The Channels config options are: Index, Roles, and Settings. Channel config uses an admin message sending a `Channel` protobuf which also consists of a `ChannelSettings` protobuf.
:::info
**Channel Settings** (as described on this page) should not be confused with [LoRa Radio Settings](/docs/settings/config/lora)
[LoRa Radio Settings](/docs/settings/config/lora) contain the modem configuration (frequency settings, spreading factor, bandwidth, etc.) used for the radio. These settings are identical for all channels and can *not* be unique per channel. Radio settings are directly applied to the Primary channel from which all Secondary channels derive their radio settings.
**Channel Settings** contain information for segregating message groups, configuring optional encryption, and enabling or disabling messaging over internet gateways. These settings *are* unique and configurable per channel.
The full globally unique ID will be `name.id` where ID is base36 encoded. Assuming that the number of Meshtastic users is below 20K (true for a long time) the chance of this 64 bit random number colliding with anyone else is super low. The penalty for collision is low as well.
### Name
A short identifier (< 12 bytes) for the channel.
Empty `""` by default for all channels.
If this is left an empty string it is assumed that this channel is the `default` channel.
If you use Meshtastic for exchanging messages you don't want other people to see, `random` is the setting you should use. Selecting `default` or any of the `simple` values from the following table will use publicly known encryption keys. They're shipped with Meshtastic source code and thus, anyone can listen to messages encrypted by them. They're great for testing and public channels.
