LoRaWAN Data Rates

written on Friday, June 23, 2017 by

While LoRa allows you to manually set transmission parameters like TX power and spreading factor, LoRaWAN uses an abstraction on top of those parameters called "data rate". The data rate, an integer value between 0 and 15, influences modulation (LoRa or FSK), the spreading factor and the bandwidth.

Since it was a bit hard to find those data rate tables through Google / DuckDuckGo, I'll list them here:

EU / CN

Frequencies:

  • EU 863-870 MHz (LoRaWAN Specification (2015), Page 35, Table 14)
  • CN 779-787 MHz (LoRaWAN Specification (2015), Page 44, Table 25)
  • EU 433 MHz (LoRaWAN Specification (2015), Page 48, Table 31)
DataRate Modulation SF BW bit/s
0 LoRa 12 125 250
1 LoRa 11 125 440
2 LoRa 10 125 980
3 LoRa 9 125 1'760
4 LoRa 8 125 3'125
5 LoRa 7 125 5'470
6 LoRa 7 250 11'000
7 FSK 50 kbps     50'000

Data rates 8-15 are reserved.

US

Frequencies:

  • US 902-928 MHz (LoRaWAN Specification (2015), Page 40, Table 18)
DataRate Modulation SF BW bit/s
0 LoRa 10 125 980
1 LoRa 9 125 1'760
2 LoRa 8 125 3'125
3 LoRa 7 125 5'470
4 LoRa 8 500 12'500
8 LoRa 12 500 980
9 LoRa 11 500 1'760
10 LoRa 10 500 3'900
11 LoRa 9 500 7'000
12 LoRa 8 500 12'500
13 LoRa 7 500 21'900

Data rates 5-7 and 14-15 are reserved.

Flattr this!
