Meshtastic Canada: Sovereign Mesh Networking for Bitcoin and Off-Grid
Quick answer
Mesh networking uses inexpensive long-range LoRa radios running open-source Meshtastic firmware to send messages — and even raw Bitcoin transactions — with no internet, cell tower, or carrier. Each node relays for the others over Canada's license-free 902–928 MHz band. D-Central mesh nodes are in development — register your interest and we'll tell you when the first builds are possible.

Sovereign mesh networking lets you send messages — and even Bitcoin transactions — with no internet, no cell tower, and no carrier, over inexpensive long-range LoRa radios running open-source Meshtastic firmware. When the ISP drops, the sovereign stack keeps communicating. This hub is D-Central’s home for Canadian Meshtastic and LoRa: how it works, what it is for, the hardware, and where D-Central’s own builds stand (in development).
What is Meshtastic?
Meshtastic is a free, open-source project that turns cheap LoRa radio modules into a self-healing mesh: each node relays messages for the others, so a chain of inexpensive devices can carry text across kilometres with no infrastructure in between. You pair a node to your phone over Bluetooth and message off-grid. Credit where it is due — Meshtastic and the broader LoRa ecosystem are community-built open source, and our work here stands on theirs. Start with our getting-started primer for Bitcoiners and the deeper LoRa protocol explainer.
LoRa frequencies in Canada
In Canada, Meshtastic runs on the 902–928 MHz ISM band — the same license-free band used in the United States, regulated by ISED. For standard low-power nodes you do not need a licence. If you add a high-gain antenna for long-range relay, keep your setup within ISED’s license-free limits (RSS-210); we will size antennas accordingly. (Orientation, not regulatory advice — confirm current rules at ised-isde.canada.ca.)
Why Bitcoiners and sovereign operators use mesh
- Connectivity that can’t be cut. Keep a node, miner, or agent reachable when the ISP or grid goes down — see Mesh Keeps Your Node Online When the ISP Drops.
- Off-grid Hashcenter comms. A redundant communications layer for remote mining and compute sites — Off-Grid Hashcenter Mesh Comms.
- Bitcoin without the internet. You can broadcast a raw Bitcoin transaction over LoRa to a relay that forwards it to the network. It genuinely works — but LoRa is low-bandwidth, so a single transaction takes tens of seconds and it is not suitable for Lightning or high-frequency payments. The honest walkthrough is in Bitcoin Over Meshtastic.
Mesh + Nostr: the decentralized comms layer
Mesh handles transport; Nostr handles identity and publishing. Together they are the communications layer of the sovereign stack — own your money (Bitcoin), your intelligence (a local LLM), your connectivity (mesh), and your identity (Nostr), and no single actor holds an off-switch over you. Start with Nostr for Bitcoiners, then run your own relay.
Hardware and pre-configured nodes
D-Central mesh hardware — hand-built nodes under Sovereign Mesh — is in development; no units are built yet. Each node is designed to arrive configured for the 902–928 MHz Canadian band and ready to join your mesh. Register your interest on the product pages and we will let you know when the first builds are possible.
Have D-Central design and deploy it
From a single home node to a multi-site community mesh, an off-grid relay on solar, or a comms overlay for a Hashcenter — that deployment work is in development: designing the network, picking and placing the nodes, and setting up the firmware. It is the same conversation as our wider sovereign-stack work.

Frequently asked questions
What is Meshtastic and what is it for?
Meshtastic is open-source firmware that turns low-cost LoRa radios into a self-healing mesh network for off-grid text messaging and telemetry. Each node relays for the others, so messages travel kilometres with no internet, cell tower, or carrier — useful for remote properties, emergency resilience, and keeping a Bitcoin node or miner reachable when the ISP drops.
Do I need a licence to run Meshtastic in Canada?
For standard low-power nodes on the 902–928 MHz ISM band, no — it is a license-free band in Canada under ISED, the same band used in the US. If you add a high-gain antenna for long-range relay, keep the setup within ISED’s license-free limits (RSS-210). This is orientation, not regulatory advice; confirm current rules with ISED.
Can I really send Bitcoin over a mesh network?
Yes. Open-source projects let you broadcast a raw Bitcoin transaction over LoRa to a relay node that forwards it to the Bitcoin network. It works for sovereignty and censorship-resistance, but LoRa is low-bandwidth — a single transaction takes tens of seconds and it is not suitable for Lightning or high-frequency payments.
How far does a Meshtastic node reach?
It depends heavily on terrain and antenna. Expect up to a few kilometres in a town and 20 km or more line-of-sight from a rooftop or hilltop with a good antenna; dense urban areas are shorter. Check the public Meshtastic community map for documented links in your area before planning a deployment.
Can D-Central set up a mesh network for me?
Not yet — mesh network design and hardware are in development, and no builds are shipping. Register your interest on the mesh product pages and we will let you know when the first deployments are possible.

The sovereign stack: own every layer
Sovereignty is layered: Bitcoin for money, a local LLM for intelligence, mesh for connectivity, Nostr for identity, and your own power. Each piece is one more layer no single actor can switch off.
