https://devzone.nordicsemi.com/f/nordic-q-a/92554/lte-m-coverage-free-sightHi According to your Blog &quot;LTE-M vs NB-IoT Field Test: How Distance Affects Power Consumption&quot; the maximum distance between the base station and the Dev-Kit was 12km. Do you know: - The maximum distance for nRF9160 in free sight (e.g out at sea)?en-USTelligent Community 13Mon, 10 Oct 2022 12:44:44 GMThttps://devzone.nordicsemi.com/thread/390016?ContentTypeID=1Mon, 10 Oct 2022 12:44:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:40334e83-c0d6-454c-8dfa-2700d646121fMichal<p>Hello,</p> <p>Unfortunately, I don&#39;t think that we have any more extensive test than the one that you have seen already.</p> <blockquote> <p>The limiting factor for achieving longer distances using nRF9160?</p> </blockquote> <p>The limiting factors are probably signal power and antennas.</p> <blockquote> <p>The maximum theoretical distance for LTE-M?</p> </blockquote> <p>I found a nice paper <a href="https://hal.archives-ouvertes.fr/hal-01451229/document">Samir Dawaliby, Abbas Bradai, Yannis Pousset.
