Impinj Speedway IMPINJ R420

Impinj Speedway IMPINJ R420

The Speedway Revolution R420 UHF RFID Reader delivers the performance, quality, and reliability necessary for maximum visibility of tagged inventory and assets. Able to maintain high read rates regardless of RF noise or interference as the readers adapt automatically for optimal functionality, Speedway readers are a powerful piece of item visibility platform solutions. Impinj’s innovative Speedway® Revolution RFID reader with Autopilot automatically optimizes its operation to the environment—delivering peak performance at all times. The Speedway Revolution reader improves upon the legacy of the original, EPC-certified Speedway reader that was the first high-performance reader designed from the ground up (not merely upgraded) to support the EPCglobal UHF Gen 2 standard in its entirety. The Speedway R420 reader is supported by a suite of software, hardware, and antennas that deliver application and deployment flexibility, making installation and expansion easier than ever.


  • Autopilot — a set of unique firmware features work together to automatically optimize the reader’s operation for its environment.
  • Autoset — continuously optimizes the reader’s configuration for the best, most reliable performance.
  • Low duty cycle — reduces RF interference, power consumption, and energy costs.
  • Dynamic antenna switching — improves throughput and helps the reader work more efficiently.
  • Power over Ethernet (PoE) — simplifies deployment and dramatically reduces cost by eliminating the need for AC outlet installation at read points.
  • Improves upon the advanced hardware capabilities that made the original Speedway the reader of choice for many demanding customers—capabilities such as best receive sensitivity, interference rejection, and item-level carrier cancellation.
  • 4 Antenna Ports – Expandable to 32 antennas with Impinj Speedway Antenna Hub to deliver low total cost of ownership and greater application flexibility.
  • The industry’s highest RF sensitivity (-84dBm) provides greater accuracy and longer read ranges.
  • Field-proven, enterprise-class durability with high mean-time between failure.
