The list in the LoRaWAN specs :-) In China there are two ISM band ranges implemented / documented:
- CN470 - 510
- CN779 - 787
For the latter one, I've created a new issue to track it's progress: #50.
from chirpstack-network-server.
@panyingyun were you able to do some testing with the binaries? Looking forward to the results :-)
from chirpstack-network-server.
You need to add a file here (get inspiration from the already available options) for your band and modify this in order to be able to use your new ISM band.
P.S: Obviously you will need to update your vendor in loraserver if you want to use that new ISM band :)
from chirpstack-network-server.
@yzk0281 from your previous comment I am assuming you're located in China. I appologise in advance if I'm wrong.
seems to be the problem of ‘https://ajax.googleapis.com’, can not access in China~
Based on that assumption, there is already a defined band for China in the LoraWAN standard published by LoRa Alliance, for 779-787MHz
ISM Band. (LoRaWAN 1.0 Specification. Section 7.3)
You can request your own copy of the specification from this link. And then as @ivajloip pointed out, you can start by copying one of the existing bands (probably the closest one for your ISM band) and start editing it. If you have any problems doing so, I can give you hand if I can open up some free time. 😃
If working all good, I am pretty sure @brocaar would be happy to add it the list of supporting ISM bands in the future.

@ivajloip thanks for answering~
@Mehradzie band range here in China is 470 - 478
I will appreciate that if you could give a hand with this headache problem
from chirpstack-network-server.
@yzk0281 I'm more than happy to help you out with implementing a China band. Unfortunately I'm unable to test it (which is the reason why it isn't implemented yet), but it would be great if we can work together on this.
from chirpstack-network-server.
@brocaar I can test it, I got nodes and gateways currently working on 470 -478 but connecting to loraiot
I'm so glad that you can help me with that~
If you add it to the master, I will test it as soon as possible
from chirpstack-network-server.
I've created branch named test_cn470_510
with a test implementation of the CN 470-510 ISM band. After compiling, you should be able to run loraserver
with --band CN_470_510
Looking forward to your test results!
from chirpstack-network-server.
thank you ~

Hi @brocaar could you provide 433 MHz ISM band as well for rest of the world ?
from chirpstack-network-server.
Yes, no problem. Could you please create a separate github issue for this?
And could you let me know if you're able to help out with testing (I don't
have any hardware for this band to test with).

Sure, I already have devices to test at 433 MHz. I just opened a separate github issue for this.
from chirpstack-network-server.
@yzk0281 could you please let me know if the following works for you?
- data up (node -> loraserver)
- data down (loraserver -> node)
- OTAA (over-the-air activation)
I'll merge these changes into master
as soon as I have the confirmation from you (or somebody else who is able to test this ISM band) and tag a new release :-)
from chirpstack-network-server.
@yzk0281 could you tell me your email or qq, Email: panyingyun(at)gmail.com QQ:919224283. our team also test 470~510 mode, so we can help each other
from chirpstack-network-server.
@panyingyun @yzk0281 if you want, I can provide pre-compiled binaries to test with for the 470-510 band. Just let me know!
from chirpstack-network-server.
@brocaar very thank you, please provide me 470-510 band pre-conmpiled binaries for test, thanks.
from chirpstack-network-server.
here you go! https://www.dropbox.com/sh/amul3hcxz8l1s3h/AAA_u-D-F0MuuzV73VyeXABwa?dl=0

Is there a list of ISM bands defined in different countries ? :)
I am still confused about the ISM band range in China as China in the LoraWAN standard is defined for 779-787MHz ISM Band.
from chirpstack-network-server.
"7.6 CN 470-510MHz Band" 😲
How on earth I have missed this. It's totally missing from my paper copy version. Mystery
my bad.
from chirpstack-network-server.
@brocaar CN470 - 510 pre-conmpiled binaries uplink data and activation-by-personalization (ABP) test ok. Now do not know how to test Downlink data and OTAA
from chirpstack-network-server.
One way is to send confirmed data from your end-device. If you receive the confirmation, downlink communication works. More complicated way is through pushing data to some mqtt topic. See this for more information.
from chirpstack-network-server.
@panyingyun looking forward to your downlink test results. Did you manage to get it working? Would be great if we can add this band to LoRa Server :-)
from chirpstack-network-server.
@brocaar You can add this band to LoRa Server now. We test all send or receive data OK(uplink /downlink /OTAA/ABP).
from chirpstack-network-server.
Nice! Thanks for testing :-)
from chirpstack-network-server.
This band will be included in the next release (0.12.2).
from chirpstack-network-server.
470-510 uplink is normal, downlink cannot be used, where do I need to debug
