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.
Claims13
A device comprising:
- at least one antenna;
- an ultra-wide band (UWB) front end circuit connected to the at least one 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;
- a wired communication link configured to interface a reader of an access control system;
- and
- a housing separate from a housing of the reader, the housing of the device accommodating the antenna, the UWB front end circuit, and the controller.
A device comprising:
- at least one antenna;
- an ultra-wide band (UWB) front end circuit connected to the at least one 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;
- a wireless communication link configured to interface a reader of an access control system, wherein the controller is configured to communicate with the reader over the wireless communication link using near-field communication (NFC);
- and
- a housing separate from a housing of the reader, the housing of the device accommodating the antenna, the UWB front end circuit, and the controller.
A device comprising:
- at least one antenna;
- an ultra-wide band (UWB) front end circuit connected to the at least one 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;
- a communication link configured to interface a reader of an access control system, wherein the communication link is configured to connect to an expansion port or expansion slot of the reader;
- and
- a housing separate from a housing of the reader, the housing of the device accommodating the antenna, the UWB front end circuit, and the controller.
A device comprising:
- at least one antenna;
- an ultra-wide band (UWB) front end circuit connected to the at least one 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;
- a communication link configured to interface a reader of an access control system;
- and
- a housing separate from a housing of the reader, the housing of the device accommodating the antenna, the UWB front end circuit, and the controller;
- wherein the controller and the UWB front end circuit receive power from the reader.
