Described is a system and method for tracking an asset. The system may
include an RF tag coupled to the asset; a wireless wide area network ("WWAN") including
a plurality of transceivers and having a first coverage area; and a plurality of
wireless local area networks ("WLAN"). Each of the WLANs has a second coverage
area within the first coverage area. In addition, the system includes a computer
which communicates with the WWAN and the WLANs. The computer generates a signal
to be transmitted to the asset using a first transceiver of the WWAN. The asset
receives the signal and generates a response signal; the asset transmits the response
signal to a particular WLAN within which second coverage area the asset is located
via a plurality of second transceivers. The computer determines the location of
the asset within the second coverage area as a function of the response signal.
