How It Works
The Inland NW Mesh network is built on proven, open-standard hardware and firmware that anyone can deploy and maintain. Here's how it all comes together.
The Technology
Our network uses LoRa (Long Range) radio technology — a spread-spectrum modulation technique that allows small, low-power devices to communicate over distances of 1 to 15+ miles per node, depending on terrain and antenna setup.
All nodes run MeshCore, an open-source mesh networking firmware designed specifically for LoRa devices. MeshCore handles routing, encryption, and message delivery automatically — no configuration expertise required to use the network once a node is deployed.
Technical Specifications
| Parameter | Specification |
|---|---|
| Radio Technology | LoRa (Long Range) spread-spectrum modulation |
| Firmware | MeshCore — open-source mesh networking firmware |
| Frequency Band | 915 MHz ISM band (US unlicensed) |
| Frequency Range | 902 – 928 MHz |
| Transmit Power | Up to 30 dBm (1W) — configurable per node |
| Modulation | LoRa CSS (Chirp Spread Spectrum), SF7–SF12 adaptive |
| Typical Range | 1–15+ miles per node (terrain and antenna dependent) |
| Network Topology | Fully decentralized peer-to-peer mesh; no central server required |
| Encryption | AES-128 / AES-256 end-to-end encrypted; PKI-based device identity |
| Message Routing | Store-and-forward flooding with hop-count TTL; path-redundant |
| Power Options | USB-C, solar, and battery — enabling off-grid node deployment |
| Node Hardware | ESP32-based LoRa dev boards (T-Beam, T3S3, Heltec, RAK, and others) |
| Redundancy | Multi-path mesh routing; loss of any single node does not break the network |
How Messages Travel
When you send a message on the network, it doesn't go through a central server. Instead, it hops from node to node across the mesh until it reaches its destination. This is called store-and-forward flooding — if a node isn't reachable right now, a nearby node holds the message and forwards it when connectivity is restored.
This means:
- No single node failure can break the network
- Messages can travel far beyond the range of any single radio
- The network heals itself automatically as nodes come and go
Power Independence
Every node on the network can run on USB-C power, battery, or solar panels. This means nodes continue operating during power outages — exactly when you need them most. View our recommended solar node hardware for specific builds.
Security
All communication on the network is encrypted end-to-end using AES-128 or AES-256. Each device has a unique PKI-based identity, so you always know who you're talking to.
