RFID based security network
First Claim
1. A security network for use in a building with an opening to be monitored for intrusion comprising:
- an intrusion sensor monitoring the opening;
a first RFID transponder coupled to the intrusion sensor; and
a first RFID reader in wireless communications with the first RFID transponder;
wherein the first RFID transponder communicates a present state of the intrusion sensor to the first RFID reader and the first RFID reader reports the present state to a first control function in the security network.

Abstract
A security network for a building using at least one RFID reader to communicate with at least one RFID transponder to provide the radio link between each of a number of openings and a control function capable of causing an alert in the event of an intrusion. A gateway provides an interface between the security network and various external networks. The control function can be located in either or both of the RFID reader and the gateway. The RFID transponder is connected to an intrusion sensor. The gateway can communicate with the RFID reader using active RF communications, power-line communications protocol, or hardwire connection. The RFID transponder can contain an energy store. The RFID reader contains means for transferring power to an RFID transponder for the purpose of charging any energy store. The security network can contain more than one RFID reader.

33. An RFID reader for use in a security network for use in a building with a first opening to be monitored for intrusion, comprising:
-
first means for communicating with an RFID transponder using wireless communications techniques, including receiving a message from said RFID transponder indicating a present state of an intrusion sensor; second means for receiving commands from a first control function and for reporting the present state of the first RFID transponder to the first control function; and a processor controlling the functions of both the first and second means and directing the message from the first means to the second means.
