Wireless asset monitoring system and method having designations of logical place
First Claim
1. A system for wirelessly monitoring assets using a multi-hop communications network comprising:
- a plurality of networked communications nodes for transmitting a beaconing radio frequency (RF) signal from at least one network node;
at least one asset node for receiving the beaconing RF signal; and
wherein the at least one asset node determines if it is in an authorized location based upon logical place information received from the at least one network node.

Abstract
A system for wirelessly monitoring assets using a multi-hop communications network (10) includes a group of networked communications nodes for transmitting a beaconing radio frequency (RF) signal from a group of network nodes (11, 13, 15). One or more asset nodes (17, 19) are used for receiving the beaconing RF signal where the asset nodes (17, 19) determine if the asset is in an authorized location based upon logical place information received from the at least one network node. Logical place information includes an informal location name without the use of positional location coordinates. The invention is advantageous since it enables the asset to determine whether it is in an allowed, forbidden or disallowed location without the burden of calculating its physical position.

6. A method for wirelessly monitoring assets including the steps of:
-
forming a network using a plurality of network nodes and at least one asset node;
receiving logical place information at the at least one asset node from at least one of the plurality of network nodes; and
determining a status condition from the logical place information and transmitting the status condition regarding the at least one asset'"'"'s location to at least one of the plurality of network nodes if the at least one asset is in an allowed, forbidden or lost location. - View Dependent Claims (7, 8, 9, 10, 11, 12)
