Concept relationships — summary objects¶
This page synthesizes how domain concepts relate: short summary objects (one-line roles + explicit relates_to edges) for agents and humans. Provenance remains on individual concept pages and source-notes; this is navigational structure only.
See also: Knowledge synthesis, LLM Wiki pattern.
Clusters (narrative)¶
LPWAN, Wi‑Fi, and mesh (field RF)¶
LoRa (radio) is the shared PHY for both LoRaWAN (star/gateway uplinks) and Meshtastic (mesh firmware). Wi-Fi HaLow is an alternative sub-GHz 802.11-family stack often compared to LoRa-class LPWAN for throughput/range tradeoffs—not the same PHY as LoRa.
Agriculture and edge compute¶
Precision agriculture is the management science framing; LoRaWAN and ESP32 appear as common telemetry / actuator layers in source material, not equivalents.
Time and infrastructure¶
Network Time Protocol (NTP) and Precision Time Protocol (PTP) are distribution/discipline protocols over IP/Ethernet; they pair with GNSS in sources but are not GNSS themselves.
Incentivized infrastructure¶
Decentralized physical infrastructure networks (DePIN) is an economic/architecture pattern sometimes listed beside LPWAN and 802.11ah in survey material—treat as orthogonal to PHY choice unless a source ties them for a specific deployment.
Meta (this vault)¶
LLM Wiki pattern describes raw vs wiki maintenance; it does not assert domain RF facts.

Limits¶
- Not a formal ontology — edges are pragmatic reading aids; refine when new sourced analyses appear.
- LLM Wiki pattern has empty
relates_toin YAML to keep domain RF concepts separate from meta.
