A decentralized, public, off-grid communication network based on radio mesh technology. Join the pilot project and help expand the network.
About the Project
Connecting Florianópolis in a free and decentralized way
Connecting Florianópolis in a free and decentralized way
The MeshOffGrid.Net project aims to create an alternative communication network that works independently of the traditional internet.
What is a mesh network?
What is a mesh network?
A mesh network is a topology where each node not only uses the network, but also acts as a repeater, extending the total range. This allows for the creation of a resilient and self-organizing communication mesh.
Why off-grid?
Why off-grid?
Off-grid networks operate without relying on conventional internet or centralized infrastructure. This ensures communication even in disaster situations, access blocks or in remote locations.
Our pilot in Florianópolis
Our pilot in Florianópolis
We started with 5 strategically positioned nodes in Florianópolis, allowing initial coverage in key areas of the city. Each new node installed expands the reach and capacity of the network. We are using the Meshtastic.org project to implement this network because it is widely used worldwide and provides extensive documentation for enthusiasts of this technology.

Mesh network topology
Mesh network topology
Unlike traditional networks with central points of failure, in a mesh network each node connects to multiple other nodes, creating redundant routes for communication. If one node fails or is unavailable, data simply follows another path.
Radio broadcast
Radio broadcast
We use long-range radio transmitters that operate on free frequencies. Each node can communicate directly with other nodes within a radius of several kilometers, depending on topography and other environmental factors.
Dynamic routing
Dynamic routing
The system uses dynamic routing protocols that automatically discover the most efficient paths for messages, constantly adapting to changes in the network as new nodes are added or removed.

Why build an off-grid mesh network?
Why build an off-grid mesh network?
The MeshOffGrid network offers unique benefits to individuals and communities.
Resilience and Redundancy
Resilience and Redundancy
With no central points of failure, the network continues to function even if some nodes become unavailable. Ideal for emergencies and natural disasters.
Privacy and Independence
Privacy and Independence
Communication free from corporate or government surveillance. Data travels directly between users without centralized intermediaries.
Organic Expansion
Organic Expansion
Each new node expands the reach of the network. The community collectively builds a communication infrastructure that grows organically.
Low Cost
Low Cost
Affordable components and open technology make deployment economically viable, at a much lower cost than commercial networks.
Reduced Energy Consumption
Reduced Energy Consumption
Low-power LoRa technology allows nodes to operate on batteries or small solar panels, ideal for remote areas or those with limited infrastructure.
