Community Mesh Networks:
"... what if your neighborhood could create its own independent, resilient communication grid? A simple, low-cost, and powerful network that you and your neighbors own and control, one that stays up even when everything else is down. This is the promise of a community mesh network."
"Building a mesh network sounds expensive and complicated, but new technology has made it incredibly accessible. We’re going to focus on a specific, beginner-friendly platform called Meshtastic. This open-source project is designed specifically for creating the kind of off-grid, long-range networks we need for emergency communications."
"To build your first node, you only need two things:
They aren’t really designed to extend an existing Wi-Fi network, but to replace it.
- A LoRa Device: These are small, all-in-one circuit boards that cost between $30-$50. They come with a LoRa chip, a small screen, an antenna, and often a GPS. Excellent, affordable options for beginners include the LILYGO T-Echo or the HELTEC LoRa 32 V3. You can find them on Amazon or from online electronics retailers.
- A Smartphone: The free Meshtastic app (available for Android and iOS) uses your phone’s Bluetooth to connect to your LoRa device. You use the app to type and read messages, just like any other texting app."

They comprise 2 or more Wi-Fi nodes that work together to offer a single Wi-Fi network (one SSID), and devices can hop seamlessly across the nodes as they move within the network."
