Abstract
A system associates change in the state of an asset to an event trigger within a monitored environment. This environment includes a plurality of assets and a tag transmitter positioned on each asset and operative for transmitting a wireless RE signal based on an event trigger based on one of at least the change in state of an asset and change in location of the asset. A plurality of spaced apart access points receive an RF signal transmitted from a tag transmitter. A processor is operatively connected to the access points and collect possible candidates as assets associated with the event trigger and assigning a numerical score to each candidate to determine which asset is best associated with the event trigger.
