Texas's massive geographic scale, diverse terrain, and large urban centers create distinct mesh networking environments across the state. The active tech and ham communities in major cities have driven early adoption. Dallas-Fort Worth Metroplex The DFW metro...

The Southeast US - from the Gulf Coast through the Appalachians - encompasses widely varied terrain and a large, dispersed population base. Mesh adoption varies significantly between urban and rural areas. Atlanta Metro Atlanta sits on a plateau of the Piedmo...

The Pacific Northwest's dramatic topography - Cascade volcanoes, the Olympic Peninsula, Puget Sound, and the Columbia River Basin - creates both exceptional repeater opportunities and challenging deployment conditions. Oregon Oregon's geography divides into d...

Alaska presents the most extreme deployment environment in North America - and arguably the most compelling use case for off-grid mesh networking. Communities separated by hundreds of miles with no roads, cellular coverage, or reliable communications infrastru...

Meshtastic's MQTT module extends a LoRa mesh network over the internet by bridging packets between the radio air interface and an MQTT message broker. A gateway node - a Meshtastic device with a working Wi-Fi or Ethernet connection - uplinks packets it hears o...

Any Meshtastic device with Wi-Fi capability (ESP32-based boards such as the LILYGO T-Beam, Heltec WiFi LoRa 32, RAK4631 with Ethernet module, etc.) can act as an MQTT gateway. This guide covers enabling MQTT through the official Meshtastic app and verifying th...

Eclipse Mosquitto is the de-facto standard open-source MQTT broker, widely used with Meshtastic for private mesh deployments. This guide installs Mosquitto on a Raspberry Pi or Ubuntu/Debian server, secures it with TLS, adds authentication, and optionally brid...

Node-RED is a browser-based visual programming tool built on Node.js, ideal for wiring together MQTT data streams from Meshtastic with downstream services such as dashboards, databases, and messaging platforms. This page covers installing Node-RED, subscribing...

If you have ever used Wi-Fi at home, you are already familiar with the most common type of wireless network: the star topology. Every device in your house - your phone, your laptop, your smart TV - talks to one central access point (your router), and the route...

LoRa stands for Long Range. It is a wireless radio modulation technique invented by a French startup called Cycleo and acquired by Semtech in 2012. LoRa chips appear in millions of devices worldwide today, from smart utility meters to wildlife trackers to comm...

One of the most common sources of confusion when starting out is the alphabet soup of acronyms: LoRa, LoRaWAN, Meshtastic, MeshCore. People use them interchangeably, but they are four very different things operating at four different layers. This page explains...

Every LoRa mesh device you buy for use in North America operates in the 915 MHz ISM band. Understanding what that means - and what the rules are - will help you choose the right hardware, set the right channels, and avoid interference with your neighbors. Wha...

This guide will take you from zero to sending a LoRa mesh message on Meshtastic, step by step. No prior RF or networking experience is required. If you get stuck, the What to Check sections at the end will help you diagnose the most common problems. Step 1: B...

MeshCore is a newer peer-to-peer LoRa mesh platform that differs from Meshtastic in some important ways. This guide walks you through buying hardware, flashing firmware, and sending your first message - including a plain-language explanation of what makes Mesh...

Having a single node transmitting into the void is technically functional, but the real magic of a mesh network only appears when you are connected to other people. This page explains how to find out whether there is already an active mesh in your area, what t...

How Antennas Work at 915 MHz An antenna is a transducer that converts electrical energy (RF current on a transmission line) into electromagnetic waves and vice versa. Understanding the physics of this conversion is essential for making informed antenna choices...

Antenna Types for LoRa Mesh Choosing the right antenna type for a LoRa mesh deployment is one of the highest-leverage decisions you can make. A 3 dB improvement in antenna gain doubles your effective communication range. This page describes the principal anten...

Antenna Gain and Coverage Tradeoffs Antenna gain is not free - it is always traded against something else. Understanding what gain costs you is essential before choosing an antenna for a mesh deployment. The fundamental law of antenna physics is conservation o...
