General Questions

What is LoRa mesh networking?

LoRa mesh networking is a way for people to communicate using small radio devices, without any internet connection, cell towers, or central infrastructure. Each device can receive messages and forward them to others, forming a self-organizing network.

How does mesh networking work?

Each device in the network can receive and forward messages. When you send a message, it travels through multiple devices (hops) until it reaches its destination. The network routes around failures automatically — there is no single point of failure.

What is the range?

Direct line-of-sight range between two devices can reach 10+ kilometers under ideal conditions. Ground-level urban range may be just a few hundred meters. The real power of mesh networking is that messages hop through repeaters and other nodes, potentially covering hundreds of miles across the network.

Do I need a license to operate?

No. Both MeshCore and Meshtastic operate on the 915 MHz ISM band in the US, which is license-free under FCC Part 15 rules. No amateur radio license is required.

Is my communication private?

It depends on the platform and channel:

• MeshCore — private messages are end-to-end encrypted by default. Public channel messages are visible to all nodes in range.
• Meshtastic — the default public channel uses a well-known shared key, making messages readable by anyone running Meshtastic. Private channels with custom keys provide better privacy.

Can MeshCore and Meshtastic devices communicate with each other?

No. MeshCore and Meshtastic use different protocols and cannot communicate with each other. If you want to communicate with people in your area, find out which platform they use first.

Is this active in my area?

Coverage depends entirely on community participation. In areas with active members and deployed repeaters, the network can extend for hundreds of miles. In areas without existing nodes, you may need to start building local coverage yourself. Check the network map for your platform to see current nodes near you.
