How to Config a network server to support multiple regional bands concurrently

I want find a solution to setup a network server to support multiple regional regional bands concurrently in one computer server. The Keyword “name” in section “[]” in network server configure file support to config only one regional band. For example, I need to run AS923, KR920 and IN865 at the same time, but I only have one computer server, is there a solution to realize it?

You can only support one region at a time in the network server. However, you can run many network servers attached to the same (or multiple) application servers. If you’re using the containerized versions, you can easily run as many network servers on the same host as you want.

Just remember to separate the MQTT topics so you don’t get overlapping traffic between NSes.


Hi @bconway

What’s the problem to have an overlapping ?
Asking because I’m working on a implementation that should have only one UDP port to serve all gateways, including different frequencies.

This leads me to the issue that I can’t really route the traffic through MQTT topic.

Then I was jut wondering, one gateway and one device would exists only in one NS, what is the problem to other NS instance (frequency) to receive the packets from the unknown GW / Device ?

I did some tests and seems that the ALL NSes that are receiving the packets are responding to it (like join accept, etc). Just can’t understand why it is happening.

Any help on that ?

Just to let you know, I’m working on a refactor (not yet public) that should make it a lot easier to deal with multiple regions :slight_smile:


Hi Brocaar,

Would this refactor just be for different regions or would it also help for using different sub-bands within the same region, but on different gateway deployments, similar to this topic


Yes, the refactor will allow you to run multiple regions concurrently. It also allows you to run multiple configurations of the same region (e.g. US915 channels 0 - 7 and US915 channels 8-15).


Hello, What is the update about this ?

With Helium, global network, managing different chirpstack gateways witha single source looks confusing.

I did not find a documentation aout this yet.

Multi-region support is supported by ChirpStack v4 out of the box, and the chirpstack-docker repo includes a sample configuration that works for as many regions as you would like.

Yes it is multi-region but not device moving across region. A tracker as an exemple is moving from a region to another and basically the mqtt topic gets the zone, so the LNS could respond according to the right zone and don’t have a device profile associated to a given region.

What regions and frequencies are you trying to move between?

any region, EU868 to US915 then AU915 …
