Why MeshCore Netherlands?
A growing LoRa mesh network for emergency communication in the Netherlands
What is MeshCore Netherlands?
MeshCore Netherlands is a LoRa mesh network technology focused on reliability, privacy, and ease of use. The network is rapidly growing in the Netherlands and is actively used here for emergency communication. The community is also growing internationally, with websites like MeshFan sharing information worldwide.
For LocalMesh, MeshCore is interesting because it can also be a practical option for emergency communication in busy and built-up areas.
Note: LocalMesh has no commercial ties with MeshCore. We are an independent Dutch citizen initiative that uses this technology because we believe it's the best solution for emergency communication in the Netherlands.
What Makes MeshCore Special?
Encrypted Communication
Supports end-to-end encryption for private conversations.
Energy Efficient
Batteries last days to weeks, ideal for emergency situations.
Greater Reach via Repeaters
With repeaters, messages can hop further than a direct connection, depending on coverage and the available nodes around you.
Self-Healing
The network automatically finds new routes when devices fail.
Easy to Use
Connect via Bluetooth to your phone and send messages through the app.

MeshCore Firmware Types
MeshCore offers four different firmware types, each with a specific function. Which firmware you need depends on how you want to use the device:
BLE Companion
Connects via Bluetooth to your Android or iOS smartphone. This is the standard choice for daily use – open the MeshCore app and you can send messages.
USB Serial Companion
Connects via USB cable to your computer or the web client. Useful for configuration or if you prefer not to use a smartphone.
Repeater
Extends the range of the network by forwarding messages. Repeaters work completely autonomously and can be managed remotely.
Room Server
A bulletin board where users can post and read messages. The server stores message history and pushes updates to connected users.
💡 Tip
Start with BLE Companion firmware on your first device. This way you can get started right away with your phone. Got a second device later? Turn it into a repeater to extend your range.
How Does MeshCore Work?
MeshCore uses LoRa (Long Range) radio technology to send messages. Here's how it works in simple terms:
You Send a Message
Via your phone, you type a message. This is sent via Bluetooth to your LoRa radio device.
The Device Transmits the Message
Your device sends the message via LoRa. Range depends on height and antenna – from a few hundred meters at ground level to 30-40 km from a high point.
Repeaters Forward It
If the recipient is too far away, repeaters (relay stations) automatically forward the message. This can gradually extend range, depending on the network around you.
The Recipient Receives the Message
The message arrives at the recipient, who sees it appear on their phone.
🧠 The Smart Part: Path Discovery
MeshCore uses a system called "path discovery". This means the network intelligently searches for the best route for your message. No flooding (unnecessarily sending many messages), but efficient routing. This saves energy and makes the network faster.
Why MeshCore and Not Meshtastic?
You may have heard of Meshtastic, a popular international mesh protocol. LocalMesh deliberately chose MeshCore for the Netherlands because, in our view, it fits our emergency communication goals better:
| Property | MeshCore | Meshtastic |
|---|---|---|
| Routing | ✓ Path discovery (smart) | Flooding (wasteful) |
| Energy Consumption | ✓ Very Low | Low to Medium |
| Privacy | ✓ E2E for private chats | E2E optional |
| Network Load | ✓ Low (efficient) | High (many redundant messages) |
| Reliability | ✓ High (targeted routes) | Medium |
| Performance Busy Areas | ✓ Excellent | Moderate (network fills up quickly) |
In short: For LocalMesh, MeshCore is currently the most logical choice, mainly because of its smart routing, low energy use, and focus on more efficient network load.
Technical Specifications
For the tech-savvy among us, here are the technical details:
- → Frequency: 868 MHz (European ISM band, no license needed)
- → Modulation: LoRa (Long Range)
- → Range: Depends on height and antenna. With repeaters, range can increase significantly, depending on coverage and how the network is built.
- → Encryption: AES-256 for private messages
- → Data rate: 0.3 - 50 kbps (depending on spreading factor)
- → Power: Max 25 mW (within legal limits)
- → Topology: Mesh network with path discovery routing
- → Protocol: Custom protocol on top of LoRa PHY layer
Is MeshCore Legal in the Netherlands?
Yes, absolutely. MeshCore uses the 868 MHz frequency band, which is freely available in Europe (ISM band) without a license. As long as you stay within legal power limits (25 mW), you may use this technology.
✓ No License Needed
✓ Fully Legal in the Netherlands and EU
✓ Falls Under ISM Band (Industrial, Scientific and Medical)
