Speedway® Reader's Tag Direction Feature

Impinj's Speedway reader Octane 3.0 firmware includes an innovative new feature—the ability to determine a tag's direction of travel without expensive, special-purpose hardware. Using any conforming UHF Gen 2 tag, off-the-shelf reader antennas, and our Speedway reader, Impinj's proprietary tag directionality capability reports results in less than a second via an LLRP (low level reader protocol) response message—without having prior knowledge of particular EPC tag types, and even when multiple items are moving in opposite directions through the antenna field.

Tag directionality promises to increase the reliability of system data. Reporting a tag’s direction of travel back to the controlling application provides useful information in a variety of situations. This demonstration video shows our tag direction algorithm in action.
