
- an ultra-wide band (UWB) front end circuit connected to the antenna to facilitate UWB communication with a credential device;
- and
- a controller connected to the UWB front end circuit and configured to perform ranging for the credential device using the UWB communication upon receipt of data associated with the credential device from the reader over the communication link.
