Impinj Antenna Hub
Fixed UHF RFID Reader/Writer

The Impinj Speedway Antenna Hub provides a low-cost opportunity to drive many antennas from a single fixed RAIN RFID reader. Connect up to 32 antennas to a single Speedway R420 reader with 4 Antenna Hub's connected through the GPIO Module.

The Speedway Antenna Hub solution makes RAIN RFID monitoring applications requiring many antennas, including large contiguous read zones and smart shelves, cost-effective and easy to deploy.


  • UHF RFID fixed mount antenna expansion Hub - upto 32 Antenna's supported
  • Cost Effective
  • Simple to Scale
  • Easy to Install
  • 12 Month Return to Base Warranty
