Meshtastic: Open source project to send/receive text messages without smartphone using LoRa (Long Range Radio). Connects even deep in mountains or during disasters.
3
Mesh Network: Terminals relay radio waves like a bucket brigade. 'Decentralized Infrastructure' where coverage expands as users increase.
4
Hardware (LILYGO T-Deck): Terminal with keyboard like BlackBerry. Complete with just this device. Saves smartphone battery.
5
Encryption: Communication is encrypted with AES-256. No logs left on carrier. Complete privacy.

Introduction: Doubt the Infrastructure

“It’s natural for smartphones to connect.” When that premise collapses (disaster, communication failure, censorship), how do you contact your family?

Amateur radio license is not required. In 2026, using LoRa (Long Range) technology, anyone can chat with someone kilometers away. This is not “Play” but “Survival Skill”.

1. What is Meshtastic?

Meshtastic is an open source mesh network developed for mountaineers and glider pilots. There is no central server. No base station. The device you hold becomes the base station.

Mesh Technology

Mr. A and Mr. C are too far apart to communicate. However, if Mr. B is in the middle, radio waves are relayed (Hop) as A -> B -> C. If nodes (terminals) increase in the city, theoretically the entire city can be covered.

2. The Device: LILYGO T-Deck

There are types that connect to smartphones via Bluetooth, but the one with romance is the “Standalone Machine”.

Modern pager equipped with trackball and QWERTY keyboard. ESP32-S3 and LoRa module built-in. Experience of taking it out of pocket and typing message with physical keys is Cyberpunk itself.

3. Use Cases: When to use?

Disaster

Even if mobile base stations black out, LoRa works. Runs for days with one mobile battery. If every family member has one, survival reports like “I’m at the shelter” will definitely arrive.

Privacy

Does not go through carriers (AT&T/Verizon/T-Mobile). All messages are end-to-end encrypted. Even metadata like “Who communicated with whom and when” is unknown to third parties.
