Wireless lockset with integrated angle of arrival (AoA) detection

A method of detecting an authentication device for use with an electronic lockset, the method comprising:

• monitoring, by a controller of the electronic lockset, for an incoming wireless signal emitted from the authentication device, the electronic lockset including an interior assembly and an exterior assembly and only one of the exterior assembly or interior assembly includes an antenna;
• detecting, with a receiver and the antenna, the incoming wireless signal;
• analyzing, by the controller, wireless phase and timing information from the incoming wireless signal;
• determining, by the controller, distance and direction information representing a distance and direction to the authentication device through the analysis of the wireless phase and timing information;
• analyzing the distance and direction information to detect a pattern of movement of the authentication device;
• and
• controlling, via the controller, movement of a bolt between a locked position and an unlocked position positions based, at least in part, on the detected pattern of movement of the authentication device.

A lockset comprising:

• a latch assembly including a bolt movable between an extended position and a retracted position;
• a motor configured to move the bolt between the extended position and the retracted position;
• an interior assembly and an exterior assembly, wherein only the interior assembly includes an antenna;
• a controller configured to electronically control the motor to control movement of the bolt between the extended position and the retracted position responsive to receiving a valid authentication from an authentication device;
• a receiver connected to the antenna to detect an incoming wireless signal transmitted from the authentication device;
• wherein the controller includes an angle of arrival sensor configured to determine a distance and a direction to the authentication device by analyzing a wireless phase and timing of the incoming wireless signal transmitted by the authentication device;
• and
• wherein the controller is configured to control movement of the bolt between the extended and retracted positions based, at least in part, on detecting a pattern of movement of the authentication device determined by analyzing the distance and the direction to the authentication device.
