This may be obvious, but you also need to have a network set up before disaster hits, Meadows says. So, set up anyone who you might need to communicate with during a cell and internet blackout before it actually happens. And, due to relatively frequent firmware updates, you can’t just toss your device in a bug-out bag and forget about it. But “if it’s something that you actually use, like if you pull it out and use it once a month, you’ll be good to go,” Bennett says.
Then there’s the issue of raw bandwidth. This limitation can cause issues when a lot of people are trying to use the network at the same time. At a ham radio convention in Dayton, Ohio, last year (yes, it’s called Hamvention), the Meshtastic network crashed after someone ran a program that flooded the network with additional traffic, pushing the Meshtastic network to its limits.
“Because literally one person turned on this MQTT bridge, which then joined the rest of us into this mesh in a metal building in Dayton, it crashed the whole mesh immediately,” Vander Houwen says.
After this incident, Vander Houwen, Bennett, and Meadows went to work to prepare for the upcoming Defcon hacker convention in Las Vegas, ultimately releasing a special firmware for the much larger event that Vander Houwen estimates allows “somewhere between 2,000 and 2,500 nodes” to operate on the network simultaneously. A similar firmware released ahead of the 2025 Hamvention in May drew praise from the community.
Despite Meshtastic’s limitations, its promise as a backup communication system—and the sheer fun you can have with it—continues to pull in new enthusiasts. The Android app alone has drawn thousands of reviews, and the Meshtastic subreddit has grown to nearly 50,000 members. Some municipalities are even hoping to launch Meshtastic networks to help protect their communities in the event of natural disasters.
For Bennett, Meadows, and Vander Houwen, they’re excited to not just see the number of Meshtastic nodes increase, but to see the technology develop into something anyone can use without having to become an enthusiast or “analog astronaut” at all.
“I think the biggest thing for me too is that it’s not just accessible from the aspect of the hardware being available to more people. I want to make the software more accessible,” Meadows says. “I want to make the experience such that I can hand this device to anybody and have them download the app and start messaging. We’ve come a long way. I think there’s still some room to grow there.”
