The duration of a pulse of energy sent to UHF EPC Gen 2 tags to indicate a 0 in binary code. EPC Gen 2-compliant readers use pulse interval encoding (PIE) to code binary data. A binary ‘0’ is indicated by a short, high-level pulse, followed by a low pulse of equal length. The length of a TARI can vary from 6.25 to 25 microseconds.
