UHF RFID Reader System/xArray Gateway

This low profile UHF xArray gateway reader provides always-on and wide-area monitoring, intelligent item locating, and updates inventory information with real-time location information, all without human intervention.


This xArray gateway is a fixed infrastructure RFID reader system that provides always-on and wide-area monitoring for real-time identification and location of RFID tagged items.

This xArray gateway is a fixed infrastructure RFID reader system that provides always-on and wide-area monitoring allowing businesses to continuously and automatically collect data about items of interest, providing updated inventory information and real-time location of individual items; all without human intervention. This xArray gateway is ideal for large-scale, item-level applications within retail, healthcare and manufacturing, it provides data that allows businesses to deliver better customer service, increase employee productivity and make better business decisions.

Key Features

  • A single xArray can monitor up to 1,500 sq. ft. (139m2) when Monza R6 based tags are used, extended coverage with multiple xArrays
