Impinj Speedway® Revolution RFID Reader Featured

RFID Reader

Application environments are dynamic. Everything from RF interference, tag quantity, and ambient RF noise to building materials near an RFID installation affect system performance.

Most users configure their RFID readers for worst case scenarios, often compromising best performance in the process.With its innovative Autopilot features, Impinj's Speedway® Revolution RFID reader delivers peak performance—all day, every day.

With Autopilot, a set of unique firmware features work together to automatically optimize the RFID 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

Impinj Speedway Revolution RFID reader also delivers increased application flexibility via support for Power over Ethernet (PoE), which simplifies deployment and dramatically reduces cost by eliminating the need for AC outlet installation at read points. 

And this revolutionary RFID reader 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.  

Impinj, defining the future of RFID, where superior performance comes easy.
