1. A method for monitoring an area, the method comprising:
- disposing a plurality of nodes about the area to be monitored, each of the plurality of nodes configured to produce an electromagnetic field in the area;
forming a wireless network among the plurality of nodes;
configuring each of the plurality of nodes to transmit data;
configuring each of the plurality of nodes to receive data frames with a signal strength indicator and a link quality indicator; and
analyzing variations in the signal strength indicator and link quality indicator to detect disturbances to the electromagnetic field in the area.

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.

8. A method for monitoring an area, the method comprising:
-
forming a wireless network among a plurality of nodes with each of the nodes configured to produce an electromagnetic field in the area and wherein the electromagnetic field produced by each node has a strength sufficient such that it can be detected by at least one other of the plurality of nodes; configuring each of the plurality of nodes to transmit data and receive data frames with at least some of the frames having a signal strength indicator and a link quality indicator which provide information about the electromagnetic field; and detecting and tracking disturbances to the electromagnetic field by analyzing variations in the signal strength indicator and link quality indicator. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
