Abstract
A wireless tracking device may receive, from a server of a wireless tracking system, a cell tower data set having an entry with a cell tower identifier and cell tower location coordinates for each of at least one cell tower located along at least part of an expected route of an asset associated with the wireless tracking device. At intervals, the wireless tracking device activates a cellular communication circuit to receive at least one wireless signal including a broadcast cell tower identifier. The wireless tracking device retrieves cell tower location coordinates from an entry of the cell tower data set where the cell tower identifier matches the broadcast cell tower identifier. The wireless tracking device determines a location estimate of the wireless tracking device based on the retrieved cell tower coordinates.
