Field brief
Offline-first communication model
CBBS communication model across hub services, local nodes, room clients, and transport layers.
Hub and field nodes
CBBS uses the hub as the durable coordinator, archive, scheduler, and operator surface. Field nodes participate as radio heads, relays, room servers, and local terminals.
Local access
Nearby users can connect to a room-node Wi-Fi surface and use a browser client for account access, room browsing, local board visibility, and policy views.
Transport direction
The system treats LoRa as the authoritative long-range store-and-forward path, with local Wi-Fi used for nearby presentation and access.
