Recently, we have noticed that many places have experienced network outages, so we have focused on off-grid technology.
What is off-grid technology?
Off-grid technology refers to systems and devices that operate independently of traditional centralized infrastructure, such as power grids, internet providers, or cellular networks. These technologies enable self-sufficiency and resilience, making them useful for remote locations, emergencies, and decentralized applications.
Off-grid Communication Plans
Meshtastic LoRa Mesh Network
-
Uses low-power, long-range radios to form a self-sustaining communication network.
-
Ideal for outdoor adventures, emergency preparedness, and decentralized messaging.
-
Supports encrypted communication and GPS tracking for enhanced functionality.
LoRaWAN Community Networks
-
Some cities and rural areas have community-driven LoRaWAN networks that allow decentralized communication.
-
Example: The Things Network, which enables users to set up their own LoRaWAN gateways for IoT and messaging.
HAM Radio Mesh Networks
-
Amateur radio operators use digital mesh networks like AREDN (Amateur Radio Emergency Data Network) for off-grid communication.
-
These networks provide high-bandwidth data transfer over long distances without relying on the internet.
goTenna Mesh
-
A commercial alternative to Meshtastic, goTenna Mesh uses Bluetooth and long-range radio to create peer-to-peer messaging networks.
-
It’s often used for emergency response and outdoor adventures.
Serval Mesh
-
An open-source project that enables off-grid mobile communication using Wi-Fi and Bluetooth.
-
Unlike Meshtastic, Serval Mesh focuses on smartphone-based mesh networking.
DIY Off-Grid Networks
-
Some enthusiasts build custom LoRa-based networks using ESP32 and Raspberry Pi devices.
-
These setups can integrate GPS tracking, encrypted messaging, and sensor data transmission.
Which off-grid technology do we choose?
Meshtastic, of course
Why We Choose Meshtastic
Because Meshtastic offers a decentralized, long-range, and low-power communication solution without relying on cellular networks or the internet. Here are the key reasons why it stands out:

Meshtastic operates on LoRa (Long Range) radio technology, allowing it to cover several kilometers with minimal power consumption.
-
Ideal for outdoor adventures, emergency response, and off-grid living.
Open-Source and Customizable
-
The platform is open-source, meaning users can modify and improve the software to fit their needs.
-
Developers and hobbyists appreciate the flexibility to create custom applications.
Privacy and Offline Communication
-
Since Meshtastic doesn’t rely on centralized infrastructure, it enables private, encrypted communication.
-
Perfect for protests, disaster scenarios, and wilderness expeditions.
User-Friendly Interface
-
Despite its advanced capabilities, Meshtastic is designed to be easy to set up and use.
-
The mobile app simplifies configuration, messaging, and GPS tracking.
Affordable and Accessible
-
Meshtastic runs on low-cost, off-the-shelf hardware, making it an affordable alternative to satellite phones or commercial mesh networks.
-
Devices like LILYGO T-Beam and Heltec LoRa 32 are popular choices.
