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.
