Application Note - Low Level User Data Support


Download Application NoteDownload File


This application note provides the operator of a Speedway Revolution reader with the necessary information to utilize the Radio Frequency (RF) phase and Received Signal Strength Indication (RSSI) low level user data.

The target audience is any party interested in using the RF phase and RSSI reporting features. Note that the low level user data feature requires a Speedway Revolution reader with at least Octane 4.4 firmware to receive any low level tag metrics, however the latest optimizations to these tag reports, including the Doppler effects described here, are available beginning with Octane 4.8.
