An inventory control and management method provides a combination mobile device for communication and for reading labels (R&C). The R&C reads an inventory label affixed to an item of inventory in the stores. A data file is created corresponding to the label reading and includes a time stamp taken at the time of the reading. The data file is imported into a computer data processor. A network of fixed distributed communication nodes (transceivers) is positioned over the inventory store for receiving temporal cyclic signature pulses from the R&C. At least three of the communication nodes are used to perform a triangulation for locating the R&C, and the location and the corresponding time is recorded. By comparing the time of a given reading of the label with a corresponding time of the triangulation, it is possible to determine where any item is located within the stores.
