3.1.3.1 Uplink Data Transmission Based on Data Rate and Payload

The following figures illustrate the uplink data transmission based on the combination of payload size and data rate.

Note: Consider using the unconfirmed packet type as the results are the same for confirmed and unconfirmed packet types.

The following table provides the settings and payload sizes considered to profile the payload and data rate-based uplink data transmission scenarios.

Note:
  1. The TX power from the preceding table resembles the offset value from the TX power table as per the RP2-1.0.2 LoRaWAN® Regional Parameters. Calculate the actual TX power value at the radio level for the above offset value using the following equation:
