Node ↔ Node over LoRa
Two Meshium Nodes talk directly to each other over LoRa — without internet, Wi-Fi, SIM or cloud.
Off-grid communication network
The secure off-grid network for people, devices and industry.
A self-expanding communication layer that works without mobile networks, internet or cloud dependency — built with Post-Quantum Security from day one.

Why Meshium
A second, independent communication layer.
Today everything runs through mobile networks, internet, cloud or satellite services. They are powerful — until they fail, get congested, or are simply not available. Meshium does not replace them. Meshium adds a local, decentralised layer that keeps people, devices and industry connected when central infrastructure cannot.
Why not just a phone?
Phones depend on mobile coverage and an active SIM. The moment a tower drops or a network gets congested, the conversation stops. Meshium works locally even when no mobile network is in reach.
Why not just satellite?
Satellite phones are expensive, slow for everyday traffic, and rely on subscriptions and clear-sky conditions. Meshium is a low-cost local layer that complements satellite, not competes with it.
Why not just standard mesh gadgets?
Off-the-shelf mesh radios are hobby-grade and not designed for everyday users, families or industrial use. Meshium is being built as its own ecosystem — app, firmware, hardware, protocol — for serious daily use.
And no — Meshium is not Meshtastic.
Meshium is an independent project with its own app, its own firmware, its own hardware and its own protocol. It is not a fork, clone or extension of Meshtastic.
Meshium is the additional layer that stays online when other networks go offline — for private messages, important alerts, sensor data and machine status.
The problem
Connected everywhere — until the network fails.
Modern communication depends on cell towers, internet, cloud platforms and centralised services. The moment any of them fails, conversations and critical data flow stop — for people and for machines.
Coverage gaps
Remote trails, valleys, basements, mountains, large industrial sites — coverage drops exactly where it matters.
Congested networks
Crowded events, public holidays and disasters overload mobile networks; messages get delayed or fail entirely.
Power and cloud outages
When power, internet or cloud platforms go down, messengers and platforms go down with them.
Crisis situations
Storms, floods and outages are exactly when communication must keep working — and is most likely to break.
Expensive specialist solutions
Satellite phones and industrial radios are powerful but costly, complex and not built for daily life.
Sensors in remote locations
Tank levels, weather stations, gates and pumps often sit in places without stable connectivity — yet must report.
The solution
Meshium creates a second communication layer.
Meshium does not replace the internet — it adds a local, secure layer next to it. A self-expanding network of small Meshium devices that carry private messages and small but important data when central infrastructure is unavailable, congested or simply too far away.
Meshium devices forward messages and data for each other without being able to read private content, so the network can grow organically while private conversations stay private.
Works without mobile networks
Communicate where there is no cellular signal at all.
Works without internet
No WiFi, no data plan, no central server required for local communication.
No SIM, no cloud dependency
Your Meshium device is the network — nothing to register, nothing to top up, no cloud lock-in.
For people and devices
Private messages, alerts, sensor data and machine status all travel over the same layer.
Devices relay automatically
Every Meshium Node, Mini and Gateway can forward traffic for the others, extending reach without effort.
One ecosystem
Node, Mini, Gateway and the Meshium app share one protocol, one security architecture and one app.
How it works
From your phone to theirs — without the internet.
Meshium is designed to feel as simple as a normal messenger, while running on a completely independent communication layer.
- 01
Open the app
The Meshium app starts up — no SIM, no setup wizards, no accounts to register.
- 02
Auto-detect via BLE
The app discovers your Meshium Node, Mini or Gateway over Bluetooth and pairs automatically.
- 03
Secure session
A secure session is established between the app and the Meshium device.
- 04
Send a message or data packet
Private messages, alerts or small data packets from sensors and machines are encrypted on the device.
- 05
Relayed across the mesh
Nearby Meshium nodes automatically forward the encrypted packet across the network — without being able to read it.
- 06
Delivered privately
The recipient receives the message or data through their own Meshium device, where it is decrypted and shown in the app.
Self-expanding network
Every device makes the network stronger.
Meshium is not just a device — it is a network that grows with its community. Every Meshium Node, Mini and Gateway can act as a relay. The more Meshium devices exist in an area, the wider the reach, the more redundancy, and the more reliable the connection becomes — for people, sensors and machines alike.
- Meshium Node, Mini and Gateway are fully compatible — each can relay for the others.
- Designed to grow organically — no central operator, no per-user licensing.
- Add a node at home, on a campsite, in a workshop or on an industrial site to extend the mesh.
- Coverage scales with adoption, not with infrastructure spending.
Local-first · Gateway-optional
Three ways Meshium connects.
Meshium runs locally without internet. When internet is available, it can be used optionally to bridge separated local Meshium networks — never as a hard dependency.
Mode 02 · Mesh extended
Node ↔ Mini ↔ Node
Meshium Mini nodes extend the network and forward sensor events, so messages can hop further across a local area.
Mode 03 · Gateway-optional
Network A ↔ Gateway ↔ Internet ↔ Gateway ↔ Network B
When internet is available, a Meshium Gateway can optionally bridge separated local Meshium islands. Optional, not required for local use.
Local when you need independence. Connected when you choose it.
Current prototype
This is not just a concept — it already runs.
Meshium is already moving small data through a working hardware prototype. App messaging over BLE and LoRa, the Meshium Mini as a small node, and a real sensor-to-LoRa alert chain — all live today, without Wi-Fi, mobile networks or cloud services.
Demo 01 · App + LoRa
Send a message from app to receiver
The Meshium app pairs with the Meshium Node (sender) over BLE, sends a message, and a second Meshium Node (receiver) picks it up over LoRa.
- 1App connects to Meshium Node (sender) via BLE
- 2User sends a message in the app
- 3Meshium Node (sender) transmits the message over LoRa
- 4Meshium Node (receiver) receives the packet
- 5Receiver dashboard shows RX message, RSSI and SNR
Demo 02 · Mini node
Meshium Mini as a small network node
The Meshium Mini (Seeed XIAO nRF52840 + Wio-SX1262) periodically announces itself on the network and is picked up by the Meshium Node (receiver).
- 1Meshium Mini boots and initialises LoRa
- 2Mini broadcasts a HELLO packet every 10 s
- 3Meshium Node (receiver) picks up the HELLO over LoRa
- 4Receiver dashboard shows Mini as part of the mesh
Demo 03 · Sensor → LoRa alert
A PIR motion sensor sends a LoRa alert
An AM312 PIR sensor on an ESP32-C3 advertises a BLE motion event. The Meshium Mini picks it up and forwards it as a LoRa alert to the Meshium Node (receiver) — no Wi-Fi, no cellular, no cloud in between.
- 1AM312 PIR sensor detects motion
- 2ESP32-C3 sends a BLE event (MESH-PIR-001)
- 3Meshium Mini receives the BLE event
- 4Mini transmits a LoRa ALERT (motion_detected)
- 5Meshium Node (receiver) shows motion_detected on the dashboard
Live status in the current prototype
LoRa·liveBLE·liveGPS·liveBattery·liveSecurity·demoPQC·ready
The security and PQC layer is wired into the protocol and visibly prepared in the demo. The full cryptographic implementation is still being built out — see the Security and Roadmap sections.
“Meshium started as off-grid communication for people. The bigger idea is a local communication layer for people, devices and sensors.”
Security architecture
Built for the post-quantum era.
Meshium’s security architecture is built into the foundation of the system — app, firmware, hardware and protocol — instead of being added on top. The goal is a future-ready design that can evolve as cryptography itself evolves, providing long-term trust for people, devices and industry.
Post-quantum-ready security layer
Post-Quantum Security from day one
Meshium is being designed for the post-quantum era — modern cryptography is part of the foundation, not a later upgrade.
Relay without reading
Meshium devices forward encrypted packets through the mesh. Relays move messages, not their content.
Private messages stay encrypted
Private conversations remain encrypted as they travel — also when other people’s devices help carry them.
Device identity
Each Meshium device is built to identify itself cryptographically inside the network, so peers can recognise who they are talking to.
Signed firmware updates (planned)
Firmware updates are planned to be cryptographically signed, so devices can verify the authenticity of every update.
Independent audits planned
Independent security audits are planned before final release. Security is treated as a core design goal, not a marketing claim.
Note: Meshium does not make absolute security claims. No system can be guaranteed to be unbreakable. Meshium’s goal is a security-first architecture that is openly described, continuously improved, and verified through independent audits before final release.

