Access control system with omni and directional antennas
First Claim
1. An access control system for monitoring an access point, comprising:
- a positioning unit for tracking locations of users relative to the access point using wireless signals generated by user devices carried by the users, wherein the positioning unit includes;
a primary antenna that receives the wireless signals from the user devices of the users;
a directional antenna that preferentially receives the wireless signals from the user devices from a threshold area of the access point; and
a processor for analyzing the wireless signals received by the primary antenna and the directional antenna for tracking the locations.

Abstract
An access control system and method for monitoring an access point are disclosed. Preferably, a positioning unit of the system includes a primary antenna and a directional antenna that determine close proximity of users to the access point while also allowing the system to continuously monitor the locations of the users. The primary antenna preferentially receives wireless signals sent from user devices (e.g. mobile phones, fobs) of the users while the directional antenna receives the wireless signals within a threshold area of the access point. The system authorizes users to enter each access point by matching user information of the users extracted from the wireless signals to locally stored user information for the users, and determining that the matched user information is referenced within locally stored authorization information indicating which users can access the access point. The system can pre-authorize the users as they approach the threshold area.

14. A method for controlling access of users to an access point, comprising:
-
tracking locations of users relative to the access point using wireless signals generated by user devices carried by the users via a positioning unit associated with the access point, the positioning unit tracking the locations by comparing the wireless signals received from a primary antenna and a directional antenna; and the positioning unit receiving user information for identifying the users to provide the access for the users. - View Dependent Claims (15, 16, 17, 18, 19, 20)
