xArray Reader System

Peak Performance—24/7

Autopilot technology senses, configures, adapts

Speedway readers use Autopilot, a set of unique firmware features that work together to automatically optimize the reader's operation for its environment, delivering peak performance at all times.

  • Autoset—senses levels of RF noise and interference, automatically selecting appropriate settings.
  • Low duty cycle—reduces RF interference, power consumption, and energy costs
  • Dynamic antenna switching—senses where tags are in the field and automatically focuses on antennas with the largest tag populations, improving throughput and efficiency

Hands-Free, Overhead Monitoring

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. 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. Additional features include:

  • Beam-forming 2-D array radiates linear beam pattern in vertical and horizontal paths to read tags in any orientation
  • 52 antenna beams enable assignment of locations (x,y) or zones
  • Robust tag direction capability supports real world movement patterns
  • Easy to use and maintain with IEEE 803.2af PoE, tilt sensor to detect when out of alignment, hysteresis feedback to alert when antenna may be blocked, and customizable beacon.
  • Easy programming using LLRP and Impinj extensions
