LoRa Link Budget Explained: How to Calculate Whether Your Signal Will Reach
A link budget tells you whether a LoRa signal will reach its destination and by how much. Here's how to calculate one and what the numbers actually mean.
How to Configure Meshtastic Channels for Private Messaging
Meshtastic's default channel is open to anyone nearby. Here's how to set up a private channel with a custom encryption key so only your group can read your messages.
Meshtastic MQTT: Connecting Your Mesh to the Internet
Your Meshtastic mesh can bridge messages to the internet via MQTT, connecting with nodes in other cities and feeding data into tools like Home Assistant. Here is how the setup works and what to watch out for.
How Meshtastic connects to your phone: BLE, WiFi, and USB compared
Meshtastic nodes can connect to your phone or computer three ways: Bluetooth, WiFi, and USB. Here is when each one makes sense and which to reach for first.
Meshtastic Encryption: How Secure Is It Really?
Meshtastic uses AES-256 encryption on every channel. Here is how it actually works, what the default channel does and does not protect, and where the real risks are.
Meshtastic Node Roles Explained: Client, Router, Repeater, and When to Use Each
Meshtastic gives every node a role that controls how it behaves in the mesh. Here is what each role actually does and when to use it.
How Weather Affects Meshtastic Range (Yes, It Does)
Rain, wet foliage, temperature inversions, and ice all affect Meshtastic range in different ways. Some are obvious. One is genuinely counterintuitive.
What Is a Meshtastic Repeater Node and When Do You Need One?
A Meshtastic repeater node bridges gaps that direct links cannot cross. Here is what one does, when you actually need one, and how to set it up properly.
RSSI and SNR explained: how to read your LoRa signal quality numbers
RSSI and SNR are the two signal quality numbers you will see most in Meshtastic and LoRa. Here is what they actually mean and how to use them to understand a link.
How Many Meshtastic Nodes Do You Need for Good Coverage?
Planning a Meshtastic network? The answer to how many nodes you need isn't just about quantity. Placement and elevation matter far more than most people expect.
Meshtastic Line of Sight Explained (and Why It Matters More Than Power)
Line of sight explains more about Meshtastic range than transmit power, antenna upgrades, or spreading factor combined. Here is what it actually means in radio terms, why height clears the Fresnel zone, and how to use this to get real coverage improvements.
