1. A wireless locating network, comprising:
- a tag containing data;
a reader to read the data from the tag;
at least one network mote, the mote having a wireless mesh network receiver/transmitter, a wireless mesh network data modulator, a CPU, and memory; and
,a host computer, wherein the host computer is adapted to track the location of the tag within the wireless network via communication between said tag, said reader, said communication mote and said host computer.

Abstract
A wireless location system is provided. The system includes network tags that emit a signal containing tag data, network readers that continuously receive data from the tags, a communication motes to receive the tag data from the readers and to calculate a network signal strength of the signal between the reader and the mote, and a server. The server receives the tag data and network signal strength data from the communication mote, performs calculations on the data, and determines the location of the reader that received the tag data based in part on the received network signal strength data.

16. A wireless location system, comprising:
-
a plurality of network tags, each tag having independent tag data and each tag emitting a signal containing the tag data; a plurality of network readers to continuously receive data from tags within a certain range of the reader, the readers further transmitting the received tag data; a plurality of communication motes to receive the tag data from the readers, the communication motes calculating the network signal strength of the signal between the reader and the mote; and
,a server to receive the tag data and network signal strength data from the communication mote, wherein the server also performs calculations on the data and determines the location of the reader that received the tag data based in part on the received network signal strength data. - View Dependent Claims (17)

20. A wireless location system, comprising:
-
a plurality of node beacons adapted to be fixed to movable objects, the node beacons sending a signal contain data related to the object to which it is fixed; a communication mote having a receiver/transmitter, wherein the mote receives the signal from the beacon and buffers the data in its internal memory, and wherein the mote also performs a network signal calculation; and
,a host server resident on a secondary network, wherein the host server receives data from the communication mote related to the network signal calculation and the signal the mote received from the beacon, identifies the object having the node beacon, processes the data and tracks the location of each beacon, and stores the data in a database resident in the host server.
