Abstract
A wireless device access system that employs directional antennas for short-range wireless communication to detect the proximity and orientation of a user device with respect to a structure is disclosed. The access system receives and authenticates an unlock request and confirms the proximity and orientation of the user device prior to transmitting an unlock command to the structure. This authentication may occur through the use of substantially opposing directional antennas separated by a ground plane. Additionally, the wireless device may require the proximity of a user token prior to operation and/or the access system may include an override within the structure blocking any unlock command.
