Can I improve my LoRa-coverage simulation using Radio Mobile?

End Devices (Nodes)

Dear TTN-Fellows,

I’ve installed and played a bit around with Radio Mobile. Another user also used radio Mobile:

I would just like to ask you whether I am using the correct settings grafik

I have added two units:

  1. Gateway
  2. Node

and added both to the same system with the values suggested in the other thread, the standard ones for LoRa with 14dBm and sensitivity around -120dBm.

The plot looks quite reasonable. Do you have an idea for improvements?

Thank you!

I have some workshop papers from last year TTN conference here https://github.com/pe1mew/TTNConference_WorkshopRadioPlanning.
I hope.this is of help.

Thanks everyone, thanks in particular Arjan. I will go through the workshop papers first before posting any additional comment.

I’ve made my first steps with Radio Mobil and created some connectivity maps, where the coverage pretty much reflects the height profile of the area, which is quite reasonable. Improving the antenna height improves the coverage -> makes sense as well. The next step for me would be to assume more realistic parameters and understand more about the software. What settings do you recommend for:

  1. Surface refractivity
  2. Ground conductivity
  3. Relative ground permitivitty
  4. Mode of variability
  5. Membership: command or subordinate?
  6. Systems: what is a realistic sensitivity to assume? Is it really the -144dBm or more like -125dBm?
  7. Style: I don’t get when red, yello and green lines are drawn with respect to the 14dBm setting of the transmitter.
