INTRUSION DETECTION AND TRACKING SYSTEM
First Claim
1. An intrusion detection and tracking system comprising:
- a plurality of nodes disposed about an area to be monitored, said plurality of nodes forming a wireless network and configured to transmit data and receive data frames with a signal strength indicator and a link quality indicator in the frames;
a data processor (DP) communicatively connected to the network and configured to analyze variations in the signal strength indicator and/or link quality indicator to detect and track disturbances to an electromagnetic field in the area; and
a gateway configured to form a data link between the network and the DP.

Abstract
An intrusion detection and tracking system includes a plurality of nodes, a DP and a gateway. The nodes are disposed about an area and form a wireless network to be monitored, the nodes are configured to receive data and transmit data frames with a signal strength indicator and/or a link quality indicator in the frames. The DP is communicatively connected to the network and configured to analyze variations in the signal strength indicator and/or link quality indicator to detect and track disturbances to an electromagnetic field in the area. The gateway is configured to form a data link between the network and the DP.

12. A system for detecting and tracking an object in an area, the system comprising:
-
a plurality of nodes disposed about the area and establishing a wireless network and an electromagnetic field in the area, each of said plurality of the nodes configured to transmit data and receive a data with at least one other node and wherein at least some of the data includes a signal strength indicator and a link quality indicator and wherein each node monitors changes in at least one of the signal strength indicator and the link quality indicator from one transmission to another and uses such changes to detect the object; and a data processor communicatively coupled to the wireless network and configured to receive and analyze information provided thereto from at least some of said plurality of nodes. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
