There are different regulations all around the world, which specify how people can use LoraWAN with ISM bands in their countries. In this article we are going to explore the detailed deployment of LoraWAN in these different regions. Accoring to LoRaWAN Regional Parameters V1.0.2, Korea, Japan and the rest of countries like Thailand, Vietnam and Singapore have the similar regulations compared to US and EU.


LoraWAN regulations in India

There are three default channels in India to use, all the gateways should listen to the channels with 125kHz. They are 865.0625MHz, 865.4025MHz and 865.985Mhz

In India, we specified LoraWAN specified the following channels for India between 865-867MHz:


Channel Frequency(MHz)
0 865.0625
1 865.4025
2 865.985
3 866.0
4 866.2
5 866.4
6 866.6
7 866.8


The data rate that can be used in India are listed in the following table:


Data Rate Spreading Factor& Bandwidth
0 SF12 & BW125kHZ
1 SF11 & BW125kHZ
2 SF10 & BW125kHZ
3 SF9 & BW125kHZ
4 SF8 & BW125kHZ
5 SF7 & BW125kHZ
6 SF7 & BW250kHZ
7 GFSK: 50kbps

The maximum EIRP in India is 30dBm, the antenna gain dbi should be subtracted from the TX power downlink message。

The maximum allowed payload size is listed in the following table:
Data rate Payload (bytes)
0 59
1 59
2 59
3 123
4 230
5 230
6 230
7 230


LoraWAN regulations in Australia:

Let's take a look at Australia 915-928 MHz band, which uses similar deployment as US 902-928. The uplink channels are 64+8 as well, and the downlink channels are 8, which overlaps with the uplink channels and starts from DR4.



The output power is limited to 30dBm. When BW125 is used, the frequency hop should have minimal 20 channels to perform. The end device should change channel for every transmission.

The data rate that can be used in Australia is listed below:

Data Rate Spreading Factor& Bandwidth
0 SF10 & BW125kHZ
1 SF9 & BW125kHZ
2 SF8 & BW125kHZ
3 SF7 & BW125kHZ
4 SF8 & BW500kHZ
8 SF12 & BW500kHZ
9 SF11 & BW500kHZ
10 SF10 & BW500kHZ
11 SF9 & BW500kHZ
12 SF8 & BW500kHZ
13 SF7 & BW500kHZ

The maxiumum payload size for DR0 is limited to 19 bytes. The receive window configuration is the same as the US regulations, namly:

The RX1 window is not identical to the TX channel in this region! There is a formular to calculate the RX window channel:

RX1 channel number = TX channel number mod 8

And the data rate of the RX1 is depended on the TX data rate, take DR0 as an example: When TX is sent through DR0, the RX1 should use DR10 to receive the data. If TX is DR3 or DR4, the RX1 should both be DR13.


LoraWAN also defined the AS923, which can be used in the following countries with the specific frequencies:



Frequency(MHz) Country
923-925 Brunei
923-925 Cambodia
920-925 HongKong
923-925 Indonesia
920-925 Japan
923-925 Laos
915-928 New Zealand
920-925 Singapore
922-928 Taiwan
920-925 Thailand
920-925 Vietnam


They define two compulsory channels in these regions: 923.2 and 923.4 MHz, which can only use 1% of the duty cycle to join the network. And the rest of the channels can be distributed freely by the operators.

The output power is limited to 14dBm. Since there is 400ms time on air in these regions, the end devices can only use SF10BW125 to join the network, which is DR2.

The data rate that are allowed in these regions are:

Data Rate Spreading Factor& Bandwidth
0 SF12 & BW125kHZ
1 SF11 & BW125kHZ
2 SF10 & BW125kHZ
3 SF9 & BW125kHZ
4 SF8 & BW125kHZ
5 SF7 & BW125kHZ
6 SF7 & BW250kHZ
7 GFSK: 50kbps


There is also a channel frequency list in the join response to the end devices, which sepcifies five extra channels that the network is currently using.

The size of the maximum payload size is 59 bytes for DR0.

The uplink and downlink channels are identical while the data rate should be calculated based on the time on air (dwell time).
