Field node classes (G/R/S/H/W) — off-grid farm roles¶

Purpose¶

Durable architecture labels for field nodes: G (gateway/spine), R (mesh repeater), S (sensor leaf), H (sub-GHz IP bridge, e.g. HaLow segment), W (WAN edge). These are roles, not product SKUs—analyses cite them to avoid re-typing the table.

Scope¶

• In scope: Power posture expectations, local-first vs WAN-dependent behavior, pilot discipline (one spine family until evidence gates pass—see linked analyses).
• Out of scope: Vendor/model picks, per-site mount heights, or firmware versions (deployment evidence).

Knowns¶

• The vault’s canonical elaboration with a full table and diagram is the Demory SITE_FARM doctrine (below).
• W is egress-oriented and is typically not in the Pcrit default for local delivery paths.

Assumptions¶

• The same letter taxonomy may apply to other farms only after local validation (power, RF noise, coverage).

Related analyses¶

• Field-node classes and communication roles — Demory farm site
• Mesh and field networking strategy — off-grid Demory
• Off-grid infrastructure stop rules — Demory (DR-* gates)
• Field telemetry network — two-site

Related source notes¶

• Off-grid power, field RF, and optional WAN — source index (Demory planning)

Outstanding unknowns¶

• Which concrete hardware instances will implement G vs R at each site after pilot recon.
• Whether a second WAN path is justified (economic and DR-2 evidence).
