Abstract: A system and method for controlling access to a wireless networking system using RFID tags is provided. The security system and method uses RFID tags to determine the location of mobile computing device. The security system and method selectively allows access to the wireless networking system based on the determined location of the mobile computing device. For example, the security system and method will permit access to the wireless networking system if the mobile computing device is determined to be in an area of permitted access. Conversely, the security system and method will deny access to the wireless networking system if the mobile computing device is determined to be not within an area of permitted access. Thus, the system and method is able to effectively control access to the wireless networking system by only permitting access to mobile devices within designated areas.

Abstract: An object location system and method is provided for locating objects. The system includes an RFID reader, an angle calculator, and a distance calculator to determine which of a plurality of zones an object is located in or passing through. An RFID tag is affixed with the object that is to be located. The RFID reader transmits signals to the RFID tag and receives backscatter-modulated signals from the RFID tag at one or more RFID antennas. From those received signals, the angle calculator determines an angle of position of the RFID tag relative to the RFID antenna. From the angle of position the zone in which the object is located is determined.
