SYSTEM AND METHOD FOR ACCESSING A STRUCTURE USING DIRECTIONAL ANTENNAS AND A WIRELESS TOKEN
摘要
<p>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. 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.</p>
