Creating a Cluster

A Blackout Comms Private Cluster at its core, is really just a root device, several keys, and zero or more additional devices that have been identified as "trusted devices" by the root.

When initializing a new communicator, you will be asked if it will be a root device or standard. If you choose Root, you'll automatically create a new cluster.

A Cluster is permanently owned by the root that created it.

When you create a new cluster...

Your device generates 4 symmetric keys that will be privately shared with the cluster (during onboarding)

Your device establishes and saves the new cluster settings, marking itself as the root device going forward

Your cluster is now ready to onboard new devices

Cluster: One root device and up to 89 trusted devices

Cluster Settings

Currently, most cluster settings cannot change after they are first set. This is mainly because many devices may never come back into contact with the root device after onboarding. New devices can be onboarded and trusted, but most other cluster settings are locked in.

Choose Private

To run your own private cluster, choose Private.

Name Your Cluster

Give your cluster a name. This is similar to a WiFi SSID. You may want to use your last name, city, or whatever makes sense to you.

In the USA, use the defaults for everything else

If you don't want to use the defaults, these are the remaining settings...

Which RF Zone?

In the USA, choose the default (915.0). In other locations, check your laws.

Center Frequency

Choosing an off-center center frequency might help you avoid interference from other devices. Typically, the default is OK.

Number of Channels

Select the number of channels for your cluster. Unless you have antennas that are very finely tuned to a specific frequency, leave the default.
