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 comprising:
- an antenna;
- a communication link configured to interface with a reader of an access control system;
- 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 upon receipt of data associated with the credential device from the reader over the communication link;
- and
- a device housing separate from a housing of the reader, the device housing containing the antenna, the UWB front end circuit, and the controller.
An integrated circuit (IC) connectable to a circuit board, 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 communication link configured to interface with a reader of an access control system;
- 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;
- and
- an IC housing separate from a housing of the reader of the access control system, the IC housing containing the antenna, the UWB front end circuit, and the controller.
An ultra-wide band (UWB) module comprising:
- an antenna;
- a communication link configured to interface with a reader of an access control system;
- 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 upon receipt of data associated with the credential device from the reader over the communication link;
- and
- a module housing separate from a housing of the reader, the module housing containing the antenna, the UWB front end circuit, and the controller.
