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 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 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.

Rain, wet foliage, temperature inversions, and ice all affect Meshtastic range in different ways. Some are obvious. One is genuinely counterintuitive.

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 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.

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.

LoRaWAN is the open network protocol that turns LoRa radio into a managed IoT system, connecting battery-powered sensors to the cloud over kilometres. Here is how it actually works, from gateways to network servers, and how to start using it.

LoRa modulation is controlled by three parameters: spreading factor, bandwidth, and coding rate. Here is what each one does and how to think about the trade-offs between range, speed, and airtime.

LoRa is the radio technology. LoRaWAN is the network protocol built on top of it. Here is what that actually means in practice, and when you would use each one.

LoRa is the radio technology behind Meshtastic, LoRaWAN, and thousands of IoT projects. Here is what it actually is, how chirp spread spectrum works, and why it reaches so far on so little power.

Meshtastic can work indoors, but LoRa radio signals and thick walls are not a happy combination. Here is what you can realistically expect.
By BFGNeil on 5/3/2026
LoRa is the radio technology. Meshtastic is software that runs on top of it. They are not competing options, they are layers of the same stack, and knowing how they relate helps you understand what Meshtastic actually is.

Getting more range from your Meshtastic node comes down to three things: a better antenna, more height, and understanding what the radio signal actually has to deal with.

Meshtastic works without the internet, without a mobile network, and without any central infrastructure at all. Here is how that is possible and what it means for how you use it.
By BFGNeil on 5/2/2026
Meshtastic itself is free, open-source software. But you do need hardware to run it, and that costs money. Here is exactly what you need to get started and what it will set you back.
By BFGNeil on 5/2/2026
This is the first question everyone asks when talking about meshtastic.Not "what hardware do I need" or "how do I set it up." Just — how far does this thing actually go?
By BFGNeil on 5/2/2026
Meshtastic lets you send messages without a phone signal, Wi-Fi, or any central infrastructure. Here is how off-grid messaging actually works, from the hardware in your hand to the network it creates.
By BFGNeil on 5/2/2026
Meshtastic messages do not just travel in a straight line from one device to another. They hop through a network of nodes, and understanding how that works explains both what Meshtastic can do and where its limits are.
By BFGNeil on 5/2/2026
Poor Meshtastic range is one of the most common complaints from new users, and it is almost always fixable. Here are the real reasons your signal is falling short and what to do about them.
