Screenshot of the Multitech Tester Display:



 ID2: ID number (2) of the test

 DR2: Data rate (2) of the last message

 P14: Power of the last transmission, 14dBm, this is the maximum you can use in Europe

 Up Margin 0: this value describe device->gateway direction transmission

 DWN -121 db -12.2: these values describe gateway->device direction transmission


-121 is the RSSI value, what it means is the receive level on device side. minimum value is somewhere around -135 dBm

-12.2 is the SNR value, and what it means is the ratio between the signal and the noise. minimum value is around -20 dB


✔ You can change DR (data rate) and P (power) by hitting SW1

✔ We recommend to do testing when P is 14 and DR is 0 or 5, as it will cover most use-cases with these settings.

✔ The survey was successful when you see some values on the screen.


If you want to know how good the coverage is then you look for RSSI (which is the first value after DWN), bigger is better here.


  Survey sweep mode will do 28 tests and change automatically DR and P values.


With radio, 100% success is never guaranteed even when the gateway is within 1 metre. We recommend to do multiple measurements from one spot, over a period of time, to check when there is connectivity or not.
