Abstract
A lockset with a latch assembly having a bolt movable between an extended position and a retracted position. The lockset includes a motor configured to move the bolt between the extended position and the retracted position. A controller is provided that is 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. The lockset includes a receiver connected to an antenna to detect an incoming wireless signal transmitted from an authentication device. 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. The controller is configured to control movement of the bolt between the extended and retracted positions based, at least in part, on the distance and the direction to the authentication device.
