UHF RFID WAM Wide Area Monitoring System xArray


The xArray gateway is a fixed infrastructure RFID reader system that provides always-on, wide-area monitoring of RAIN RFID tagged items within a facility or across a global supply chain. Designed for large-scale item-level applications in retail, healthcare and manufacturing, the xArray gateway provides real-time Item Intelligence events including each item's identity, location, and authenticity. When combined with the Impinj Platform, the xArray gateway gives businesses unprecedented inventory visibility, allowing them to improve their operational efficiency and provide better service to their customers. It brings proven tag direction capability to the market in a package that is both low cost and easy to deploy. The Speedway xArray system provides wide-area monitoring through its beam-forming antenna array, which delivers full power throughout a 40 foot diameter when ceiling-mounted at 15 feet high.


The xArray system can distinguish 52 different antenna beams providing for location assignment within the read zone, and the antennas radiate a linear pattern in both the horizontal and vertical paths in order to read tags in any orientation. The reader itself is optimized to read many thousands of tags very quickly, and to distinguish tags of interest from the rest of the field. The xArray can be configured to handle both wide-area monitoring scenarios and portal applications. Moreover, Impinj has added robust tag direction capability that has been proven accurate even in difficult, real world environments.


Both cost-effective and easy to deploy, the Speedway xArray system's slim profile was designed to mount easily into a single tile of a standard drop ceiling, where it is unobtrusive and able to blend into any décor. The Speedway xArray includes a tilt sensor, hysteresis feedback, and programmable beacon to alert users when the system or environment may need attention. The xArray draws minimal power (which keeps costs low) and runs from standard PoE (IEEE 802.3af), so there is no need to hire an expensive electrician for installation. Furthermore, the Speedway xArray is programmed using industry-standard LLRP and Impinj extensions, for maximum re-use of code and minimum delays due to learning curve with new APIs.
