Method and system for access control proximity location
First Claim
1. A security system, comprising:
- user devices that transmit wireless signals including packet data, wherein the packet data includes user information;
access points that provide access to restricted areas; and
positioning units located near the access points that include two or more antennas, wherein each of the positioning units receive the wireless signals from the user devices, and determine locations of the user devices relative to the access points,wherein each of the positioning units includes a first omnidirectional antenna that receives the wireless signals from the user devices when the user devices are located beyond a threshold area of the access points, and a directional antenna that receives the wireless signals from the user devices when the user devices are located within a threshold area of the access points.

Abstract
A system for a frictionless access control automatically identifies users and enables access to restricted areas of a building for example via access points such as locked doors. The system allows access when authorized users are in the vicinity of doors without requiring the users to swipe access keycards (or badges) at keycard terminals located at the doors, as in current systems. The system includes user devices such as key fobs and mobile phones that wirelessly broadcast user information and unique IDs for each of the devices in data packets, which are received by positioning units. The positioning units determine locations of the user devices, and send the packet data and the location data to a verification and tracking system. Preferably, the positioning units include two or more antennas that determine close proximity of users to access points while also allowing the system to continuously monitor the locations of the users.
