In a tag communication system, a method includes determining range information representative of a distance between two tags, and estimating parameter information representative of backscatter signals of a marker tag and an asset tag. A tag is localized according to the range information and the parameter information to provide a localized tag. The range information is determined according to a beacon signal. The system includes a plurality of beacon signals and the method further includes determining the range information according to at least two of the beacon signals. A logical operation is performed on the range information of the two beacon signals. A further beacon signal has a plurality of signal ranges and the range information is determined according to the signal ranges. A logical operation is performed on the range information of the signal ranges.

Localizing tagged assets in a configurable monitoring device system

A system for radio frequency identification of a tag in an interrogation zone, includes a calibration node disposed in the interrogation zone to measure a signal strength of radio frequency identification signals from a beamforming system and provide signal data in accordance with the signal strength. A reader node is configured to receive the signal data and adjust the radio frequency identification signals generated by the beamforming system based upon the signal data. At least one of the calibration node, the reader node and the beamforming system is a configurable monitoring system. The calibration node, the reader node, and the beamforming system are coupled in a feedback control loop. The beamforming system includes a plurality of beamforming nodes. A signal of at least one beamforming node is optimized in accordance with the feedback control loop.

Calibration of beamforming nodes in a configurable monitoring device system

The invention includes a method of detecting out-of-stock conditions for retail products, and for dynamically updating associated replenishment plans, sales forecasts, and event scripts for product stocking events such as turn stock products, promotional products, new product introductions and modular resets. The invention accesses RFID data associated with product stocking events for identifying product movements in a retail supply chain and within a retail store. The invention optionally accesses point-of-sale and perpetual inventory data for detecting out-of-stock conditions. The invention also includes a method for dynamically improving product layout and optimized planograms based on out-of-stock velocity detection.
