OFF-GRID
COMMUNICATION
FOR AUSTRIA

Imagine sending a message to someone standing on another mountain 30 km away. Your small LoRa device can maybe reach 10 km directly — but there is a peak in between. No problem: Your message is automatically forwarded from repeater to repeater until it arrives.

This is the MeshCore principle: There are two roles in the network — Clients (your device that sends and receives) and Repeaters (stations that forward messages). Only repeaters route packets — this saves energy on clients and makes the network efficient.

The more repeaters are set up — on mountain peaks, rooftops, observation towers — the denser and more reliable the network becomes. There is no central server, no single point of failure. If a repeater goes down, packets automatically find another route.

Bottom line: You don't need a cell tower, no provider, no internet. Clients send, repeaters forward — and together a decentralized communication network emerges.

Every message you send via MeshCore is AES-256 encrypted — the same standard used by banks and intelligence agencies. Anyone intercepting your radio packets with an SDR receiver sees only digital noise.

The key feature: Encryption happens end-to-end, directly on your device. Even the repeaters in between cannot read the content — they only forward encrypted packets, like a sealed letter.

You can set up private channels where only invited participants can read along. Perfect for groups, clubs, or emergency services. Key exchange works via QR codes or pairing links — no complicated setup needed.

Bottom line: Your communication belongs to you. No provider that can read along. No cloud that could be hacked. Just mathematics between you and the other party.

Your MeshCore node is a small board without a display? No problem. The MeshCore Companion App connects via Bluetooth to your node and becomes the command center in your pocket.

You see all messages, can send texts, share your GPS position and track other nodes on a map. Battery level, signal strength, temperature — all telemetry data collected by your node is neatly displayed in the app.

The native app is available for Android and iOS. There are also browser-based web apps that communicate directly with the node via WebSerial or WebBluetooth — no install needed, just open in the browser.

For advanced setups there is special firmware that makes the node accessible via WiFi or even VPN. This lets you configure and monitor your mountain repeater from home — or bridge entire mesh networks over the internet.

Bottom line: Whether smartphone app, browser or WiFi remote access — MeshCore offers the right access for every use case. As simple as WhatsApp, just without internet.

Anyone who hikes in Austria knows this: no signal at the summit, no reception in the valley, and certainly not in the hut. This is exactly where MeshCore shines — LoRa radio needs no cell network and still reaches over kilometers.

A small board on your backpack, and you can send messages to your group, share your GPS position or send an SOS call in an emergency. The range? In the Alps, over 45 km between two nodes has been documented — line of sight from peak to peak makes it possible.

For disaster preparedness, MeshCore is particularly interesting: When cell towers fail — due to storms, power outages or overload — the mesh network keeps working. Every node is independent, battery-powered, and the network repairs itself.

Bottom line: Whether mountain tour, festival, or blackout — MeshCore gives you communication when everything else fails. The Alps become the network.

What does a mobile contract cost you per year? 200 €? 300 €? MeshCore costs you exactly 0 € per month. No contract, no SIM card, no monthly fees. Ever.

MeshCore operates on the EU868 ISM band — a frequency that is license-free across all of Europe. You don't need a ham radio license, no permit, no registration. Just turn on and go.

The hardware is affordable: A Heltec V3 board costs around 20 €, a T-Beam with GPS about 35 €. Add a USB cable for flashing — done. The boards run for days on a small LiPo battery, a solar panel makes a repeater site completely self-sufficient.

Bottom line: Buy once, use forever. No hidden costs, no dependency on providers. That is true communication sovereignty.

MeshCore is not a product from a corporation that could be discontinued or hidden behind a paywall tomorrow. Everything is open source — the firmware, the companion apps, the flasher tools, even the hardware designs.

This means: Everyone can read, review and improve the code. No hidden backdoors, no telemetry phoning home, no vendor lock-in. If you're missing a feature, you can build it yourself — or ask the community.

Development happens transparently on GitHub. New firmware versions are tested by the community, bugs are discussed openly, improvement suggestions are welcome. The project lives from its users — from tinkerers in garages to engineers setting up repeater sites on mountain peaks.

Bottom line: Open source means trust. You don't have to take anyone's word that your communication is secure — you can verify it yourself. That is freedom.
