Radio frequency location determination system and method with wireless mesh sensor networks
First Claim
1. A method for determining the location of a wireless node in a wireless mesh sensor network, the network comprising a plurality of wireless nodes linked to a digital computer via a communications link, the wireless nodes being wireless terminals, the method comprising:
- deploying a plurality of identifier wireless nodes each at a predetermined location;
generating node-to-node data for the wireless nodes, the node-to-node data providing information regarding a wireless node'"'"'s communication with other wireless nodes;
transmitting the node-to-node data to the digital computer;
processing the node-to-node data;
generating a map of the wireless nodes identifying the locations of the wireless nodes.

Abstract
A radio frequency (RF) system and method for determining the location of a wireless node in a wireless mesh sensor network is disclosed. The wireless node can be a wireless terminal, a wireless transceiver, or a wireless transmitter. The wireless network includes a plurality of wireless nodes linked to a digital computer, such as, for example, a server or a location processor, via a communications link. The method comprises deploying a plurality of identifier wireless nodes each at a predetermined location. Node-to-node data for the wireless nodes are generated, the node-to-done data providing information regarding a wireless node'"'"'s communication with other wireless nodes. The node-to-node data is transmitted to the digital computer where the node-to-node data is processed to generate a map identifying the locations of the wireless nodes.
