Abstract
A wireless access control system for a door may include a lock assembly carried by the door that may include a lock, lock wireless communications circuitry, a proximity detector directed toward an interior area, interior and exterior antennas, and a lock controller. The lock controller may determine if the user is in the interior or exterior area based upon the proximity detector and a received signal strength at the interior and exterior antennas based upon wireless communication with a remote access device, enable lock switching based upon the received signal strength at the exterior antenna being greater than at the interior antenna, disable lock switching when the user is in the interior area and a difference between the received signal strength at the interior and exterior antennas is below a threshold, and switch the lock based upon communication with the remote access device and switching of the lock being enabled.
