Reticulum is not a messenger, not a VPN and not a "network for shady business". It is a complete network stack in which the address is a key fingerprint, encryption has no off switch, and the carrier can be a LoRa radio, a piece of wire or ordinary TCP. This note takes it apart layer by layer: from the bits in the packet header to the board on the desk. The radio physics underneath is in the LoRa deep dive.

Meshtastic is not a stack or a platform but a finished product: a cheap board with a LoRa radio, a phone over Bluetooth — and a chat that works where there is neither mobile coverage nor internet. This note is about how exactly a message hops through other people's nodes, how much airtime that costs and why a mesh chokes when there are too many nodes. The radio physics underneath is in the LoRa deep dive.

Meshtastic and Reticulum sit on the same physics: a modulation that reads a signal weaker than the noise floor and pays for it in time. This note is about that physics: how a chirp works, where the range comes from, what every knob in the settings does, what the hardware is made of and what gets built on top — from LoRaWAN to drones and satellites.
