I have a pair of HopeRF LoRa RFM98 Radio Modems(based on Semtech SX1278) and I want to configure them for the longest range possible, without taking care about any second factor like transmission time and power consumption.
I made already some research until I found Semtech's official tool 'LoRa Modem Calculator Tool'. The problem is I am a beginner in the hobby of radios and the tool is just confusing for me with all the various settings.
Does the tool show me all relevant configurations to achieve the longest range with my RFM? How I have to choose the settings to achieve the longest range. Any other factor is not important.
