https://devzone.nordicsemi.com/f/nordic-q-a/117639/rssi-signal-variation-with-distanceHello everyone, how are you? I &#39;m doing some communication tests between nRF52840 boards. I measure RSSI at different distances. The problem is that in my tests, the RSSI got worse when I varied from 1 meter to 5 meters, 10 meters and 15 meters, allen-USTelligent Community 13Tue, 07 Jan 2025 12:27:14 GMThttps://devzone.nordicsemi.com/thread/517209?ContentTypeID=1Tue, 07 Jan 2025 12:27:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f9dc7aae-942d-4086-9f75-0a864e240632JONATHAN LL<p>Hi,&nbsp;<br /><br />RSSI is not the best tool to measure distance as it will be effected by other things so location and circumstance can give samme RSSI value at different distances.&nbsp;<br /><br />I dont know how it is in you setup but it might be that the 20+ meters away you are at a higer point further from ground\floor. This can be a explanation to why the results starts to improve.&nbsp; There might also be thigs like reflections of other surfaces or maybe there is a area where there is a lot of interference that disrupts the signal quality, moving away from that area can then give better RSSI values even if the distance is further away.&nbsp;<br /><br />Other factors can also be orientation of the antenna\device, the radiated field can be a lot better in one or two directions for example.&nbsp;<br /><br />Regards,<br />Jonathan</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/516532?ContentTypeID=1Mon, 30 Dec 2024 19:20:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ef91ea44-626c-4ce4-8867-f172d9fc0021Higo<p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1735586332667v1.png" alt=" " />&nbsp;</p><div style="clear:both;"></div>
