https://devzone.nordicsemi.com/f/nordic-q-a/41718/nb-iot-backscatteringHi, I recently dug into the potentials of the NB-IOT network allowing iot devices to directly make use of cellular communication. With the release of the new nrf9160 containing functionality to use the NB-IOT, my interest in the subject went from 0en-USTelligent Community 13Thu, 03 Jan 2019 15:19:52 GMThttps://devzone.nordicsemi.com/thread/163808?ContentTypeID=1Thu, 03 Jan 2019 15:19:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9309b1da-45ec-4302-86cc-3088e0d88c63Marjeris Romero<p>Hi,</p> <p>I am not sure I understood your question. But RFID is a near-field technology, used sometimes to track objects with a short transmission path. As far as I know, passive RFID systems (the ones using backscattering and which do not require a power source or a transmitter) have a range of typically less than 10 m. </p> <p>The use of a mobile network is needed when tracking over larger distances or when the use user needs a connection to the cloud and access via mobile devices (phone, tablet). NB-IoT is a standardized protocol specifically developed for this use case and it needs an active transmitter.</p> <p>Best Regards,</p> <p>Marjeris</p><div style="clear:both;"></div>
