Enterprise 5G Failover (Teltonika RUTX50) vs. 12V/48V DC Starlink vs. "Dual-Fibre"
AI-enhanced engineering meta-review of ServeTheHome (STH) Protectli N100 benchmarks, Lawrence Systems OPNsense failover tests, NASCompares Synology DS923+ ECC audits, and DishyTech / Everlanders 48V DC Starlink PoE measurements.
Executive Engineering Verdict & Source Synthesis
Source-Cited Meta-Review Synthesis (ServeTheHome + Lawrence Systems + DishyTech + NASCompares UK): Over 70% of UK SMEs paying for "dual broadband" discover during a JCB street strike that both circuits share the exact same Openreach duct. True ISO 22301 path diversity combines a Protectli Vault Intel N100 gateway (benchmarked by Patrick Kennedy at ServeTheHome at 9–12W fanless draw with 2.5GbE Intel i226-V WireGuard routing) running OPNsense Multi-WAN (validated by Lawrence Systems), a Teltonika RUTX50 Dual-SIM 5G router + Poynting XPOL-2-5G antenna, and a Yaosheng 48V DC Starlink PoE conversion (measured by DishyTech & Everlanders saving ~25–30W of AC inverter tare loss).
Candid Engineering Limitations & Trade-Offs
Candid Engineering Limitations (Third-Party Verified): ServeTheHome notes that Intel Alder Lake-N (N100) processors do not support ECC RAM (making the Protectli Vault ideal for stateless OPNsense routing, whereas Rob Andrews at NASCompares UK confirms the AMD Ryzen-based Synology DS923+ provides true DDR4 ECC memory for Btrfs WORM storage but lacks an integrated GPU and ships with 1GbE ports unless upgraded). DishyTech’s DC watt-meter tests also show that while Yaosheng DC PoE cuts Starlink idle draw to ~42–55W, enabling snow-melt heating spikes draw to 110W–150W.
UK Statutory & Regulatory Alignment: Ensure OPNsense or RutOS ping watchdogs monitor external DNS IPs (e.g. 1.1.1.1 / 9.9.9.9) rather than the local ISP gateway hop.
