LoRa Modulation Connection Type

This section captures the power profile of the WLR089 device under LoRa connection type communication and highlights the profile on the following scenarios:

Data Transmission
Data Reception

Note: Use the radio level commands to set the attributes to profile the scenarios, available in the WLR089U0 radio utility firmware (Radio Utility>Radio Utility WLR089 Ver 2.00).

The following table provides the radio attribute settings considered to profile the data transmission and data reception scenarios under the LoRa modulation connection type.

Table 1. Radio Attribute Settings to Profile the Data Transmission and Data Reception
Attribute	Setting Value	Command Used
Modulation	LoRa (default)	`radio set mod lora`
Frequency	868100000 (default)	`radio set freq 868100000`
Spreading factor	SF7 (default)	`radio set sf sf7`
Preamble length	8 (default)	`radio set prlen 8`
Coding rate	4/5 (default)	`radio set cr 4/5`
afcbw	41.7 (default)	`radio set afcbw 41.7`
CRC	on (default)	`radio set crc on`
Rxbw	25 (default)	`radio set rxbw 25`
IQI	off (default)	`radio set iqi off`
PA BOOST (pa)	off (default)	`radio set pa off`
Sync	34 (default)	`radio set sync 34`
Bandwidth (bw)	125 kHz (data transmission scenario and data reception scenario 1) default	`radio set bw 125`
Bandwidth (bw)	250 kHz (data reception scenario 2)	`radio set bw 250`
TX power (pwr)	1 (data reception scenario 1 and data reception scenario 2) default	`radio set pwr 1`
TX power (pwr)	15 (data transmission scenario)	`radio set pwr 15`

Note: When PA Boost is turned off, the actual output power for the TX power setting considered for transmission and reception scenarios are as follows.

Table 2. TX Power Setting for Transmission and Reception Scenarios
TX Power Setting	Output Power (dBm)
1	-0.6
15	14.1

For more details on the actual output power to the TX power setting value, refer to the SAM R34/R35 and WLR089U0 Radio Utility Commands Reference Manual (DS70005376).
