LoRa
LoRa, long-range modulation & packet mesh
Reticulum Network Stack: Cryptographic Addressing, Interfaces & Zero-Config
A deep dive into Reticulum Network Stack (RNS): self-sovereign cryptographic addressing, multi-interface transport, RNode LoRa links, LXMF, and Part 15 rules.
MeshCore Protocol: Structured Roles, Companion Topology & Repeaters
How MeshCore approaches sub-1GHz LoRa networking: distinct Companion, Repeater, and Room Server roles, deterministic routing paths, and AES-128 framing.
Meshtastic Off-Grid Messaging: Flood Routing, Airtime Budgets & FCC Limits
How Meshtastic builds peer-to-peer LoRa networks: managed flood routing, next-hop direct messaging, channel crypto, and why network hops are not FCC frequency hops.
LoRaWAN in the US: Architecture, US915 Channels, and Part 15 Reality
A builder's guide to LoRaWAN network architecture, US915 uplink/downlink channels, Class A/B/C receive windows, OTAA nonce traps, and FCC Part 15 limits.
What LoRa Actually Is: Physical Layer Mechanics, FCC Part 15, and the 1-Watt Trap
A builder's guide to Chirp Spread Spectrum physics, symbol time math, why 125 kHz LoRa cannot use the §15.247 1-Watt digital modulation shortcut, and how Part 15 differs from Part 97.
