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