At ST25RU3993-HPEV firmware how to control an antenna distance? For eg. I want an antenna to read tags in 3ft only.

    Hello YChav.3

    In general the read range can be limited with the TX power settings. The less Tx power the less read range. A strong dependency is also given through the used antenna. Also the used Tag and frequency can have a impact on the read range. This means one Tx power settings can limit the read range for one setup, but could allow to read further with a different setup.
