# RCBox Network Topologies
|
|||
|
|
|
|||
|
|
RCBox is a Raspberry Pi–powered micro server and Wi-Fi hotspot that serves
|
|||
|
|
static content offline and hosts secure messaging and public chat.
|
|||
|
|
|
|||
|
|
## 1. Standalone Offline — Direct Wi-Fi Clients
|
|||
|
|
|
|||
|
|
A single RCBox acts as an access point; clients associate directly to its
|
|||
|
|
Wi-Fi radio. No internet, no upstream — fully self-contained.

|||

## 2. Multiple RCBoxes on a Wired LAN
|
|||
|
|
|
|||
|
|
Several RCBoxes are joined by Ethernet and share data peer-to-peer across
|
|||
|
|
the wired backbone. Each RCBox continues to serve its own Wi-Fi clients.

## 3. RCBox with Wi-Fi HaLow Extended Range
|
|||
|
|
|
|||
|
|
An RCBox uplinks to a Wi-Fi HaLow hub router. Remote endpoints reach the
|
|||
|
|
hub via HaLow bridges — one bridging a client device, another bridging a
|
|||
|
|
second RCBox at distance.

## 4. Opportunistic Mobile Mesh
|
|||
|
|
|
|||
|
|
A stationary RCBox anchors a location. Mobile RCBoxes — one mounted in a
|
|||
|
|
bus, another on a motorcycle — carry data as they move, syncing
|
|||
|
|
opportunistically whenever they come within Wi-Fi range of the base or
|
|||
|
|
each other (a store-and-forward "sneakernet over Wi-Fi").
