Impinj xArray Gateway RFID Reader



Impinj xArray Gateway RFID Reader

The Impinj xArray is a fixed infrastructure RFID gateway that integrates a RFID reader with antennas to provide always-on, wide-area monitoring for real-time identification, location, and direction of RFID tagged items. The xArray 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 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. This device 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 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 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 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.

Why buy this reader?

Designed for large-scale item-level applications in retail, healthcare and manufacturing, the Impinj xArray Gateway RFID Reader delivers wide-area monitoring, locationing and tag direction capabilities of RFID tagged items within a facility or across a global supply chain.


  • Operating modes: inventory, tag direction, and location.
  • Can achieve throughput of about 1,000 tags per second.
  • Easy programming using Octane SDK, LLRP and Impinj extensions.
  • Low profile design fits into standard ceiling tile grid and blends into décor.
  • Intelligent item locating with 5 ft. (1.5 m) or better spatial resolution of (x,y) location.
  • Exceptional performance provided by 2-D array with 52 dual-polarized antenna beams.
  • Easy to use and maintain with IEEE 803.2af PoE, tilt sensor to detect when out of alignment.
  • Location accuracy: 85% within 5 ft. (1.5 m) in ideal conditions; 66% within 3.3 ft. (1 m) in ideal conditions.
  • A single xArray can monitor up to 1,500 sq. ft. when Monza R6 based tags are used, extend coverage with multiple xArrays.
  • Patented Autopilot functionality automatically optimizes the xArray for its environment, ensuring peak performance at all times.
  • Unique functionality with defined operating modes: wide-area monitoring for tracking overall tag inventory; locationing for obtaining tag x,y location; and tag direction for tracking tags moving through sectors.
  • Common applications: retail physical inventory accuracy and visibility, retail loss prevention, retail automation, asset tracking and RTLS, safety and security, personal experience, and traffic flow such as amusement parks or entertainment venues.
