How can you get the longest distance or highest bit rate with LoRa®?

Based on what you want to achieve, longer distance or higher bit rate, there are multiple settings you can change in order to modify the parameters of communication.

Parameters for mac tx settings according to the "RN2483 LoRa Technology Module Command Reference User’s Guide":

  1. Changing TX output power : mac set pwridx <setting> - Section 2.4.8.7.
    • E.g. The command mac set pwridx 5 would set the signal strength to the minimum
  2. Changing data rate : mac set dr - Section 2.4.8.8.

Take note that the selection of the data rate is a trade-off between communication range and message duration. A lower-end data rate will offer longer range.
