Carriers tell the FCC these schools have 4G, but in twelve months not one Ookla speed test was recorded within 2 km. Nothing in public crowdsourced data can confirm or contradict the claim.
FCC Broadband Data Collection, 4G LTE, all carriers, map of Dec 31 2025 (released Sept 2026). A school counts as claimed if its H3 hexagon (about 0.1 km²) is claimed at the 5/1 Mbps standard.
Ookla open speed tests from Jul 2025 to Jun 2026, pooled across four quarters, within 2 km of the school. "Checked" means 10 or more tests. "Thin" means 1 to 9. "No one checked" means zero. Where 10 or more tests exist, every school averages above 5 Mbps download.
Around Black Mesa and Whiteriver, each carrier's weak-signal claims were tested against 30 m terrain with an ITU-R P.526 diffraction model, cross-checked with NVIDIA Sionna RT. Towers are either FCC-registered or located from the carriers' own strongest claims. Other areas are not yet modelled.
Speed tests are opt-in and cluster along roads, so a lack of tests is a verification gap, not proof of no service. Physics flags are predictions to check in the field, not findings of misconduct.
