A specification for a suite of high-level communication protocols using small, low-power digital radios based on the IEEE 802.15.4 standard for wireless personal area networks (WPANs). ZigBee is targeted at RF applications requiring a low data rate, long battery life and secure networking.
Warehouse Management System
A key component of the supply chain, intended to control the movement and storage of materials within a warehouse and process the associated transactions, including shipping, receiving, putaway and picking. Such systems also direct and optimize stock putaway based on real-time information about the status of bin utilization.
Voltage standing wave ratio
A standing wave may be formed when a wave is transmitted into one end of a transmission line and is reflected from the other end by an impedance mismatch. The Voltage standing wave ratio is the ratio of maximum to minimum voltage in a standing wave pattern. It may be stated as a ratio (VSWR) or in dB (return loss).
From 300 MHz to 3 GHz. Typically, RFID tags that operate between 866 MHz to 960 MHz. They can send information faster and farther than high- and low-frequency tags. But radio waves don’t pass through items with high water content, such as fruit, at these
Tag excitation device
A term coined by the RFID Alliance Lab to refer to a device that sends signals to the tag regardless of the make or manufacturer. TED is used to measure the response of tags scientficially.
A term used to describe distributed middleware designed by the Auto-ID Center to filter data from EPC readers and pass it on to enterprise systems. It was envisioned that Savants would reside on servers across the EPC Network and pass data to one another and act as a kind of nervous system for the network.
Radio Frequency Identification
Any method of identifying unique items using radio waves. Typically, a reader (also called an interrogator) communicates with a transponder, which holds digital information in a microchip. But there are chipless forms of RFID tags that use material to reflect back a portion of the radio waves beamed at them.