How Meshium compares
A different category of communication.
Meshium is not a replacement for everything else — it is an additional, decentralised layer for important messages and small data. The table below sketches the design intent of Meshium against five common reference points. Meshium is not Meshtastic; it is its own ecosystem.
| Capability | Mobile networks | Internet / cloud | Satellite phones | Walkie-talkies | Standard mesh gadgets | Meshium |
|---|---|---|---|---|---|---|
| Works without mobile networks | ||||||
| Works without internet / cloud | Varies | |||||
| No SIM card required | ||||||
| App-based interface | Varies | Varies | ||||
| Dedicated hardware ecosystem | Varies | Varies | ||||
| Automatic device-to-device relays | Varies | |||||
| Carries data from sensors and machines | Varies | Varies | Varies | |||
| Post-quantum-ready security design | ||||||
| Designed for everyday use, not hobby | Varies | Varies |
This comparison is illustrative and reflects design intent. Capabilities of other systems vary across vendors and versions; “standard mesh gadgets” refers to general categories rather than any specific product. Meshium is not Meshtastic.
For developers & makers
A platform for builders.
Meshium is being designed as a long-term platform — not just an end-user product. Developers and makers should be able to build on top of it, integrate sensors and create their own applications on the Meshium layer.
Developer access, SDK details and APIs will be announced as the platform matures. Support for makers and developers is part of the long-term roadmap.
01
Own protocol
Meshium ships with its own protocol, designed for small, important data packets across a self-expanding mesh.
02
SDK & API (planned)
A Meshium SDK and API are planned, so developers can build apps and services on top of the network.
03
Sensor integration
Devices and sensors will be able to plug into Meshium and send small status and event data.
04
Custom applications
Build your own apps — for monitoring, alerting, communities, industrial dashboards and more.

For investors & partners
Why Meshium, and why now.
Meshium is being built as a long-term platform for private off-grid communication for people, devices and industry. The thesis is simple: as the world becomes more connected, the value of independent, community-owned communication grows with it.
A growing need for resilient communication
Reliance on centralised infrastructure keeps growing — and so does the demand for communication that does not depend on it.
An ecosystem, not a single device
Meshium combines hardware, firmware, app, security layer and a community-driven mesh into one integrated platform.
Scalable product family
Meshium Node for personal use, Mini for sensors and relays, Gateway as the optional internet bridge — with sensor, industrial and SDK products planned next.
Built for the post-quantum era
Post-Quantum-ready security as a foundational design choice — positioning Meshium for long-term trust.
Possible future revenue streams
Long-term, Meshium can support a layered business model around the core hardware:
- Accessories
- Pro-tier devices
- Community nodes
- Business / industrial bundles
- App premium features
- Service & support packages for companies and events
These are directional possibilities, not commitments. The current focus is delivering a high-quality first product line and growing the network.
