https://devzone.nordicsemi.com/f/nordic-q-a/97181/long-range-distance-measurementHello and thank you for your help. I am working on a project that uses distance measurements (DM). According to the Introduction to Nordic Distance Toolbox webinar , the largest distance tested was around 18m with a standard deviation of 37cm usingen-USTelligent Community 13Wed, 01 Mar 2023 12:59:14 GMThttps://devzone.nordicsemi.com/thread/412746?ContentTypeID=1Wed, 01 Mar 2023 12:59:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7377b18b-83cc-4ad7-b372-a51d506be511Simonr<p>Hi</p> <p>We have not done any tests with the Distance Toolbox in terms of maximum range. The deviation of distance measurements must be expected to increase with distance, as there will be more interference from more sources the further away you get. The range you&#39;ll be able to achieve and quality of the signal is mostly dependent on the environment you&#39;re deploying the devices in, and testing should be done in similar environments to get reliable test results.&nbsp;</p> <p>I personally would not expect better accuracy than 1m at 100m range in a no to low noise environment, but this is mostly educated guessing on my end. At 500m you should be able to keep a BLE connection in a low noise environment, but the distance measurement will likely not be very reliable.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
