Low-earth-orbit satellite internet (e.g. Starlink-type terminal), roughly 99.1% measured uptime (about 13-34 minutes of daily downtime from handoffs/weather), independent of local fixed-line or cellular tower infrastructure, making it a genuinely different failure domain from either. Not bulletproof on its own, weather-sensitive, congestion at peak hours, weaker uploads, which is why it's best paired with, not substituted for, fixed broadband and cellular rather than relied on alone. Needs continuous power for the terminal itself, a clear sky view, and is fully proprietary hardware/subscription.
Note: Cost, carbon and footprint are rated against the other options for this same need, not in absolute terms.
Clear sky view (no dense tree canopy or structure overhead)
No sizing or quantities: how much a technique yields, and how much a household needs, both depend on the build and the people, so the catalogue compares options rather than dimensioning them. It carries no bill of materials and no build sequence, and it is written for an oceanic, clay-soil climate (Normandy, France). Regulatory notes are indicative and need confirming locally.
