Initially designed for boundary/threshold crossing applications, the Impinj Threshold has a very wide beam width to maximize zone coverage. Threshold antennas provide a consistent and continuous read zone when linearly distributed head-to-tail. At 18.1 x 3.5 x 0.7 inch, the Threshold's planar form factor fits readily onto fencing or other borders.
