sidebar_label: Multiple channels
---
Version 1.2 of the software adds support for multiple (simultaneous) channels. The idea behind this feature is that a mesh can allow multiple users/groups to be share common mesh infrastructure. Even including routing messages for others when no one except that subgroup of users has the encryption keys for their private channel.
:::note
Older Meshtastic applications that don't yet understand multi-channel support will only show the user the primary channel.
:::warning
Multiple channel support is currently an experimental feature that is ONLY supported by the Python CLI.

### What is the Primary channel
The way this works is that each node keeps a list of channels it knows about. One of those channels (normally the first one) is labelled as the "PRIMARY" channel. The primary channel is the **only** channel that is used to set radio parameters. This channel controls things like spread factor, coding rate, bandwidth etc... Indirectly this channel also is used to select the specific frequency that all members of this mesh are talking over.
