Per-sector capacity is engineering ESTIMATE — ops-grade per-sector data not yet available; build-out pending BEAD award.
Per-sector azimuth, frequency band, and aggregate downlink capacity estimate. Capacity figures are engineering estimates based on equipment and operational parameters; per-sector ops-grade telemetry not yet published.
Open capacity is computed from per-sector engineering capacity estimates and a planning baseline profile (subscribersActive placeholder values — to be replaced by db/towers.js live counts). Reviewers should treat as engineering estimate; methodology swap-ready.
