Frequently Asked Questions #
Do I need a ham radio license? #
No. Meshtastic operates on the 915 MHz ISM band in the US, which does not require a license. Anyone can use it up to 1 watt of transmit power, which all commercially available radios operate under.
How far can Meshtastic communicate? #
Range depends heavily on terrain and line of sight. On ground level, you can expect a couple of miles between two handheld nodes. With properly placed nodes on hill tops or rooftops though, your node can connect to a wide network of other devices that will retransmit your messages as far as they can, each jump potentially expanding 20 miles each hop.
Is it private? #
Meshtastic supports encrypted direct messages between devices. The default channel is unencrypted and visible to all nodes — think of it like a public bulletin board. Private channels with encryption keys can be configured for group or one-to-one communication, as well as end to end encryption in direct messages
What does it cost? #
A basic Meshtastic node costs $30–$60. There are no recurring fees — no subscriptions, no service plans. The network runs on volunteer-operated infrastructure with no central authority.
Can I use it without a phone? #
Yes. Many devices have a built-in screen for sending and receiving messages. However, the phone app provides a much better user experience and is recommended for most users. If you would like to use a standalone device, we recommend the LilyGo T-Deck, ensure you get the 915mhz option.
How can I help expand the network? #
The most impactful thing you can do is set up a fixed node at elevation — on a rooftop, in an attic window, or on a mast. Solar-powered nodes in remote high-terrain locations are especially valuable. See the Get Started guide for hardware recommendations. Also - ensure you do not set your node to router unless you are sure it is the right choice. Clients will rebroadcast packets and are normally the right choice even for well placed nodes.
What about bad weather and power outages? #
LoRa radios use very little power. A node with a small solar panel and battery can run indefinitely. The mesh is decentralized — if individual nodes go offline, messages route around them. This makes the network inherently resilient during storms and power outages.
