A YouTuber has shown that a private internet does not always need a telecom giant to look large or expensive. In a demonstration by Data Slayer, a cross-border mesh network linked devices in Florida and Venezuela using low-cost radio boards, Raspberry Pi units, and the Reticulum Network Stack.
The project matters because it shows a different model of connectivity. Public internet infrastructure still carries some of the traffic, but in this setup it acts more like a blind transport layer, while the actual data stays inside an encrypted private network.
A private network built from off-the-shelf parts
Data Slayer’s build uses hardware that sits well below the price range of traditional carrier-grade equipment. According to Notebookcheck’s reporting, the Heltec radio boards used in the project typically cost about $20 to $30 each, making them an unusually accessible entry point for independent networking.
That low cost changes the frame of the discussion. Instead of treating private networking as a luxury reserved for labs or enterprise users, the experiment shows that hobbyists can assemble serious communication tools with consumer-grade components.
How Reticulum changes the routing model
At the center of the project is Reticulum Network Stack, or RNS. The system is designed to move data across multiple transport layers without depending on a single protocol or a single physical path.
Notebookcheck describes Reticulum as protocol-agnostic, which means it can work over radio, Ethernet, and other carriers if they can move packets. That flexibility lets the same message travel through different kinds of infrastructure without exposing the full content to the carrier.
The setup used Android and Linux desktop devices running apps such as Mesh Chat and Sideband. This matters because it shows the network can support ordinary user devices rather than requiring specialized telecom hardware.
Why the public internet becomes only a carrier
The most unusual part of the experiment is the way long-distance links are handled. For the Florida-to-Venezuela connection, Data Slayer reportedly used Tailscale as an encrypted tunnel, while Reticulum treated that tunnel like any other transport path.
That architecture changes the role of the ISP. The provider may move encrypted packets across the physical internet, but it does not control the private network’s message layer or read the traffic inside it.
In practical terms, the ISP becomes a pipe, not the operator of the communication system. The value of the experiment lies in showing that a private overlay can sit on top of public infrastructure while remaining logically separate from it.
LoRa and Wi-Fi HaLow in the field
The network also tested different radio technologies for local connectivity. Wi‑Fi HaLow was used first, and it worked well for short-range scenarios where sub-GHz signals could pass through obstacles such as concrete walls.
For wider coverage, the project shifted to LoRa. Both Wi‑Fi HaLow and LoRa are low-power sub-GHz technologies, but LoRa was a better fit for longer links in this experiment.
Notebookcheck reported that one LoRa node maintained stable ping at more than 3 miles, or around 4.8 kilometers, with a clear line of sight. That figure is not a guarantee for every environment, since terrain and antenna height matter a great deal, but it shows the range potential of community-built mesh systems.
Key components used in the setup
| Component | Function |
|---|---|
| Raspberry Pi | Runs network services and coordination tasks |
| Heltec radio board | Provides sub-GHz wireless connectivity |
| LoRa | Extends local node-to-node range |
| Wi‑Fi HaLow | Supports short-range sub-GHz wireless tests |
| Tailscale | Creates an encrypted tunnel between distant locations |
| Reticulum | Unifies different transport paths into one mesh |
| Mesh Chat / Sideband | Enables user messaging over the network |
The combination of these parts shows that private communications do not need proprietary systems to function. They only need a layered design that can route around the limits of a single transport method.
Scale, limits, and what the experiment really proves
The reported distance between the farthest points reached nearly 2,500 miles, or about 4,000 kilometers, between Florida and Venezuela. That span did not come from long-distance radio alone, but from a mix of local radio nodes and encrypted tunneling across the public internet.
That distinction is important because the project is not a replacement for commercial internet service. It is better understood as a decentralized communications architecture that can survive beyond one provider, one protocol, or one physical route.
The experiment also highlights real-world constraints. Radio links still depend on line of sight, altitude, and obstacles, which is why drone and kite lifts were reportedly used to raise nodes to better positions.
Even with those limits, the project points to a growing shift in networking culture. As privacy concerns, resilience, and decentralization remain central topics, experiments like Data Slayer’s show that a global private mesh can be assembled from cheap hardware, open software, and encrypted tunnels.
