Overview

AdvanTrack is a RFID-based system that provides inventory in real time of all tagged items located in a given space. Examples of such spaces are retail stores, small warehouses, hospital areas, etc.

AdvanTrack also supplies the approximate location of each tagged item in real time.

AdvanTrack includes:

• Antennas

• Multiplexers

• Readers

• RF cables

• Control cables for multiplexers

• Power Over Ethernet injectors

• Software drivers, including a tag location algorithm

AdvanTrack comprises a set of overhead antennas, spaced approximately 1.5 m x 1.5 m.

Benefits:

• Persistent inventory

• Reduction of stock-outs

• Fast location of products

• Detection of misplaced items

• Shrinkage reduction

Applications:

• Retail stores

• Hospitals

• Low height warehouses

AdvanTrack also comprises RDIF readers and RFID multiplexers that are connected to the antennas.

Each antenna covers an area of approximately 3 metres diameter, and detects the tags located under its area of interrogation. The antennas are usually sequentially activated, obtaining the identification and position of each tagged item every few seconds.

By providing real time inventory and location, AdvanTrack can reduce stock-outs, detect misplaced items, and reduce theft. Additionally, it helps finding products much faster, which may lead to more satisfied customers and more productive employees.

The antennas have circular polarization and a radiation pattern characterized by a pencil beam shape (40°/40°).
