The Impinj Threshold antenna connects to an Impinj Speedway reader to provide wide zone coverage ideal for a road race course or other boundary or threshold crossing.

As part of a custom solution built with a Speedway reader, Threshold antennas identify items as they pass over or under a threshold or boundary. Its high-capacity read range is designed to maximize intensity in highly-specific zones.

This antenna has two part numbers, each designed for use in a specific region:

  • IPJ-A0311-USA (FCC)
  • IPJ-A0311-EU1 (ETSI)
