Max range and performance within limitations

[LoRaTracker]

@Jakub_Nagy

Let’s say I have an airtime of 1812ms on SF12 and an airtime of 452ms on SF10. How much smaller should I expect the range to be? 30%? 40%? 50%? I know that’s impossible to predict precisely, I just want an estimate.

Use Semtechs LoRa calculator.

The relative sensitivity difference between SF12 and SF10 is 5dB, so SF12 should go approximatly 78% further.
