Downlink Data Reception Based on Payload and Data Rate

The following figures illustrate the downlink data reception 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 displays the settings and payload sizes to profile the payload and data rate-based downlink data reception scenarios.

Table 1. Downlink Data Reception Scenarios
Attribute	Value
TX power⁽¹⁾	1 (default)
RX1 receive window data rate	DR0 and DR5
RX2 receive window data rate	DR0
Default payload	11 bytes (temperature sensor data)
Max payload	DR0 = 43 bytes and DR5 = 234 bytes
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. Figure 1. Actual TX Power Actual TX⁢ Power⁢ = MAX⁢ EIRP⁢−2⁢ dB=16−2=14⁢ dBm
