Q&A

Frequently Asked Questions#

Getting Started#

Should I install a relay? Yes! Even if you don’t think you can reach other nodes yet, you might be surprised. Every mesh starts with a single node; by setting one up, you create the foundation for the next neighbor to join.

What hardware should I buy? It depends on your goals, but for beginners, the HELTEC v4 is a great, low-cost way to start experimenting. If you plan to mount a node outdoors, consider a self-contained solar node to avoid the hassle of running power cables to your roof. Check our Hardware Guide for vetted recommendations.

Do I need to put an antenna on my roof? No. Many users run successful relays from living rooms, attics, or even backpacks. However, height is king in radio; placing a node on a roof, tree, or mast will significantly increase your range.

Range & Connectivity#

How far can I communicate? "As far as the eye can see." While the world record is over 300km, practical everyday range is typically a few kilometers from inside a house. A rooftop node can easily reach 12km or more, depending on the terrain and line-of-sight.

Why can't I see anyone on my radio? You may be blocked by a physical obstacle (like a hill or building) or simply too far from the nearest relay.

  • Wait: Relays announce themselves periodically; stay tuned for a few minutes.
  • Check Maps: Consult the Live Maps to see if there is active infrastructure nearby.
  • Reach Out: Send a !ping or a "Hello" on the LongFast channel. Sometimes people are listening but not talking.

How many nodes are currently in the network? It varies daily. Maps typically show 20 to 40 active nodes across the region. On a typical day, a well-placed home station can expect to see 10–20 relays and maintain about half a dozen direct contacts.

Legality & Security#

Is this legal to use in Canada? Yes. Meshtastic and MeshCore operate on the 915MHz ISM band, which is license-exempt for end-users. While the LoRa protocol itself is patented by Semtech, using these devices is perfectly legal.

Are my messages private? It depends on the channel:

  • LongFast: This is the "public square." While technically encrypted, it uses a universal public key. Treat it like a public billboard.
  • Private Channels: These offer more secrecy, but Meshtastic lacks "perfect forward secrecy." A sophisticated attacker could potentially replay messages or see which nodes are communicating. For mission-critical security, projects like Reticulum are being explored.

Protocols & Standards#

Why use Meshtastic instead of Reticulum or MeshCore?

  • Reticulum has superior cryptography but is currently less "plug-and-play" than Meshtastic.
  • MeshCore offers better scalability for cities but has had some historical concerns regarding app licensing and encryption standards (like the "ECB Penguin" problem). Currently, we use Meshtastic because it has the "critical mass" of users and hardware that just works out of the box.

Why are we using the "LongFast" setting? We stick to the LongFast default (with a 3-hop limit) to ensure maximum compatibility with the most users. While some high-density areas in the US have moved to custom settings to avoid congestion, the Canadian mesh is not yet saturated. We will adapt our standards as the network grows.
